Hey guys, first off, i'm a complete newb with ARs 
Here is the situation; I have a factory built, stock RRA rifle. Had around 400 rounds down the pipe without a single hicup. Everything was P-E-R-F-E-C-T. Than, 3 weeks ago, the mall ninja in me decided to change the stock (and buffer tube, which is around 0.20" shorter, problem?). Here is what's happening now:
-Bolt isn't locking on empty mag (rifle cycles fine)
-When manually opening the bolt gently (with bolt release button), it stays locked but a single tap on the side of the receiver or putting in down on the bench without super dupper extra love and it closes
-When inserting a mag w/open bolt, if I use the bolt release button, the bolt rides OVER the first round instead of bringing it home. When closing the bolt with charging handle, everything is smooth...
Things I have tried:
-I checked the buffer tube to make sure it held the buffer retaining pin correctly and it's fine
-lube the hell out of it, everything in the upper was super dry (didn't solve anything though)
Things I haven't tried but that might help:
-other mags, only have one right now... (I spend too much on pistols and ammo
)
-changing the bolt catch
-selling the rifle for 200$ and buying a norinco SKS
Fun fact: when doing rapid fire, bolt stays open on empty mag, I would say 80% of the time.
Any other tips? Thanks for your time, greatly appreciated.
