Rainier barrels are meticulously designed and machined by precision gunsmiths. Our barrels are turned the same way true artisans have made premium rifle barrels for over a century. Each barrel has hand-cut chambers and crowns with the attention to detail that can only come from highly trained human intervention. While most companies strive for faster production time to cut costs, we strive for perfection. There are no shortcuts with our barrels, period.
Review by Atom on 27 Jan 2025review stating High Quality and Very Accurate Ultra Match Barrel
I just purchased the 20" Black Nitride Stainless Steel Ultra Match barrel after seeing how good my friend was shooting with his ultra match barrel.
I was able to get 0. 5 to 1 MOA groups with it at 100 and 300 yards using AAC 77 grain OTM ammo. I also had very good results with 55 grain X-TAC ammo, but the OTM was more consistent and sli...Read MoreRead more about I just purchased the 20" Black Nitride
ghtly more accurate.
I only have 80 - 100 rounds through the barrel and I'm already extremely pleased with it. I feel that it's a very fair price for a very high quality barrel.
I just couldn't stomach spending $600-1000 for a barrel unless I was a pro-shooter. But, I do think it's worth spending up to $400 if you are looking for high accuaracy.
I paired this 20" barrel with a Sgt of Arms 17. 5" Handguard which has a built in full length ARCA rail and it's awesome.
I Highly recommend both. Read LessRead less about I just purchased the 20" Black Nitride

I could not get this barrel to shoot under 3.5 - 4.0 MOA. I was using AAC 77gn from Palmetto State Armory and I also used some hand loaded 77gn SMK cartridges. I tried different gas setting and different spring and buffer weights. I just couldn't find the right recipe for this barrel. Both previously mentioned cartridges shot 1.5 MOA in the origin...Read MoreRead more about I could not get this barrel to shoot
al Noveske 18" SPR barrel. I was hoping to get a bit more FPS and maybe smaller groups with this 20" barrel. Didn't happen this time, but their barrels have shot lights out for me in every previous purchase. Not sure what combination of gas, bullet weight, buffer spring and buffer weight this barrel wanted, but I didn't find it. Rainer took the barrel back and refunded me 100% ASAP. No questions. No problems. GREAT CUSTOMER SERVICE. I'm a long time and all the time fan of Rainer Arms! Also, the Read LessRead less about I could not get this barrel to shoot
