  • Price point is awesome

    I haven't fired using this yet so I can't attest to the buffer tube assembly (which seems well made), but the fit is sweet. I actually enjoyed putting this on with how it connects. It's easy enough for a chimp to do it (ME) and looks and feels tough. length of pull was almost the exact same as the m4 telescoping rattle box is when fully extended. If you want to get rid of a rattle trap and have something with a fixed length and not spend a fortune on magpul which everyone else has, it's this. The lower was a ruger 556. (at least the shell of one)

  • high quality, easy installation, no qd sockets

    Would have been 5 stars but the skullaton model does not have qd sockets installed just the holes to install your own.
