| A2 rifle buffer length versus a 6 possition collaspsible buffer? Which is which? |
|
The A2 buffer is a smooth round tube with a shoulder behind the threads. It is screwed all the way into the back of the lower, thus capturing the buffer spring and detent. The rear takedown detent and spring are captured by the buttstock, which is held in place by a screw, which goes through the butt into the rear end of the buffer tube. There is a projection on the buttstock which insets into the rear of the lower, aligning the stock vertically. A2 buffer tube is actually a misnomer. A1 and A2 stocks use the same tube, but the A2 has a spacer installed behind the buffer tube to accommodate the longer stock. A CAR type buffer tube has a projection on its underside with holes in it for the buttstock to lock into, giving you from 4 to 6 positions on most CAR buffers. CAR buffers need a castle nut and receiver end plate for installation. The buffer is screwed into the rear of the lower just enough to capture the buffer detent and spring, and then is secured by the receiver plate and castle nut. The receiver plate will align the buffer/stock vertically and retain the rear takedown detent and spring as well. A CAR buffer is best installed with a CAR wrench, but the A2 type only requires a large flat blade screwdriver. |
