For those that have tried Staball match with 6gt, how has that worked for you? A friend of mine has been getting single digit SD and sub 25 fps ES dropping powder on a progressive press. Is he a lucky guy, or is this pretty common? I have seen others reporting just ok results with it in 223 but cannot find much info on staball match with other cartridges that like the varget burn rate powders. Thanks.

I have 2 500ct boxes 105 hybrids same lot number and sealed $450 shipped for the pair.

Just to keep people in the loop
Emailed Pat at PMA Tool this past week and they are doing a heavy run on a lot of their bore guide models this week.

What are the options available today for a pair of laser rangefinder binoculars with a MIL reticle? Ballistic software not needed for my application. Is there an option in the $1000 - $1500 range? I did a quick search of the major players and couldn't find anything.

Edit: is this still a gap in the market in 2025?

The German Army has chosen the CZ P10F O.R. to replace their old HK P8/USP pistols. The CZ was chosen over the Glock 17 and the Arex Delta 2.

Apparently no HK, Walther, or Sig pistols, were down selected in testing by the German Army.

Contract is for a minimum of 62,000 pistols, and could go as high as 186,000 pistols.

Good for CZ- the P10 is a great pistol!

So I've been stacking manners certs all summer, ordered my stock this spring went to pay for it and saw the fine print on the gift cards. "one per stock" well crap.

I have 2 that are $250 each I'll sell for $100 each. Exp dates are 1 month apart on these but first buyer gets choice. You just have to have your stock on order by mid 2026 *one sold to Chgunz* ***both sold***

I have one that is a $500 that I may keep or trade for another cert. What I don't know. Maybe a foundation or? I have vortex and leofoto certs already. Or if someone really wants it $400

PayPal F&f or venmo, I'll send a photo of the back of the gift card after payment.

Optics Tested:

• EOTech EXPS3 holographic weapon sight
• Trijicon Patrol MRO reflex red dot weapon sight
• Holosun 530-RD reflex red dot weapon sight

Summary of Measurement Results for Parallax Induced Point of Aim (POA) Error:

• Contrary to widely held belief, the EOTech EXPS3 holographic sight has about the same parallax induced POA error as compared to reflex red dots Trijicon Patrol MRO and Holosun 530-RD, which was surprising to learn.
• The parallax induced POA error is between 3 MOA to 5 MOA for the EOTech and the two reflex red dots tested.
• To see the measurement results and learn how the measurements were made, read on.

I hope some Hide members will find this useful. Please don’t shoot the messenger, the EOTech sights are awesome and many shooters love them including some of the most demanding expert military and LE operators. I did my level best to design and execute a basic scientific test for comparing red dot parallax error between different red dot models. It’s also pretty easy for others to repeat the test to see if others get similar results.

Introduction:

I recently purchased an EOTech EXPS3 with a flip-down magnifier because I thought it would have much less parallax induced POA error than my red dot sights. Two other motivations for trying the EXPS3 are that with holographic sights the center dot diameter does not increase in MOA size with magnification and the window size and FOV is larger as compared to most reflex red dot sights.

Parallax error in a CQC weapon is important in my view because shots are often taken under time pressure from highly improvised positions with a non-standard cheek weld or no cheek weld at all. The more forgiving the sight is with respect to where the dot is located in the window, the better. Holographic sights, including EOTech sights, are widely reported to have far less parallax error as compared to reflex red dot sights. Some of online and print sources even claim the EXPS3 sight is "parallax free".

This is the only reference I was able to find that has measured red dot sight parallax error results, and the results say that EOTech holographic sights are not parallax free but have significantly lower parallax error than most reflex red dots:

Parallax Induced POA Error Measurement Procedure:

The first thing I did when the EOTech arrived was to unbox and place the sight on a stable aiming platform with approximately 9.5" eye relief for an apples to apples comparison with (1) a Trijicon Patrol MRO (MRO-C-2200018) and (2) a Holosun 530-RD (HE530G-RD). The test procedure for each sight was to center the dot in the middle of the window while aiming it at a grid target with close grid spacing, then move my eye side to side by the same distance for each sight (+/- 0.5”) and up and down by the same distance for each sight (+/- 0.35”) and then record the dot movement in inches on the grid. The target was set up at 7 yards which was far enough away to get enough dot movement for a reasonably accurate estimation of POA shift on the grid, but not so far away so that the grid lines were hard to discern at 1x. The smaller vertical eye movement as compared to the horizontal eye movement was to account for the smaller vertical window dimension of the EOTech as compared to the horizontal window dimension. Although the Trijicon and Holosun are round which would allow the same vertical and horizontal eye movement, the vertical eye movement was limited for all three sights in order to maintain a consistent comparison. This test procedure is not very rigorous, but the results allow for a reasonable relative “ballpark comparison” of the three sights. The results are definitely “good enough” to determine whether the EOTech parallax error is clearly superior or about the same as the reflex sights.

