Mag problem?

[DirtySCREW]

...so...there's this guy I know....who got an 80% lower and milled it out. He slapped a PSA complete upper on it and called it a day.

Today, when we tried shooting it..it kept stove piping. Every round. Then it shoot 2-3...then back to stove piping. We were using a Magpul mag. We switched over to a metal C products mag... same issues. It felt like we had to really "slam" the Magpul into the mag well. Had to seat the c products one real good too...but the Magpul felt like extra effort to get it seated.

Finally it would shoot 7-10 rounds with out jamming...then it jam again.

Ammo was Wolf 5.56 and .223 steel case.

Do you think there is a problem with the 80% mag well or do you think it's an ammo problem?

My PSA AR (PSA lower/PSA upper) eats wolf ammo like kids eat Pez candy!!!

What say ye?

Also... might be a dumb question....but how do you "sight in" an AR back up sights? Where do you start for yardage..50? 100?

It could depend on what you’re intended use is.

I’d guess most would either do the 25/300 or 50/200 distance. Get it sighted in at the shorter then confirm & dial it in at the longer.

I guess I'm also asking of the sight picture for AR.

My ARs have red dots of some sort... haven't shot much on irons on ARs.
The sight picture is supposed to have the "peg" ( forgive my terminology ignorance) of the front sight in the middle of the peep hole... Correct?

I can't help him if I need help too...lol
