I heard this event - both sides, were being set up on behalf of Karmelo Anthony to try to demonstrate "social/racial unrest" in Frisco to get the trial moved out of Collin county, which could have a huge impact on the outcome. I'm glad no one showed up.

Busy work season so I have only been gleaning snippets of this and that here and there, but word right now is that this is not going well for that hoodrat Karmelo Anthony. Karmelo has been accused of previous incidences where he also threatened and assaulted others with a knife. His mother has been revealed to be a habitual liar, and the dude they hired to be his attorney is a violent felon with over 15 previous convictions in a variety of assault, sexual, and property crimes...

I Spy New Baby Razor G3 4-24

Electronic ones. I already have that in the Element HYPR-7. Eventually, that (or similar) technology will propagate through the scope world.

With conventional glass etched reticles, there will never be a high quality riflescope that offers a user swappable reticle.

@koshkin How do you like that HYPR-7? I've been looking at them.

DNT The One vs Athlon etr 4.5-29

Maggot
I have both in mils and did a brief comparison the other morning, but it was cold as ....so I want to do more in depth. my initial impression is that the Cronus 4.5x29 G2 os optically superior to the DNT 7x35.....but not by much. Cronus seemed to have a bit better definition and texture to the image where as comparatively the DNT seemed slightly flat. Very close on light transmission. That showed up more at higher mag. Ill look again tomorrow and add some more.

SR 25 Scope Recommendations

91Eunozs
It’s not an SR25, but have a NF NX8 2.5-20 on my 16” AR10 chambered in .308; it’s perfect for this rifle.

For an SR25I’d step up to an ATACR 4-16 though. The ATACR 4-20 is a bit too long IMHO; harder to use a clip on.

Alternatively, the S&B 5-20 ultrashort would be a great choice. I have an older version of that one on another rifle and love it despite the weight. Great scope.

"Over Gassed" AR's Fact or Fiction? Other Perspectives

T
Flexible Tangerine Sprite said:
I see a lot of postings suggesting AR failure to feed malfunctions may be because their rifle is "Over Gassed" and I really have to question this. For backdrop, I have built up and test fired in excess of 500 AR-15's, many of them with custom or wildcat cartridges, and with a myriad of barrel lengths, gas system lengths, etc., where there was no recognized or normally accepted port sizing (had to figure it out).

One of the main arguments of the failure to feed malfunction as relates to "Over Gassing" is that the bolt carrier and bolt speed is too fast.

I have yet to see "Over Gassing" as a source of a failure to feed malfunction to be a real issue for a few reasons:

1. The speed of the carrier and bolt coming forward to feed a round is almost 100% governed by the stiffness of the buffer spring and the weight of the buffer.
2. If a rifle is "Over Gassed", that may speed up the retreat of the carrier and the unlocking of the bolt out of battery, but it does not per se speed up the carrier and bolt coming forward (i.e. the buffer typically hits the back of the buffer tube and the dead plastic end of the buffer softens that strike so it's not metal to metal, but it's not a trampoline effect, nor was an AR buffer system designed to do that).
3. An AR gas system is set up to bleed off all gas immediately after the bolt opens out of battery (i.e. it blows out the vent holes in the side of the carrier) so it's not like the system holds onto excess pressure to somehow convert that into carrier or bolt speed coming forward.

I am also not a big fan of adjustable gas blocks and I have seen plenty of issues with them (taken a bunch of them off customer guns a returned them because they were a source of a problem that did no exist). First off, an adjustable gas block is of no value at all unless the rifle is over ported. All an adjustable gas block can do is cut back the amount of gas being delivered into the gas system from the port, it can never add more than can come through the port. It may have some value for someone that wants to run something like a 300 BO where they want to shoot subsonic "heavies" with a real fast powder through a can to run very quiet (ergo they have a very large port to do that), but then wants to shoot supersonic and push bullets to the max where chamber pressures are running double what they are with a subsonic loading. Even then, what I typically see is an AR cycling back hard and ejecting aggressively but that's about it.

I have probably "opened a can of worms" here with this discussion but there are other perspectives on the issue involved.

I don't know that I've had the occasion to assemble or diagnose that many ARs in my lifetime, but I don't think I agree.

Energy is equal to mass x velocity. Every action produces a reaction. The faster the bolt carrier is moving when it hits the bottom of the buffer tube, the faster it will be moving on the return stroke. If you drop a baseball from waist high onto concrete, it might bounce 4". Drop that baseball from 20 feet high and it will bounce higher. That's because when dropped from 20 feet, it will have attained more velocity by the time it hits the ground and, therefore, will have more energy. Same principal with the bolt carrier group. It isn't just about the spring and weight of the buffer.

In extreme cases, I have seen too much bolt velocity cause an AR to malfunction. You can mitigate this with a heavier spring to bleed off some of the energy of the BCG, but that won't fix the problem of insufficient closed bolt lock time, but that's a whole different discussion.

Precision Rifle Gear Bipods?

Fig
I disagree. Much faster to grab a leg and pull rather than finding a button (especially when cold and gloves or low light).

Accu-Tac is not a best all-around bipod, They're made for shooting .22s or free (modified free) recoil where you do not load the bipod. The guy who owns Accu-Tac comes from air guns, which is why they're so tight with no play. For heavy recoiling rifles I prefer Atlas or EI though.

Unless I'm shooting up and need elevation (or transitioning up and down), I almost never shoot prone with the legs straight out. I almost always put it on the spigot mount (as far forward as possible), put the legs forward at a 45 to get the rifle as close to the ground as possible, and use a small squeeze bag as rear support rather than a game changer or other big bag. I see lots of guys extending legs and getting the rifle high with a big bag, but I wasn't taught that way, and it seems less stable to me. If I need the gun high (like to see over grass coyote hunting) I go to a tripod rather than a long leg bipod,

Accu-Tac kind of sucks on a heavy recoil gun, because they're hard to load, don't stay put, and will jump on a hard surface even if you are perfectly positioned and do everything right. On low/no recoil rifles though they're damn near perfect IMO.
