| A buddy of mine just bought a commando stlye Bushy new about 2 weeks ago. Last weekend he went out to the range to test it out. Every few rounds he fired it would jam a casing on ejection. This was with three different types of ammo. He went home gave the rifle a good cleaning and went back to the range the next day. Same thing happened again. So he went to the dealer where he purchased it. They told him to leave it and they would fix it. Today he went to pick it up and they told him nothing was wrong. They said it just wasn't broken in yet and needed to be heavily oiled. They fired about 30 rounds for him and it didn't jam. Is this true or are they blowing smoke up his ass? I am no AR expert but I had a Bushy that I bought new a few years back and it had not a single problem EVER with any kind of ammo I ever fed though it straight out of the box. Even wolf. Thanks. |
| Sorry I cant really describe the jam any better. Being that I didn't see it myself. He just told me that the casing would get stuck in the ejector after about 3 rounds. I will tell him to register here and describe it better. I forget what ammos he said he was using but they weren't garbage. I think Remington and Winchester and something else. No Wolf. |
| He may need to dissassemble and clean the bolt, the ejector in particular. On my new Bushmaster the extractor had a little tiny burr left over from the machining process making a sharp edge and while shooting it was scraping tiny brass particles off the casings. Some of these may have worked onto the ejector pin, causing a bind. I deburred my extractor using a fine nail file, very carfully so as to remove only the burr. The amount of brass shavings in the bolt area has dimished significantly. |
Which is one of the reasons I build my own ARs, and put Colt bolts in all of them. None of the aftermarket bolts I've found are as smoothly finished as the Colts. Bought a Rock River bolt once, and the edges were so sharp I actually cut my finger when I ran it around the edges of the bolt face. It's a very competitive market out there these days, so the aftermarket guys play the odds I guess, and cut out a step or two along the way to save a buck in production costs. I'm sure the materials and machining are good on all the major brands, but if they can eliminate a polishing step after machining, and count on use to knock off the sharp edges, it seems that's what they will do.  In most cases it seems to work out OK; but sooner or later somebody gets a piece where those knocked off edges screw things up. That's when the dealer tells you that you have to "break in" the rifle. Does anyone here seriously think that Colt and FN fire their production pieces for the armed forces enough to "break them in"? Or that they need to?  Funny. I only see, or hear, the "breaking in" term used with aftermarket units.  |
