I have a USED all aluminum complete "minus the Spring and Buffer" bushmaster old style 3 position tele stock with a B on the left side near the latch assy, it is still in Very Good condition !!
I'm wanting to Trade this for a Colt Marked Bolt , MPC or MP , in new or excellent condition , you can IM or EM me if you have one, Thanks , Ken
Update here : I have pics if anyone is interested in the stock, a couple of the treads on the bottom of the buffer tube are wore off some but should work fine , and also shows the usual wear from opening and closing the stock !!!
