from what iv read in a few minutes they make cheap lowers and well complete guns, but are a ok or some said very good quality. Im guessing he bought the stripped lower and had the trigger job done and put the bcm upper on it. Im now alittle worried, my guess is he bought it this way or had it built. I guess worst guess is a swap out the guts of the lower, but im betting its good to go. I cant get a scope or sights for week or so till I get back from indiana, so gonna be a fun wait. lmao imma bet my self if I bought a janked up ar knowing what I know and not shooting it before hand. my fault though, just like him not driving the truck that had 350000 miles on it, so I figure rebuild the lower is better then the day that engine went plus I had no use for the truck any more

Other than fit to the upper, problems with lowers are usually a pretty easy fix. Problems with uppers are generally more complicated and not always a cheap or easy fix.
Before I'd go modifying gas blocks and such, I'd get a feel for the rifle. The time to find it doesn't shoot for a hill of beans isn't after you've invested even more in it that what you already have.
I have no complaints about PMAGs, other than they're a little pricey. If you're proficient with mag changes, you don't need to worry about gimmicks like windows that tell you how many rounds are left. The spring and/or the follower are often the culprits when mags fail. Really cheap mags will have sheet metal problems, too. But generally, most GI mags will work just fine, provided you don't leave them loaded with 30 rounds for long periods of time or let them get full of dust and gunk. We didn't have PMAGs when I lived among the Kalashnikovians, GI mags worked just fine for me.

True when we had our bushmasters heck 10 years ago dam im almost 30 lol we had 6 mags two new mags that came with our bushmasters 4 surplus gi mags. Never had a issue with them. We left ours loaded 24/7 (I knew less then then I do now). Still no issues. Iv never cared much bout round count though either. Prob just go with whats price best I did find the magpul plastics for like 14 bucks I think it was though. Im more concern with feed issues then plastic or steel so might buy one plastic and see how the do. My buddy bought cheapo plastic for his ak47 while he had a 1-2 round ftl with his steel the plastic would ftl or ftj bout 3-5 rounds per mag but that ak was a pos he traded it for a nice 2000 dodge 1500 lol

Not saying there's any reason to not replace the gas-block, but having it in the way of a scope isn't a valid issue. Flip up rear sights are quite often the same height as the A2 carry handle sight would be, so they'd be compatible with the fixed front sight. As others have mentioned, occasionally you can get yourself in trouble by mounting the folding front sight to a flat top gas block, because it's shorter than the handguard rail that the folding sight was designed to ride. The solution is to use a sight riser, or an extra height gas block that mates up to the height of the handguard.
Interesting to find out it's a DSA Lower. I wouldn't buy one myself, but as others have mentioned, all you really need for an AR to shoot well is a good barrel and a good trigger, then the rest is just a matter of having a good smith fit all of the parts together to feed properly.
