| Review: I bought a complete 18" stainless PA10 upper from PSA a few months back, then bought a complete billet lower a couple of months later. When I initially tried out the resultant rifle, it suffered multiple feed problems - perfect function from the left side of the magazine, but almost 100% FTF from the right. I tried a couple of different magazines and 3 different types of ammo with identical results. I sent the entire rifle back to PSA for service/replacement. My original 'repaired' rifle was returned yesterday and functions the same as before - almost 100% FTF from the right side of the mag but perfect function from the left. It appears that PSA did nothing to the rifle - just boxed it back up and shipped it back to me. I've never had a rifle of any kind simply not work out of the box before, and I've gone through a LOT of them. Completely unacceptable. |

Is it a gen 1 or gen 2? Are both upper and lower the same gen? Â Did you use PSA parts kit and BCG? What buffer/spring? What magazines are you using?
It could very well be out of spec parts or part comparability issues or magazine issues. Some people have had problems with Magpul magazines.  I have a gen 1 that functions flawless. Everything is PSA except the Magpul PRS stock. I'm using a rifle buffer on mine.  I am also using 20 round Pmags. |

It is not a dynamic operation (gassing) issue - I can generate a failure to feed by dropping the bolt manually from locked back or even slowly sliding the charging handle forward. I suspect it is a defective upper receiver, but see no reason why I should be screwing around with it. I didn't buy complete assemblies to give myself a science project. I'm POed. |

Not just the PA10, lots of teething problems with these 30 cal builds.
Expensive paperweight or figure it out yourself. My factory DPMS 308 was a finicky bitch. Not even sure which tweak fixed it, but it runs now. Might even be a break in issue. I know you said you didn't want a science project, and I would not send it back again. Lube the hell out of it and try some different mags. The steel DPMS mags have been good to me, and are pretty cheap. I have had to bend a feed lip on one to get good function. |

Mine had an improperly angled chamber ramp so it wouldn't feed correctly, it would fire the first round no issues, but the next round wouldn't feed in and would get gouged by the bolt. I tried it with 3 separate mags, diff ammo, finally called PSA and they gave me a free shipping label, no questions asked(despite having the upper for a year before buying a lower and firing it). Sent it back, 2 weeks later and it ran like a champ, was heavy as could be though. |

I suspect mine has a similar issue - bad upper. They sent me a shipping label too, and I sent it back, but there is no change in function - still doesn't work at all. I'm pretty sure they didn't do anything. I'm willing to try a new rifle, and requested that or a full refund including FFL fees. Quoted:

Yep Lancer and quality ammo, then move from there. In my opinion Magpul really needs to be avoided in the 7.62 unless you know for sure your rifle will run them, and damn sure dont use them if your having feeding problems and trying to find the solution. Actually I think I remember reading PSA said if your using pmags that only the gen 2 pmags would work??? or something to that effect. Just found many links on this through the giggle
click And this thread was there as well click |

There is a video (I refuse to link it, because I think he's a clown) by James Yeager showing the difference between 7.62x51 mags. Apparently, Magpul sets their feedlips lower than some others (which can cause issues on some rifles). They said Lancer L7's had the highest feedlip height and only recommended THEM (as they, too, had issues with Pmags for the same reason).
There is also another thread somewhere where someone had the same exact issue as you and IMI Defense 20's solved that issue (I guess they, too, have a higher feedlip height). Personally (as said before), my G1 has zero issues (have not fully built my G2 yet) with either Pmags or IMI's, but you may want to look into getting L7's or IMI's and see if that resolves it (since Pmags seem to be the lesser of all 7.62x51 mags). Doesn't surprise me, Lancer kicks MP's butt with their L5 series, and apparently does it again with their L7 series. IMI's, AFAIK, are only sold here through Aim Surplus (where I got mine. Windowed 20's @ $16/ea). There are a LOT of guys like me who love them, so they sell out VERY quick (as in... hours), so get on the "notify" list and order QUICK when they get them. Keep us posted how your situation works out! |
| Are these PSA rifles that much cheaper that you would not just buy a proven quality rifle for a little more money? I know there are lots of AR 308 or AR10 rifles that can cost over 2500.00 but I kept it simple and for 949.00 the Armalite AR10 DSR works excellent with all types of ammo. |

There are GREAT deals to be had with 7.62 nato AR's... but not if you have specific parts you want on it (for instance, good luck finding a factory ar10 with a nitride pencil barrel, adjustable gas block, and ambi CH). Just as with AR15's, most (ok, many) people prefer to build their own so they get exactly what they want (and because it's easier and cheaper) rather then settle for what the factory offers. |
| My Gen 1 runs like a champ with P mags.........I'm not a big fan of Pmags...........But this rifle has about 500 rounds through it with only one hiccup on the third pull of the trigger. Factory Hornady, Remington, Winchester, bunch of that Turkish Ball from Walmart and my reloads......................With that said, if you read these forums, all kinds of problems with all kinds of firearms..........I had issues with a barrel maker that is always on this Forum, Chamber cut too deep..........With that said I didn't bash them, even though they were not much help at all....... |

I wanted a 'knock around' 308 AR. I have an RRA LAR8 X-series which is 100% reliable and a total tack-driver. I just wanted a cheap beater, though I ended up with a really expensive paperweight. PSA haven't replied to any of my emails since I got the rifle back, BTW. I just got my PSA - 10 and am looking forward to shooting it this week. I wanted a 7.62 gun that took "Standard" magazines, so I rolled the dice on this to see what would happen... |
| I have two of them. One was an early one that would not feed and lots of FTE. Sent it back and they sent me a different upper. Now I am very happy with both. One of the two is way more accurate than I had anticipated it to be. I have put together a 6.5 Creedmoor and a 358 Win using PSA uppers and they both run great. |

Built both of mine from scratch, sourced parts from eight different manufacturers, both run like tops. Then again, I studied a bit before just throwing parts together. Go figure. |
| I bought my "used" but unshot. The guy built 4 with his brother in law and they decided to sell 2 of them. Â I had the same feed issues that people seemed to have with the gen 1s. I changed the bolt with one from Midway that was on the compatible list and ordered the orange buffer spring and it runs like a sewing machine now. |

Yep. I as well. I've been in the 308 AR game since 2003-04 ish. Just gotta know what's what. Quoted:

Well, it's on the way back to PSA as we speak - they did finally get back to me after a few days and sent out another call tag. I attached a more verbose description of the problems - hopefully it'll come back running. |