The bottom line - The EOTech has pretty much the same parallax error as compared to the reflex red dots, which was somewhat surprising to learn.

Another interesting finding was that the Trijicon has the smallest horizontal POA error when the eye is moved in the horizontal direction, and the smallest vertical POA error when the eye is moved in the vertical direction, but there is a translation of horizontal eye movement to vertical POA error and a similar translation of vertical eye movement to horizontal POA error. I have noticed this in the field when using the MRO but this is the first time I measured it and it was surprising to find that the horizontal to vertical and vertical to horizontal translation errors were larger than the vertical to vertical and horizontal to horizontal errors.

Measured results in inches of error for parallax induced POA error at 7 yards distance from the front of the sight to the target:

• Approximate EOTech EXPS3 POA error induced by +/- 0.5” horizontal eye movement: +/- 0.35” horizontal POA error, negligible if any vertical error.
• Approximate EOTech EXPS3 POA error induced by +/- 0.35” vertical eye movement: +/- 0.2” vertical POA error, negligible if any horizontal POA error.

• Approximate Holosun 530-RD POA error induced by +/- 0.5” horizontal eye movement: +/- 0.35” horizontal POA error, negligible if any vertical POA error
• Approximate Holosun 530-RD POA error induced by +/- 0.35” vertical eye movement: +/- 0.25” vertical POA error, negligible if any horizontal POA error

• Approximate Trijicon Patrol MRO POA error induced by +/- 0.5” horizontal eye movement: +/- 0.15” horizontal POA error, +/- 0.2” vertical POA error
• Approximate Trijicon Patrol MRO POA error induced by +/- 0.35” vertical eye movement: +/- 0.1” vertical POA error, 0.2” horizontal POA error

While the above error measured in inches are small for a CQC engagement at 7 yards, when the errors are converted to MOA they are substantial for 100 to 300 yard engagement distances.

Measurement results in MOA for parallax induced POA error:

• Approximate EOTech EXPS3 MOA error induced by +/- 0.5” horizontal eye movement: +/- 5.0 MOA horizontal POA error, negligible if any vertical POA error
• Approximate EOTech EXPS3 MOA error induced by +/- 0.35” vertical eye movement: +/- 2.9 MOA vertical POA error, negligible if any horizontal POA error

• Approximate Holosun 530-RD MOA error induced by +/- 0.5” horizontal eye movement: +/- 5.0 MOA horizontal POA error, negligible if any vertical POA error
• Approximate Holosun 530-RD MOA error induced by +/- 0.35” vertical eye movement: +/- 3.6 MOA vertical POA error, negligible if any horizontal POA error

• Approximate Trijicon Patrol MRO MOA error induced by +/- 0.5” horizontal eye movement: +/- 2.1 MOA horizontal POA error, +/- 2.9 MOA vertical POA error
• Approximate Trijicon Patrol MRO MOA error induced by +/- 0.35” vertical eye movement: +/- 1.4 MOA vertical POA error, +/- 2.9 MOA horizontal POA error

Another interesting finding was that although the Trijicon sight exhibited horizontal/vertical translation errors in POA, the total POA error for a given amount of eye movement seemed to be a little less than the total error for the same amount of eye movement for the EOTech and Holosun sights. This makes me wonder if the Trijicon engineers designed a reflective surface shape to minimize total error at the expense of some translation error, or if this just happens to be how the design of the Trijicon reflective surface shape works. It is an individual shooter decision as to whether the translation in POA error from horizontal to vertical and vice versa is acceptable in exchange for a slightly smaller total POA error.

Take aways:

• Based on these test findings, the reported EOTech EXPS3 improvement in parallax induced POA error as compared to some of the best red dots is not accurate. The EOTech parallax induced POA error is about the same as a good reflex red dot sight. I suspect, but do not know, that the same may be true for some of the other EOTech sights because this is one of EOTech’s most recently released models so it would be surprising if the parallax induced POA error is worse than the earlier models.
• It is important to state the obvious. The bottom line for practical use of all red dots is that centering the dot in the sight window during both zeroing and shooting longer distances is very important for accuracy.
• When using a flip-down magnifier with either a holographic sight or a reflex red dot sight the window sight picture and FOV is greatly reduced, which naturally forces the shooter to keep the aiming dot more toward the center of the sight window, but it is still important to center the dot. It is also good practice to zero with the magnifier because any POA MOA shift due to the magnifier being on and off will produce a larger error measured in inches or cm at distance under magnification if the sight is zeroed without magnification as compared to the error in inches or cm at close range under 1X power if the sight is zeroed with magnification.
• Even though the parallax errors are about the same, the EOTech EXPS3 and other EOTech models have the other advantages over reflex red dots. These advantages include a large FOV window and the same size aiming dot under magnification. While some red dots have similar FOV window sizes as compared to the large window EOTech models, the reflex sight aiming dots expand under magnification. Therefore, if the shooter is careful to keep the aiming dot in the center of the window the EOTech models can still be more accurate than a reflex red dot at long range under magnification due to the higher resolution of the aiming dot.
• For me though, the main attraction was better parallax error and I'm not willing to trade the extra weight, size, cost and much lower battery life as compared to the excellent large window reflex red dots that are available for what amounts to a smaller, more precise aiming dot when using a flip-down magnifier. The EXPS3 I bought is going back to the seller.

