Awesome barrel


Received my order in just 2 days primary arms was great with shipping. Barrel is beautiful completely nitride coated with superior machining. In the hand it feels close to a pound in weight perfect for a lightweight build.

Excellent finished and accurate light barrel.

Excellent light weight and accurate barrel. Add a pinned strike industries checkmate comp and you have just a fraction over 16".

8,000 plus rounds and still going strong.

I have had this barrel for several years now. It has about 8000 rounds through it; I stopped keeping track around 6,000. It is light weight and accurate. I still get MOA groupings out of it when I do my part. Most of the rounds have been brass cased 55gn
<br>223 with about a thousand of Wolf steel cased .223. Most of those rounds are not slow fire from a bench.
<br>I think it is slightly overgassed as I have to run a SpringCo Blue action spring and an H2 buffer to get it to run .223 loads correctly. Full power 5.56 is still a bit over gassed but being as I run it in Alaska I would rather it be slightly overgassed for the winter.
