Does anybody have any experience with these barrels? Midway has them at a great price, but I know nothing about them. Thanks for any input.

I have one from the Liberty era, 1-8 5R 24", Grendel chamber and it isn't a short chamber. It was easy to assemble and dimensionally correct. Shoots about .75 moa with 123 factory AMAX. It's as accurate as my AA Overwatch upper. I am thinking about using it in a precision class.

I bought one a few months ago and I'm sending it back tomorrow. It shot well for about 15 shots and then the jams started. At first it would fail to eject and progressed to failure to extract. I cleaned the chamber, but it didn't help. I installed a heavier spring with an o-ring. That worked well for another 10 shots and then the failures started again. To me, it was a very cumbersome single shot. I will say that it was very accurate. I shot a .33" group at 200 yards. Unfortunately for me, I'm past 60 days so I can't get my money back from Midway. I can only get another barrel or store credit.
The reviews on Midway indicate that a lot of folks have had good results so it might work well for you. But if doesn't, don't waste a lot of time trying to get to work. Just send it back and get a refund.

Originally posted by Stirling View PostThat was my first thought and I checked it more than once. On my first trip to the range after several rounds, I did notice it was loose. I heated the block up with a heat gun and tightened it down. I thought that would solve the problem. It didn't. The next time I shot it, I needed a cleaning rod to remove the shells. That's when I installed the heavier spring and o-ring. I also checked the gas block and tube again. Based on the powder marks around the gas port, it was centered. Plus, the bolt never failed to lock back on an empty mag. So the bolt was cycling fine. It just wouldn't extract the shell at all.

The ones I have seen have a .094" gas port on MLGS 18", which really needs to be tamed with adjustable gas, heavy spring, a heavy buffer, and often a combination of at least two of these things (heavy buffer + adj block).
As long as you go into one knowing that, you can tame the gun. I wouldn't let a .33" group at 200yds barrel leave my possession, and would just tame the gas. That's the most likely reason for your failure to extract issues. Cyclic rate is way too high on a MLGS 18" with .094" gas port. It shouldn't be over .076" really.NRA Basic, Pistol, Rifle, Shotgun, RSO
