Description

The Fortis Manufacturing Lightweight Enhanced K1 Tapered is an end plate and castle nut assembly for the AR-15 buffer tube, finished in Flat Dark Earth. It is designed to attach the castle nut to the end plate without staking, using a tapered fit intended to seat and seal the nut in place.

The assembly is machined from 7075-T6 aircraft grade aluminum with a Milspec anodized finish and weighs 0.55 ounces (about 16.8 grams). Per the retailer's listing, it is ambidextrous and uses a 360-degree rotational locking interface. The manufacturer's stated installation method is to tighten about one quarter turn from hand tight, and if a torque wrench is used, to stay within 15 to 20 ft-lbs.

The package contains one end plate and castle nut assembly. The product is listed as compatible with the AR-15 platform.
