Hi, this is a new built 308, with Criterion 20” bbl chrome line, only shot 20 rounds just to make sure rifle is working, so far its 100%. But notice some marks on the neck, could be a rough feed ramp?, pics below

Thanks, really a big help, so i can go 1.40-1.43” mount, always prefer 1.5-1.6” on my AR-15

Hi
I am in the building of a 308 AR using Stag 10 receivers which a high tang DPMS . Already have the parts except the scope ( Vortex Razor 2 E 1-6) already placed an order , thinking of getting the Geissele Mount )( 1.50”), centerline height , should I get the sopmod or just the regular extended mount?, second concern is about the term high tang, will the top of the Picatinny rail higher vs the stock drop compared to a AR 15 223?, found a Warne mount , big price difference than Geissele, but its on the low side 1.43” centerline which i find a little bit low especially with my fatty check, that is on the AR15. Your opinion is needed here. Thanks

School me on the 2 reticles( vmr and JM) they look the same , any difference between the 2. Will replace the Swarvo Z8 1-8 that’s on my 3gun With the Razor, the Swarvo will go to my Stag 10, will be for plinking and range use .. unfortunately can’t afford a another Swarvo or Khales for my 3gun rifle, what do you think should the PST2 1-6 for 3 gun, quality wise, your opinions are welcome. Thanks
btw can you recommend a good dealer price price for the Razor

Shooters Connection doesn’t ship international for gun parts either, but thanks for the link

Hi
am I correct to say that the GMR15 extractor is the same as 1911?, since we don’t have a JP dealer here up North and JP doesn’t ship, I’m desperate to have a back up, same with the firing pin/spring too, although Brownells ships international , BROWNELS don’t sell these parts even with my product request to them, but saw a Wilson AR9 firing pin on their website , not sure if its JP bolt compatible. Thanks

Update, Hornady Tactical Defense BS 8 pellets using IC produced the best pattern, but was not able to compare with/ without the brakes, maybe next week
-
thanks for your feedbacks, will try it on the rsnge Monday without the brake snd IC choke

Hi, Now shooting open with Typhoon F12 and it comes with after market muzzle brake... my Buckshot seems will not pattern as tight as I want, tried different chokes from LM, Mod and IM ... SB , Remington and Federal ammo were also used.
Does a brake affect how a gun patterns? Will try shooting without the brake and see what happens... any feedback will be appreciated. Thanks
-
Are the firing pin and springs proprietary just for the GMR15?, how about the extractor,
-
The firing pin and the extractor are issue, you can’t simply mail the part up here, will make more research on other companies that are legal to export, emailed Brownells if the start stocking these parts, btw are the firing pin and extractor proprietary, it looks like the extractor is the same as 1911, and the firing pin as standard AR 223, might be wrong though
-
I want to keep in hand some spare parts, ( firing pin,,extractor snd oring) JP doesn’t ship to Canada, although Brownells carry JP parts snd ship, but they don’t have the parts mentioned above, any recommendation of other source, thanks
-
lots of 10 rounders here, but remembered JP recommends the standard 17 rounds for reliability, more something like the different follower design of the 10 rounds. although the 17 rounds are prohibited here unless pinned to 10 which is legal. and find the 10 rounders is a pain to load on close bolt.

i have a couple of glock mags, but they seems always out of stock here up north
-
any feedback and experience with the Amend2 for use with GMR15. any reliability issues? thanks
-
Thanks,
-

Looking to put the 510C on a JP GMR 15 - trying to determine if I automatically need a riser or shoot it first to see. I’ve only shot a friends MPX and he had a large riser under the Romeo 5S. If I need a riser who is recommended (FDE)? Thanks for any insight.
Also shooting GMR15 with 510C, i find the factory height a little low , Was able to get a spacer (.200) to raise the 510C to 1.61”, which is an improvement . Always shoot with my Red Dot to 1.70”. . Holosun sells the spacer. But have to source mine here locally since Holosun doesnt ship up North.

Correction. I cleaned and checked my 1050; reconfigured my loading data and then rechecked my N320 loading. I am switching back to N320 because now my drops and loads are dead on. My deviation is +/- .1 on the drops. So now my current PCC load is 4.2gr N320 @ 1.130; this gives me about 135-140 PF in my GMR-15.
BiggMike
do you mind sharing your N320 load for your GMR15, I did try 3.8 and it was a soft shooting load but the accuracy was not satisfactory, then bump my load to 4.1 gr and accuracy is now great. btw I'm using Frontier Match 124 gr. 1.125" OAL, thanks

So i can use one of the springs thats comes with the (5pak) for my PCC? Say the 100or 95%, thinking of using the 90-85% for the 223, running adjustable GB on my 223.

Thanks, somebody mentioned not on BE that the 9mm use their 308 spring?
