I am wondering if anyone has done some testing on the GG&G Accucam QD mounts to see how repeatable the Zero is after mounting and remounting????

It appears to be the only manufacturer that has a low (1.07")height mount which I am in search of>

Any GG&G users out there??
 
Re: GG&G Accucam QD scope mount repeatability tests

I'm running 2 GG&G Accucam FLT mounts on my AR and AR-22. Both seem to live up to the claims of the manufacturer of returning to within 1/2 MOA upon remounting.

Another benifit is that they do not mar up my rails at all, like other brands can.

I would certainly buy another if I needed one or look at the Aadmount with the 20 moa built in if I needed the range.

GG&G is good to go in my book.

Re: GG&G Accucam QD scope mount repeatability tests

I got one on the .308 mounted w/ NF
I have swapped it out a few times with my NV Scope and it has always returned to damn near perfect , it may not be gnats ass .....but acceptable
+1 on the not marring the gun finish also

GG&G also has excellent customer service , I dropped my .50cal and it broke the mounting cam crossbolt , I sent it in and they sent me a NEWER Updated mount ( they had made some revisions to the older style model that I had ) at no cost

Thanks for the feedback and link for the reduced pricing. I am thinking of the bolt gun model that is only 1.06" high to put on my high receiver DPMS and my Savage bolt gun. Both in 308
 
Re: GG&G Accucam QD scope mount repeatability tests

Another happy user of the Accucam on an LR308. I had a 1" LaRue previously and both the LaRue and the Accucam produced the same results on the rifle. I was using the same ammo for both (current GG&G is holding 30mm Horus 4-16x FFP). I could move the mount back and forth by 1 rail segment and get no POI change.

GG&G mounts are around $75 less than the LaRue...

Re: GG&G Accucam QD scope mount repeatability tests

my GG&G AGOG mount does a good job of returning to zero. I recently picked up a FLT accucam. It seems really solid but I haven't had a chance to test it yet.

So you are happy with the 1" GG&G mount on your high rise DPMS LR 308 receiver and its perform,ance.... got a picture to share??
 
Re: GG&G Accucam QD scope mount repeatability tests

I also used a GG&G accucam for a reflex II a few years back and one for an acog on an m4 for a year in iraq. rock solid mounts... never had a problem with them. Im a big supporter of their mounts. Never tried anything for regular tube scopes with them though as I have a few Larue SPR mounts.
 
Re: GG&G Accucam QD scope mount repeatability tests

I have the GG&G eotech mount on my Eotech 552 and it works great, no problems
 
Re: GG&G Accucam QD scope mount repeatability tests

i run a GG&G accucam on my eotech 512 and i have removed it numerous times and still get great groups at the same zero

i would trust it
 
Re: GG&G Accucam QD scope mount repeatability tests

Sounds like most people use the GG&G mounts for non-scope optics....not that many response regarding use of their mounts with precision scopes..
 
Re: GG&G Accucam QD scope mount repeatability tests

That's a good looking mount, I'm gonna run one of these when I get my Nightforce back. My old Arms #22's (10 + yrs.) don't lock down as snug as they used to. They worked really well for me but I like this GG&G unit. I also would like to hear from other who have used this mount.

I have that one except it is the taller version. I compared it to all the others and for the price it's a very nicely made piece of equipment. I really don't understand buying one for $350-$400. If there is actual proof that a $350+ mount compared to this gives drastically better results then so be it and I will openly apologize but until then those companies are greedy in my opinion. Theres also a bit of disagreement by some that having 2 or 3 locking levers is better than 1 but looking at how this thing is made the point of contact isn't just where the lever is but it runs along the entire thing. It has 3 separate tension areas that you can adjust as well with allen keys. Theres also no need to lap the ring area because it appears to be formed out of a solid piece of metal so the probability of rings being out of alignment are slim to none. I have a LaRue 5/8 riser on my AR and the locking mechanisms have gouged a little valley into my AR upper picatinny rail. For $125 LaRue can eat a dick.
 
Re: GG&G Accucam QD scope mount repeatability tests

I had the Accucam standard base with Burris rings holding a Bushnell 4-12 on my AR15, took it on and off several times, zero was generally within 1/2MOA as advertised. I say generally because it is reliant on you doing your part to make sure it is postioned in the same spot with roughly the same amount of pressure against the lug when latching it down. I like this product and the other GG&G products I have and will likely get a FLT in the near future, it has never loosened, never unintentionally released, is easy to operate and doesn't mar. One thing to watch, haven't paid attention to how their mounts compare and it may not matter, their stuff is stout, but it can also be a bit on the heavy side.
 
Re: GG&G Accucam QD scope mount repeatability tests

Well I have a Accucam QD for bolt gun inbound in a couple days. Will test it's repeatability and report back for whoever's interested. I think it's gonna work just fine.

Looking forward to your review, as I've also been searching for a low QD mount and the GG&G seems to fit the bill.

Re: GG&G Accucam QD scope mount repeatability tests

As the OP, I did make the leap and ordered the mount as well, however, I am a noob, so my tests will not be as valid as a more experienced shooter right now.
However I will post my general impressions asap.
 
Re: GG&G Accucam QD scope mount repeatability tests

Thanks Toshu. Just generally, I'm interested in, if you have the rifle zeroed and you remove the scope, is point of impact changed when you put it back on? Over multiple removals and reinstallations has it shifted? If switching rifles if you have a known difference in zero between Rifle A and Rifle B (say it's only 3 MOA in elevation) when you switch can you just dial in the 3 MOA and be getting hits that are on? Or does the rifle to rifle shift change with switching?

