Rollin, they are not rare. Scarce, perhaps but you can't really say they are rare. No good for the semi guys, open bolt is a no-no for youse. And on top of it, to rape the customer to the tune of $2500 is pretty piss-poor. Figure a parts set is going for about $399, lets say $500 for poopies and smilies. That means he's charging $2000 for a few parts!! Any of you jump on that deal yet?
However, for the full auto guys, I know where the parts to change YOUR A4 to open bolt are. One full set of parts, everything you need to change your gun to open bolt, for only $450.
(standing aside to let the stampede go by...)
Well?
