Poly416 Lower Receiver

NOTE: Hand work is required to complete this product! Read the paragraph below for clarification and see images in gallery. This part will give you an H&K 416 lower with integral buttstock assembly. Just supply the parts kit. The rear takedown pin detent hole has been rotated 90° and is now retained by the pistol grip. The pistol grip now uses an M6, #10-24 or #12-24 helical insert (1/4" inserts cause bulging in the material and weaken quickly). "Chase" all holes with their respective drill sizes (see image in gallery, hole diameters boxed in red). Printed holes are almost always too small so verify you have the correct drill size for helical inserts and not for a straight tap into the printed material. Ambidextrous magazine and bolt release are included, print these on an oblique angle at 100% density to maximize strength.
