View Full Version : DSA SA-58 Cycling problem

February 29, 2008, 11:23 PM
Need Help, Have a DSA SA58 that has cycling problems. Have tried different ammunition-commercial and my own reloads which I believe is not the problem. First, following DSA's own Gas port adjustment instructions, starting at lowest setting, the bolt catches the case sideways (not expelling the brass all the way). As I asjust the gas ring 2 clicks each time to a lower setting hence more gas to the system, the rifle intermittently does not fire. Upon investigation, the primer has a tiny firing pin strike on it. Appears the hammer is falling as the bolt carrier goes forward after cycling the previous round. I simply pull the bolt back and expel the unspent round and the next round will fire. Occassionally the rifle burps off several rounds full auto. Is this the indication of a worn or tampered sear?? I bought the rifle from a gunshop in Arizona. DSA sounded suspicious and indicated the rifle might have been tampered with and if so they would confiscate it if I sent it. The Rifle had previously been released by the ATF so I don't believe the rifle has been tampered with. Any help or comments would be appreciated.

Confiscation should only apply only if someone intentionally tampered with the gun for the purpose of making it go full-auto. The BATFE probably obliges them to report and confiscate such weapons, after which they probably pay the owner an unpleasant visit. If the gun is your legal property, they would have no right to confiscate it otherwise, as that would constitute theft of legally owned property. Of course, you could well wind up in an argument as to whether the tampering was for legitimate or illegitimate purposes, which there is a good chance you would lose, since they are the presumed experts regarding their own guns.

I would inspect all the trigger group parts carefully for signs of grinding, filing, polishing, or other tampering, and get and install replacement parts for anything that appeared to have been tweaked or has significant wear marks. That should stop the hammer following you describe. I would also look at the bolt and firing pin carefully.

If you find no sign of tampering or wear, getting the factory technicians to look at these parts makes sense, though at this point I would not blame you for avoiding dealing with them. I would see first if you can find a gunsmith in the area familiar with these weapons? If you can't, I would ask the factory if they would just inspect the trigger group parts and bolt group and verify that they appear to be OK? Then talk to them again about the problem and see if their attitude is any more cooperative?

Thanks for the advice. I'll do exactly that. I don't believe it had been tampered with but I'll seperate the receiver from the lower and check it out. I'll post with my findings. Thanks again
