Great product, great look!!!! - CMMG, Inc Receiver Extension Kit, Pistol Length

So i was looking for something that looked good without having to get a brace at first as they can be costly. this product is it! very nice look, and the feel is even better- the knurling on the back half is very nice. this doesn't include a castle nut (designed that way), so i would recommend some locktite when installing. other than that would highly recommend. side note---- i compared the size of this to a KAK buffer tube and the KAK is quite a bit larger, so if you are planning on using this with a shockwave blade, dont get this - get the kak one. however this is supposed to fit like a glove with sig brace and SB tactical braces hence my purchase.
