KEVLAR LOWER PREPRODUCTION SALES

IT’S OFFICIAL! 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. In fact, we are still finalizing the design.

It is not the same  lower that seems to be floating around everywhere. This lower is a Kevlar reinforced 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
- Color will be black.
- Finish will be a textured pattern for positive grip.
- There will, as always, be no markings or logos or serial numbers

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.

We are not taking preorders now, unless it is a bulk order (more than 100 pieces).

 

 

SHIPPING NOW! THE BEST JUST GOT BETTER! Our AR-15 drill and mill jig now features countersunk screw heads on the side and guide plates. Why? Some customers have drill presses or mills with short chucks, making it more time consuming to work around the screw heads with short mills.  Coming soon to our AR-10 / .308 jig too!
