I tried to find reviews on these before buying one but couldn't find anything except some useless chatter on reddit. I bought one anyway, left a review on TNA and leaving one here.
This review is for a 10.5" CNA Barrel - 223Wylde - Parkerized finish. The stats can be found on TNA so I won't bore you to death with it.
I bought this barrel to build a budget CQB 0-150m rifle. Once the break in was done (barrel is not chrome lined), I slapped my Bushnell 10x40 mounted on a Burris PEPR to test accuracy at 100m. I used cheap 55gr federal bulk, Remington UMC, PMC Greentip 62gr, 62gr and 68gr generic handloads. I used 5 and 10 rounds group.
UMC gave me garbage groups between 4" and 6". Sometimes the group was 3" but one or two weird "umc" flyers were happening, stretching it to 6".
Bulk Federal 55gr gave me reliable 3" groups.
PMC 62gr Greentip gave me groups in the realm of 2" on a regular basis. Some smaller than 2" groups did happen, between 1.2" and 2"
Generic handload 62gr hornady got me regular 1.5" groups
Generic handload 68gr hornady got me close to a reliable 1" group everytime with 2 sub-moa groups (.8 and .9)
So the 10.5" CNA barrel has accuracy potential for its low cost. 150 rounds were shot for this test.
I did run it thru its pace after break in and before scoping it I ran two CQB course of fire of 200 rounds each. Rifle ran fine with zero malfunction besides the "canadian stopage" due to our magazine laws.
A total of 550 rounds has been fired thru the rifle without clean up.
Overall for the price, this barrel delivers everything you'd expect from an AR15 barrel. It's not chromelined, it was not part of my criterias since this rifle won't see a combat zone and maintenance isn't an issue. I chose parkerized finish because it was cheaper and I'll do a rattle can paint job on it soon.
One more test needs to be done: barrel life ! I'll run an accuracy test every 1000 rounds to see when accuracy decreases.
Great value barrels if you're on a budget or building a "bin parts" AR15. Buy with confidence and thanks TNA for the affordable goodies !
