Comes with everything you need for a nice front-end look on your m4/16, except for shims/o-rings to make the outer barrel fit properly. After figuring out how to install it all (didnt take long, just no instructions with it) the outer barrel would move the slightest bit and allow the inner barrel to move around too. (not good) I found that even after tightening the delta ring down all the way it wouldn't seat all the way against the outer barrel, I fixed this by using two o-rings on either side of the outer barrel flange and it works perfectly now. Another reviewer mentioned his coming with pins, there wasn't any pins in my kit but I do see where there is a spot for a set-screw to hold the outer barrel from rotating (my kit didnt have the set-screw either) but after I added the o-rings, this wasnt a problem anyways. So, all-in-all, a pretty decent kit for a good price.

this is a good product great quality peices but it doesnt come with any instructions on how to install it but its pretty easy to figure out this kit does not come with an inner barrel but a 300mm inner barrel will work just fine overall I am happy with this kit and it is very well priced for the quality.

This rail works great, however you will obviously need a 300mm inner barrel for it. It does not come with instructions but pretty straight forward. It does come with 2 pins that i have no idea where they go and its probably why the free float barrel is rotating after everything is screwed in tight. Instructions/Manuals are very hard to come by.

i was thinking of converting my m4 into a cqb rifle but i dont want to loose to much barrel lenght so can i use this conversion kit but use a different mock silencer?

Webmaster: Yup. Anything 14mm negative / counter-clockwise will fit. As long as it is not TOO FAT.

Does anyone know what the inner barrel length for the set would be?

Webmaster: The set does not come with inner barrel. Its CQB-R length. 300mm.
