2021年11月24日 · I have a WOA SPR contour barrel on my Mk12 Mod 0 and a Bartlein SPR on my Knights SR 15. Both shoot sub MOA groups, with each giving me a few 1 hole groups over the years with my handloads. My 12th model fit better on the WOA without needing any additional machine work to get the proper thread engagement on the suppressor.

2020年2月26日 · Noveske’s 18” SPR barrel is a stainless-steel barrel that has a medium contour and a 0.750” diameter gas block journal. The gas block journal for this barrel is designed for Noveske’s low profile gas block and the journal is only one inch in length; standard length gas blocks will not work with this barrel.

2018年1月3日 · Then they sent me the above SPR barrel as a substitute for the QPQ barrels as I was done with QPQ. I have since polished the chamber and fixed the brass problem. Then I bought a BA 7.5” QPQ pistol barrel and that one keyholed with Rem UMC 55gr ammo. It does shoot other ammo just fine, so I’ll blame this issue on the ammo/barrel combo.

2021年5月19日 · About to install it after I pull my 18” BA SPR barrel off when I get time. Like I said, I sent it in fall of last year bc I knew I was going to install it sometime soon and that’s when she told me they were going to change their spec. I’d call and ask. My 16” WOA SPR I ordered on Black Friday last year is the correct 2.4”.

2016年6月30日 · For me it would come down to what optic I was going to be using with the barrel. I'd run a red dot or a 1-6x on a A2 or lighter profile barrel, but would opt for more magnification on the heavier SPR profile. Going to be putting a 2.5-10 on a Larue Stealth barrel soon.....btw the Larue barrels are on sale till the 4th...

2017年4月19日 · I have an 18" PSA 'SPR/DMR-ish' rifle that I am looking to rebarrel with an upgrade barrel. I would love to drop the coin for a White Oak or similar barrel but, simply, family and other obligations have to come first. So, I could use some recommendations for a "Best Bang For The Buck" replacement barrel.

2017年3月20日 · Kreiger Mk12 SPR barrel. 17.9" 1:7 twist. $470 Right now the Criterion is the leading candidate and the Centurion is second. The Criterion is leading because of the price and I've heard good things about the cuts at Compass Lake. I know the Centurion Arms is the real deal barrel and the same as the military Mk12 barrel.

2021年1月13日 · Hello everyone, I have been tasked by my brother in law, no kids and high paying job, to help him build an SPR. I'm relatively new to the AR platform myself, just built mine last year. He has basically given me a budget of around 5K for an upper. The goal of this upper will be just target...
