UPDATE:
Ok I got the little guy to work again. I think. I only put 30rds (xm193) through it but so far so good. I replaced the ejector spring. The old one was very dirty. It has some waxy skin hanging off it (CLP residue?). I also replaced the extractor spring with a Wolf x-power unit. The Wolf one was a little harder to put in because it was a little longer and much stronger. I think the real problem is was with the ejector spring as it was just really messy looking. With the few rounds I shot I noticed the brass was defiantly hitting the brass defector, because the brass was going about 45 degrees forward and to the right, 6ft from the gun when standing. I also bought a Wolf x-power spring because I thought the bolt might have a little too much rearward velocity but I have not put it in yet. I look forward to putting a case of wolf through this little AR again. Thanks for the help all.
Hey. I am stumped here guys and don’t really know what to do. I have posted this problem a few times but have gotten nowhere. So here it is again. I have a Bushmaster 16” lightweight upper on a Cav arms lower. I had put maybe 1200rds through it without a hitch. Now all the sudden the thing is really messed up. I don’t get it, I have changed nothing but yet the rifle has changed on me. First off the A2 sights are now mysteriously off at 100yds by over 6”. I have I have checked all the knobs and adjustments multiple times but they are the same as they were whey I first sighted the gun in over a year ago. I have re sighted it in but I am clueless why this happened. Second the gun now jams frequently, on the order of 1 or 2 times per 20rds. All jams have been failures to eject. This I also don’t understand this because all parts function as they should as describe in the trouble shooting guide. The ejector spring is as strong as my other ARs if not stronger as is the extractor spring. I initially thought it might be short stroking but that can’t be the case because the gun locks back on an empty mag every time. Also this rifle has loads of recoil; I can feel the buffer slamming the end the receiver extension every time it fires. What the heck is wrong with this thing? It shot like a dream for the last year and now it is a peace of crap.
Bullet in pipe, brass caught by bolt.
Ditto, but brass is fliped.
Bolt locked back on an empty mag and brass just did not fly out.
