Ar 15 issue

[BigTex.308]

I'm with Tommy. Sounds like a gas or buffer issue.

Buffer.....gas problem would hang up more than 1 in 5 on brass.

x3 check your alignment and make sure everything is installed. I also like to break in a gun with good ammo regarless. Then switch to the cheap stuff for plinking

[webstertroy]

how do you check the alignment of the gasstube?

Not completely true. I ran 200 rounds of steel case Tula through my AR on day 1 and had zero issues. I have an RGUNS upper and a new frontier poly lower. I would lean more to the BCG or ramp being the issue.

I have ran I don't know how many rounds through 7 or 8 different AR's and had jams every single one and all different brands makes and configurations. My bushmaster does not like them at all. Only thing that will eat it is my Glock 23.

its what ever came with the lower

when you get home tonight, crack that puppy open and look on the end that is facing you. should be blank, H, H2 or H3 on it. we kind of need to know this, and i still think its possible the FSB is misaligned.

I had same think happen to on one AR the gas tube hole in the barrel was slight off center was not getting a full charge of gas so sometimes pick up and sometime not. Had to adjust the fgb a tad to the left for mine then worked great just glad it was a low profile block.

yeh you are getting covered with posder residue because steel cases dont expand to fill the chamber like brass does.

I know a lot of folks will disagree but I would never shoot steel out of a AR. You typically get what you pay for with ammo also. Buy cheapo steel case, get cheapo results.

IMO, steel case is probably fine in pistols and no AR 15/AR10 guns.

Both of my Colt ARs eat the cheap steel stuff like candy.

switch ammo

[webstertroy]

I have used brass and steel ammo

my guess is that the FSB is off center/not installed correctly.

I had the same thing happen on a custom built gun. I did not get the gas block down tight .....

everyone one of my ar's runs steel ammo fine. try a diff lower if you got one that runs fine and that might help you rule out if its the buffer/spring. if its not the buffer/spring i would think its a gas issue.

Im going tomorrow to shoot again Im going to use buddies upper first on my lower and see what happens and then going to try my upper on his lower...

[Tommyh]

shoot your upper on his lower first when you shoot. make sure you oil in the bolt itself where the two holes are under the dust cover
