NEW PRODUCT ANNOUNCEMENT – DATUM GEAR KEVLAR POLYMER 80% AR-15 LOWERS! The response has been overwhelming – thanks to everyone for letting us know this is a product you want. This is a Datum Gear design, created by our own engineers.
It is not the same “freehand” polymer lower that seems to be floating around everywhere. This lower is a Datum Gear branded, Datum Gear designed Kevlar reinforced polymer lower that is the same pattern as our Colt-pattern billet lowers. There are minor differences for molding, but they will work in our own jig or any jig that takes a Colt pattern lower.
- A stainless steel threaded insert is included for the grip screw; no tapping your own hole
You WILL need a jig or other normal milling method (like with a billet lower) to finish our Kevlar polymer lower.
I know what you’re thinking: “Hey, the competitors say you can just mill out the white plastic with a Dremel. Why can’t I do it with the Datum Gear lower?” Simple – we do not believe that it is possible to get consistent, tight enough tolerances to allow that type of lower to be at the same quality level as our billet aluminum lower. And we want our customers to be delighted with the end result, every time. So we strongly recommend using a jig.
