Its about the best dissipator kit but rough around the edges. - Del-Ton Dissipator Pre-Ban Heavy Profile Rifle Kit

For the money its a really good kit but be warned not every part is mil-spec and will require some hand fitting with the lower you buy. Also be warned you might get a bcg that won't cycle. The bolt and carrier that came with the kit I got was so out of spec to where it wouldn't cycle and grinded on the walls of the upper receiver. Del-ton make it right by replacing it but it's an issue you may have to deal with. But for the price you really can't beat it if you want a cheap dissipator set-up.
