Thought I would put on my "spare" barrels on my AR10s. My AR10 got a Noveske 21", and my other AR10 got a 16" Rainer Arms Schillen Ultra Match

Beautiful Noveske Markings

Noveske Gas Port Hole Slightly smaller than the Armalite SASS port. I think this will be OK as I felt the SASS was slightly overgassed. Also the Noveske barrel is 21", and not 20" so the 1" extra dwell time should increase the gas pressure. Only way to find out is to function test. If it does not cycle then I will modify the gas port hole on the Noveske Barrel.

I am a firm believer in putting Red Loctite on the Barrel Extension

Headspace time. Kickass Bolt tool from Brownells (ejector removal). This tool one tool works for both AR10, AR15, Savage and Remington700.

Noveske Barrel closes on a .308 SAAMI 1.634" "No-Go" Gauge. Not a big deal as Noveske calls this a NATO Barrel and NATO specs allows 1.638" for No-Go. I have many guns that closes on a .308 SAAMI No-Go and rifle functions just fine, and is also fairly accurate. I myself think for Gas Guns you want the tolerances to be looser for reliably cycling, and also a slightly looser headspace allows gun to shoot when dirty better, and gas guns tend to foul up faster than bolt guns. The Rainer's Arms barrel did NOT close on the 1.634" Gauge.

Does not close on a SAAMI 1.638" "Field Gauge", The 1.638" SAAMI Field Gauage is basically a NATO "NO GO" gauge

All ready for function test at the Range!

Found out the Noveske Barrel worked great at the range without any mods to the SASS Gas System! The Rainier Barrel for my 16" AR10 also worked great. Both rifles worked great right right out of the box as both cycled every single round without issues. Here are the pics of both Rifles:

Shot mostly my 147gr Reloads. I did shoot for groups, 4 times (5 shots each) for each rifle with my 175gr SMK recipe for Semi-Auto. With my 21" SASS with Noveske barrel and my 175gr SMK reloads, the worse 5-shot group was just over 1.2" (at 100 yards) and the best group was just over half-MOA. Here is the pic for the best group with the SASS/Noveske. I think with Load Development, I might be able to get more consistent groups and stay within .75 MOA.

My 16" AR10 with Rainier Arms Barrel surprised me. I can never get a good POA with a 3.5x ACOG and the Triangle. I was expecting 3" groups like I get with the Factory lite barrel, to my surprise, worse group was only 1.5" (at 100 yards, and best group was about .85". I think with a nice magnified optics and load development, this thing could be around consistent .5 to .75 MOA.

Nothing wrong with my old barrels, just wanted to see what these barrels can do. I really like the Rainer Match barrel for the price. It is way more accurate than the Factory Chrome Lined Barrel. But also it's heavier and it will not have the longevity of a CL barrel.

Noveske Barrels get a lot pub, but so far it gets about the same size groups that the Armalite SASS barrel that it replaced. My SASS Barrel is still basically new and has only seen 1100 rounds, it is always nice to have spares you know that works.
 
dude, awesome friggen post and killer information.... im impressed. nice work. too bad I don't live closer i'd head out with ya brother... I always like your posts.

Boulder City Range, about 20 miles from Desert Sportsman, and it is a way better range than Desert Sportsman.

NICE shooting
The wife and I are flying out to Vegas next year. I love driving out to Lake Mead, going to rent a Harley this time and head out. I am not one for the Casino's but I really like the outer areas, beautiful. And you guys seem to have a lot of places to go shoot.
