KIT notice as of March 1st 2020.

All build kits are subject to change slightly in this time of EXTREME demand. We are not currently able to fill specific spec requests.. the kit parts will fall into the general specs above but items such as stocks, handguards, and muzzle devices are changing daily.

Due to extreme order volume the handguard may NOT be a quad rail.. it will be either a quad rail, mlok or keymod depending on availability.  You can still attach rail sections to mlok and keymod for your accessories

    This kit is my 2nd purchase, the 1st was the 7.5” stubby build & that build assembled effortlessly! I’m certain the 300 will also go just as smooth in both the build & operation! Hats off to Team Durkin for their supply during the demand as well as the shipping time! I ordered this kit on a Sunday, and had the kit in my hands on Wednesday!! I’m stoked and can’t wait to send a bunch of rounds down range with this piece!! Looking forward to many more purchases in the future!! Thanks a lot!!