Notes:
I have been using the Trijicon Patrol MRO for about 10 years and although the same model number is still a popular option that is readily available, optic manufacturers sometimes update designs without advertising the fact so newer Patrol MROs might have internal design updates that could change the parallax error performance, I don’t know about this. The EOTech EXPS3 is brand new and I picked up the Holosun 530-RD about 6 months ago, so these should be the latest designs.

Looking for some insight……

Working on an AR 450 bushmaster. 16 inch generic barrel with carbine gas system. Standard gas block and buffer / buffer spring. Nothing fancy and not my build. Just trying to tune this dag blame thing for a friend!

When it cycles it throws the brass to about the 2:30 position indicating it is over gassed but it is only spitting the brass out about 18 inches from the receiver which makes it look like it’s under gassed. Rare occasion it will cycle correctly and load another. Most of the time the bolt catches the brass (not the case head) about middle of the case. Then it jams. I’m leaning towards undergassed but the 2:30 ejection has me baffled.

Sorry for throwing gas on the dumpster fire, I looked and couldn’t find any threads dealing with this. Has anyone ran into this sorta thing before?

Does anyone recognise this 34mm diving board ring?

It fits on an AI scope mount, but I've never seen it before. I know that AI RIS rings aren't made by AI and this also doesn't seem to be made by AI.

Just wanted to introduce myself. Recently retired and finally have some time to get back into hunting, shooting and golf. I'm new to wearing glasses. My whole life I've had 20/12.5 vision. With glasses though, I find it takes more time to find the sweet spot through the scope. Would contacts be better for shooting? I don't know, have never worn contacts and do not know the ends and outs.

Anyway, thanks for having me as a new member, and Semper Fi to all of you Marines.

Looking to replace the handguard in the image and not sure what I need. Will a new handguard come with everything I need to install/mount? Pretty sure I have all the tools needed I just don't understand how the handguard mounts to the upper based on what is in the image. I'm also having trouble removing the gas block., I've loosened the allen screws on the bottom but it only slides about a 1/4". Is there a specific handguard where the Pic rail on the upper mates with the pic rail on the handguard?

Now if I can just get my work schedule to cooperate with the NRL Hunter schedule:

Gently Used Nordic Components AR Ruger 10/22 Chassis. Also included Hogue Grip and No-Name 15" M-Lock style rail. All for $SOLD shipped CONUS.

My set-up shown for illustration purposes only. Kids had a blast.

Along with the mounts from ICE.....

Here is another option for everyone. The first batch will be ready in 2 weeks.

I showed the mount to Marty at Badger and to George at GA Precision as well. They both liked it and said it looked great. George put a order in for 25pcs direct to the maker this week.

From the two I looked at... I'll say ring gap is .015". I grabbed a older 1" scope I have laying around and thru it in the rings and tightened the rings down to measure the ring gap. When I took the scope out of the rings nothing got crushed and only faint ring marks but no gouges etc... The only other scope I have that's a 1" anymore for the tube diameter is my Unertl and for me shooting my M40A1 I need the eye relief that the Badger scope base gives me and I'm using the M40A3 rings on it.

I took one of the mounts and test fit it to two receivers. I needed to take about .003" off each side of the rear lug and .030" off the backside of the rear lug. After doing it that it dropped on to a factory clip slotted 40x receiver. I needed to take a file and bevel the back corners of the rear lug to get it to go onto my GAP built M40A1 rifle and it fit pretty snug. A little snugger than the 40x.

Price on these will be $540 plus $11 shipping to the lower 48 states.

After this initial offering I will turn it all over to the manufacturer. Retail right now it's at $600.

No drop in mounts are available on these ones. No left handed mounts are available either from this maker.

Here are some pic's.

Later, Frank

Went shooting earlier today and took my R700 223 Wylde with a 28" Bartlein 8 twist shooting 75g ELDMs at 3000fps with 24.7gn N540 in Lapua brass and Rem 7.5 primers at .025" off. I wanted to see what a 10 shot group off the bench would look like. About 70 degrees, 1-2 mph winds, little bit of mirage, but not bad. The result was approximately a 2.5" group. Now if I was to cherry pick, I'd say the 5 shot cluster was from 1 group, and the other 5 were from another, but that's not how it went haha. With that said, how happy would you be if this was your rifle? Would you try to further improve on this, or just load them all up and just shoot? I definitely feel the rifle is capable of more, whether it be a different bullet or powder, maybe tune the current load as the numbers on the Garmin aren't to promising with the ES/SD. I also put the last 5 rounds on a 2/3 ISPC target into approx 3" at 500 yards to end the day.
