Brownells USA Spent rounds getting stuck 12/08/2018

I ordered 1 barrel received it put the rifle together fired one shot the spent casing was stuck in chamber I had to beat on my charging handle to get it out 3 more shots was the same I tried different ammunition an different bolt a carrier group the 4rth shot I broke my charging handle trying to get the round out I ordered another thinking it was jus a messed up barrel recieved the 2nd one same issues the 2nd one isn't as tight but dang sure gets stuck every shot I'll be sending them both back accuracy was outstanding with the hornady 123 gr black but I can't deal with casing getting stuck if they remachined them I'd give it 5 stars

Definitely recommended

Brownells USA Good looks, great accuracy 22/07/2018

Very well finished exterior that mic'ed to correct specs. Fit and finish is very good. Great accuracy with Hornady SST ammo. Still shot Wolf to around 2 moa. Seems to clean up easy with little scrubbing. Highly recommend. On the heavy side, but that's how you get consistent groups.