Also curious if you store the rifle with the optic removed. If yes, any problems when you're mounting it back up?

FWIW, I have a Bobro on my AR15 and I store with it removed, and no problems putting it on when I get to the range and being able to be dead on. Only problem is I'd like something a little lower for my bolt gun.

Thanks!
Mitch
 
Re: GG&G Accucam QD scope mount repeatability tests

Mitch,

I looked at the Bobro, which has been well reviewed and tested well by LoneWolfUSMC here on SH, but it was too high since my AR 10 has a high rise upper already on it.

will keep you posted as I get it, and play with it. Hopefully others will chime in as well with their experiences and testing.
 
Re: GG&G Accucam QD scope mount repeatability tests

"Not be as valid", relax. Fire a 10 shot group at 100 yds to establish a standard. Then fire another 10 shot group next to the first removing the scope/mount after each shot. Take your time and squeeze off some good rounds. That'll show how well it will hold zero.
 
Re: GG&G Accucam QD scope mount repeatability tests

Like I said before, good looking unit. Clamped on to that Badger base solid. My rifle was shooting extremely well with the worn Arms #22's I had on there before, it'll be good everything's on there tight again. Looking forward to testing it's repeatability. Forgot to mention, the ring height on this mount is medium not low. I clamped a medium #22 ring in front and the GG&G sits just a hair lower. I'm used to low rings but this will do considering the height of most other mounts of this type available.

Re: GG&G Accucam QD scope mount repeatability tests

Flyfishguide - thanks for those photos and initial thoughts on it. I'm looking forward to both your and Toshu's field testing.

Re: GG&G Accucam QD scope mount repeatability tests

Just keeping Toshu's thread current. Received my 5.5-22X back from Nightforce yesterday. Had it converted to .1 mil, HS, ZS. Gonna head out in a bit to track the scope and test the mount's return to zero, will post results later today.

Re: GG&G Accucam QD scope mount repeatability tests

Flyfishguide,

nice set up.
I got my mount today and will try and take some pics of the mounting mechanism since that was of interest to me and I am sure it will be to others.

Unfortunately I will not be able to mount and shoot mine for a few weeks, but will post info here as well.
 
Re: GG&G Accucam QD scope mount repeatability tests

Toshu, gents. OK, here are my results. Short and simple, no B.S. I decided to use this calendar as my target at 100 yds. The red aiming points are 1/4" diameter. After getting her on paper, I walked her up to zero on the 4th. Then fired a 10 shot group on the 6th. Then another 10 shot group on the 8th, completely removing the mount after every shot. First round was on but the other nine shifted .8 mil (2 7/8")high. You can see group above the 1st. I said WTF. So I rezeroed on the 25th then fired 1 shot each on the 26th thru the 30th. Again removing mount after every round. .8 mil high again. So make your own conclusions. It's consistently repeatable, except not to my zero.

Re: GG&G Accucam QD scope mount repeatability tests

Great shooting on your part, but strange results.....????
Are you giving the mount forward pressure each time??

need to think about this....

Here are pics I just took of the mount underside

Re: GG&G Accucam QD scope mount repeatability tests

I torqued everything down prior to going out and was consistent in pushing mount forward. I was expecting minimal shift around my zero. Heck of a 9 shot group, I thought, considering removal and mounting after each shot yet not one returned to zero.
 
Re: GG&G Accucam QD scope mount repeatability tests

How are you checking the torque pressure when you engage the lever?

</div></div>

But the odd part (which is positive) is that the 9 shot group was almost as tight as your original 10 shot group. ...that suggests something odd is going on here that we are missing.

Might be worth contacting GG&G

I spoke to Brant Sabau who is their Sales Director a few weeks ago to learn more about the product at 520-571-6018. I am sure he would be able and willing to help figure this situation out with us.
 
Re: GG&G Accucam QD scope mount repeatability tests

Regarding torque, I meant base, ring, and action screws assuring those were'nt factors.
 
Re: GG&G Accucam QD scope mount repeatability tests

I've never seen any scope taken off of a rifle and put back on and seen perfect return to zero time after time, always a click or two off. The one time i saw the perfect return to zero it wasn't repeatable the next go around
 
Re: GG&G Accucam QD scope mount repeatability tests

Still scratching my head, but not worried about it. First 10 shot group clearly shows it will hold zero as long as I let it be. I'm gonna give her a good run out to 1,000 yds on Sunday. As long as I get good hits, I'll run it. It be good to hear from others running this mount. We can't be the only ones.
 
Re: GG&G Accucam QD scope mount repeatability tests

OK gents, for me this mount is good to go. I am not concerned so much that it does not return to zero when removed. I took my rifle out Sunday morning, checked it's zero, then fired at 817, 488, 980 and back to 523 yards and all were on the money.
 
Re: GG&G Accucam QD scope mount repeatability tests

I have been really happy with the quality and the return to 0 of the GG&G items. They are not as solid as a GDI mount but they are nice.

Mike,
do you have any data to share WRT POI shift from remounting ???

Good to hear that the mount stayed on zero for your tests this weekend!!
Perhaps the results of the test were a fluke, or a result of not quite seating it all the way forward due to its design??

Over the weekend I thought about the initial results, and what might be happening is that each time you disconnect and reconnect the mount, perhaps there is a POI shift due to the mount not being seated...then if you fired 2-4 more rounds, would they come back to the original zero after the mount settled in????

Remember the 1 of the 10 that apparently was your first shot, and it was on zero....perhaps in that particular cycle, the mount was fully seated???
