F-1 Firearms 80% Skeletonized Lower Receiver

7056 aluminum with Jig & Bits – Raw

F-1 Firearms 80% Lower Guarantee

80% percent lowers have their challenges so F-1 Firearms will offer two programs to assist with that:

FUBAR Guarantee: If you mess up the 80% by over drill, over mill, out of alignment, mail in your FUBAR lower, and F-1 Firearms will replace the lower for a one-time discounted price. Contact F-1 Firearms at www.f-1firearms.com for the form to fill out.

80 to 100 Plan: Agree you thought you were a bad ass machinist but are not and return your 80% lower in the same condition we sent it to you and we will send you one back milled to 100%, serialized, to the FFL of your choice – Note these returned items will require you to pick them up from an FFL (Federal Firearm License) dealer / location.
