Be very very careful with that aluminum receiver...They tend to blow up. And NO I am not kidding!!!

I appreciate the warning, but do you have a link to any incidences of this occurring with the FA91 receiver specifically? I couldn't find anything on the internet about it. Was this from personal experience? The only thing I could turn up was a problem with some FAL aluminum receiver failures. I've tried to search ARFCOM, but the archive isn't working for me right now. |

A couple of years ago some had problems with these primarily in full auto fire. It had to do with the aluminum seizing the bolt carrier, I think. I don't recall any kabooms, that would seem to be unlikely since the trunion and barrel are steel like the others. So long as the heaspace and bolt gap are normal (sorry I can't help with these issues) and you keep the carrier well lubed then you should be good to go. You might check Springfield Armory about whether the aluminum receivered guns they sold had any issues.

Thanks for your reply! I have gone over this rifle carefully, and with the steel trunion, I cannot see any failure danger, even if there were any electrochemical corrosion between the trunion and the receiver. I fired another 20 rounds through this bad boy and personally am not the least bit convinced that there's anything dangerous about my new rifle. If there's any documentation on an actual failure ocurring, I would certainly appreciate a link. Thanks 'Cheese |

Are you positive it wasn't an aluminum FAL receiver? |

Check the DSA site they used to have some kind of warning on there about Alum rec. Its been a few years ago. Check the FAL Files.com too

Yeah, I have been looking through my search history but I can't find it. I was looking for .308 surplus and it was as a warning from one of those companies. The only real thing is to know that it might happen and be careful only to use good ammunition. I wouldn't worry about it too much - I have seen pics of it happening to Glocks and HKs as well, and I still shoot my Glocks and HKs. I will post it if I ever find it. |

In my opinion, one of the biggest rubs with these rifles is the method used to secure the trunnion to the receiver itself. Two pressed-in pins and epoxy just doesn't instill much confidence in me. YMMV

YMMV It actually seems VERY stable to me. Call me foolish, but I don't feel the least bit endangered when firing this rifle. It hits where I aim and until someone can give me a definite documentation of a genuine problem, I'm calling foul! DSA had a warning on their website concerning some FAL aluminum receivers that had failed. I haven't seen anything other than heresay about the FA-91 aluminum receiver.

Hey, rock on with it. I'd probably make sure I wore glasses when shooting it just in case the naysayers are right.Course, you oughtta be doin' that anyway.
I still think one of the dumber things I did years back was pass up one of the aluminum receivered Springfield Armory HK clones, new for like $900 or $985 in an Anchorage shop. The way I look at it now, I could have shot it til it broke (which they all supposedly do) then sent it back to SA for warranty issues and they send an M1A to replace it, which I hear is their practice with those things. Sounds like a win-win to me. |

Big_Cheese,
If your at all concerned do a search on the forums on HKweaponsystems.com and at HKPro . I've found that some of these guys know their stuff. I know for a fact that some weapons with these receivers have had catastrophic failures,but in all cases someone tried to put a full-auto sear package in them. As long as you watch your headspace,don't plan on converting your rifle to full auto ,and be careful which surplus ammo your using you shouldn't ever have a problem. Also ,I would research it thoroughly before ever using civilian .308 PSP ammo in higher grains. .308 I believe has higher chamber pressures than surplus 7.62 X 51 mm. As always ,don't use Indian ammo or Pakistani ammo. These are notoriously bad . Personnally ,I make it a rule to never buy ammo from places where people bathe ,deficate,and get their drinking water from the same place.Especially if they do it in the order I listed.

My Dad has two of these rifles, had 'em 5-6 years now, and never a problem. I personally think they are uglier than all hell, but he likes 'em, and I guess that is what counts.

I have one of the earlier FA91s-I bought it from SOG Intl. in 1998. I'm pretty sure this was the first domestically manufactured HK clone (the Springfield stamped clones were imported from Greece). For a HK91 clone mine is very well put together-I don't have to pull hard on the charging handle, and it is very accurate. Since I live in MN, there aren't any full auto issues for me unless I get a S.O.T., and even then I would stick to 9mm...I don't have any long-term data for you because I don't fire it that often, but I have been very happy with it so far.

I have one and have never had any kind of problem with it. Someone cut the barrel down to the FSB and welded the brake back on.
Looks weird but shoots great

I guess I've adopted someone's "bastard child" here huh? LOL! I like it, dammit! Until I see absolute, 100%, proof-positive that the rifle design is dangerous, I'm shootin' the beiach!
 Hell, some might think me a dare-devil! Just for a Kicker' I'm gonna be using some of that high quality Indian ammo as well! Heh-heh!

I humbly request that if you ever shoot in PA ,
and are using Indian surplus in ANY semi-auto ,please warn the person next to you on the range. It could be me. I'll want to move down a few slots,and possibly dawn my protective gear. Notice I said ANY semi-auto . Your rifle and receiver should be fine as long as you don't convert them ,drop in a full-auto trigger pack ,or use excessively strong ammo with weak cases. |
