Ratings & Reviews
Supreme Quality and Accuracy.
by Thomas In WA
I built up a plinker AR15 with this barrel. It is insane quality for the price. With a little over 1200rnds through it now, it is turning in consistant 2MOA groups at 100yds with a non magnified Vortex StrikeFire.
This session was shot today 10/26 in 50degree downpour rain,at 100yds, sandbagged of cement shooting table, for 90rnds I had a consistent 2" hole in the center of the target with a few flyers outside of that.
With a Burris 3-9X40AR scope it is turning in 1/2 MOA groups. Both sessions were shot with the same lot of Am Eagle 55gr FMJ red box.
This session was shot July 9th in 75 degree weather sand bagged off a cement shooting table.
I have other "Premium" Ar's that don't shoot that consistently
You cannot go wrong with this barrel, for quality.
I have two more in storage for future builds.
Excellent barrel with good ammo
Like this barrel really well.Shoots 1/2" moa at 100yds with 55gr austrailian outback ammo.3x9x50 cheap tasco scope on ar15.
Hard to beat for the money and accuracy!
Looks great. Fits perfect. Headspace is good to go. Can't wait to shoot it.
Perfect for my budget build, nice quality.
Very nice barrel, great price. Fits perfect with my Anderson upper (purchased here on sale). Fast shipping. A+ for these guys.
Scuffed exterior; Not a beauty queen.

I had to double check my order because both barrels i received were scuffed up and i thought maybe id purchased a blemished item. Nope, they just looked like they had been used in a build. The barrel was at least clean and looked straight.
ANDERSON MANUFACTURING 16″ M4 CARBINE CONTOUR BARREL CHAMBERED 5.56 WITH A 1-8 TWIST M4 FEED RAMPS
by Tights -
Nice looking barrel. Snug fit in a Anderson Mfg. stripped upper. No complaints, Just finished build, and I have yet to be able to get to the range to be able to report accuracy. To be completely honest, if it couldn't hit the blind side of a barn I would still be happy with it because it went on my first complete build!

Just getting mine broke in and it's way more accurate than I will ever be and as always great price and service from primary arms love this site
The One To Buy
by Mark -
I used this to build a rifle. It has performed beyond my expectations. Accuracy has been ridiculous for such an inexpensive barral. It is now my favorite rifle. ans i have some high end rifles. LWRC, Knights A, JP, HK. Do not hesitate to buy this barrel for a build.
Spend the extra money
by Dylan -
The headspace was horribly off. Three gunsmiths said I could not use the barrel.
NOT WITHIN SPEC
Just checked the headspace on this barrel, unfortunately it is not within spec, not usable at all. Got this barrel practically for free as a bundle....now it's just a nice paper weight.
