I'm pulling together some ideas for my first pistol build, and what I'm thinking I'd like to do is use the buffer tube from an A2 buttstock (and just the buffer tube -- not the stock). The only thing which I'm concerned about is that with an A2 buttstock, it is the buttstock itself which holds the detent and spring in place for the take-down pin. My initial thought is that throwing on a plate like what exists for the collapsible buttstocks will work, but even though I can file down the little "notch" on that plate so it will fit over the round tube, is there sufficient threading on the A2 buffer tube to hold the plate in place, and still capture the buffer retention pin? Any help or suggestions would be greatly appreciated! _MaH |
Well, now that I think about it, I'm going to need more than enough thread space for the plate, I'm going to need space for the castle nut as well. Otherwise, that buffer tube could shake itself loose (excluding the use of loctite). Seems like I might have to use a different tube - either one from a collapsible stock, but lose the stock (whole constructive intent thing), or remove the rail on the buffer tube so the collapsible stock won't be able to attach. Frankly, I'd rather avoid that and, if an A2 tube won't work, acquire something else from somewhere. _MaH |
ok, after reading the above I am confused, I know a a2 doesnt use a castle nut... Just tap the damned hole. |
Castle nut does more than just hold a plate that holds a detent and spring in place, it holds the whole damn buttstock assembly in place. So ignore the "tap the hole" solution -- that fixes the detent & spring but not the buttstock. If I use an A2 buffer tube without the actual stock, there's nothing (excluding the use of loctite) which will hold that tube in place. After firing a few rounds (perhaps even one), it could rotate the tube causing the retention pin to come loose, screwing up the action, or even worse cause the damn thing to fly off. But if I could apply a castle nut, it would hold the tube in place. _MaH |
