Endrin mcarbo makes some great products for the kel tec I got the cover for my stock that made a big difference. Everybody thinks kel tec is junk but watch a guys smile when they shoot a sub 2000 first time that is priceless. I have a quick disconnect on my riser so I can take off my strikefire red dot so I can still do the fold in half thing. Mine is a glock 17 model I have put 1000's of rounds through it have had one failure to feed the first time I ever charged it I did not let the bolt slam shut. So yes it is a great carbine and a blast to shoot
