Actually bought 2 of these to replace the 1/9 barrels on my 2 M4gery rifles. They look good, nice crowns but haven't had a chance to shoot them yet.

amazing barrel but the main thing is primary arms shipping i cant get over how fast they are . i find my self getting frustrated with other websites because none of them can ship like pa. all i can say is customer for life!!
Very Nice Barrel!
At first I almost lost it when I opened the box and on the outside of the packaging it said it was a Mid Length Barrel... Not that I have anything against Mid Systems, but I'd ordered the carbine gas tube. So thankfully when I opened it up and saw it was a carbine length, i was very happy! My question is this though, did the person who packed my order know it was mis labeled, or did they make a mistake and send the wrong one only to end up being the right one? I guess some things are unexplainable... Anyways, awesome barrel!

Barrel looks good, haven't gotten a chance to shoot it yet so I can't give any statement as to accuracy at this time.

by John Keoasa
Fastest shipping and it is a very great barrel for the price. Fit right up and it had a lot of oil all over the barrel in the package that it was in

First off, great shipping from primary. They got this to me in only a few days. I love that they have a real time inventory, so you know your not wasting your time looking at something, only to find out they don't have it. And I checked around, prices can't be beat here. Thanks primary arms.
Great experience with Primary Arms! This was my first order, and I received it in 3 days. I will definitely buy from them again.
Very nice barrel
Great finish, no problems installing. Still need to shoot it.
