At least in the 10/22's I've tried about 5 different brands in various guns. Some even had little metal rods in the middle of them (one I'm still using now does). the "tuffer buffer's" I've used have yet to fall apart or give me any problems at all. Their nothing fancy, just a good grade of polycarbonate I guess. When you can get three for $12 there a great deal! I'd guess any brand will wear out with enough use and time, but these seem to be lasting.
I use a buffer in my SKS's as well (
HUGE differance there!) One buffer company makes a little wedge to take the slop out of AR's upper and lower receivers and it works great to. (any DPMS AR I've seen yet is tight as a drum though, and the buffer wont even fit).
I like em!
DJ, next step is to drill a .3" hole in the back end of the reciever. Magnum Research guns come this way. ITS AWSOME! Allows you to clean the barrel properly without removing it from the reciever. Then lap in the contact surfaces on the hammer and sear (do a lot of research on that one for your own safety if you've not done anything like this before!), put in a Power Customs firing pin, and half a dozen other goodies from them, lap in / square up the chamber face, cryo the factory barrel, get a cool stock. THEN you'll start wanting another 10/22 to build differently from the first, and so on, and so on... IT NEVER ENDS!!!!!!!!! It's a habbit you cant kick once you start. And now
its to late for you!

Another one hooked!
