Anyone try a black dog machine 22 conversion in a full auto m4? The description says ar15/m16 type rifles but does not really make any other mention of full auto fire. I went ahead and ordered one and extra mags before the new law takes effect restricting mag size. It may be a while until 22 ammo is plentiful again but when it is it will be a lot cheaper to take friends out to do some dirt blasting.
