FORTIS MFG Light Weight K1 Castle Nut and End Plate Black/FDE

The K1 LE castle nut and end plate is a major update in the design of the AR-15 Stock assembly. Allowing you to attach a standard carbine buffer tube without the need to stake the castle nut the K1 system virtually eliminates the risk of your castle nut backing out. Constructed from 7075 T6 aluminum this castle nut end plate combo will be every bit as durable as standard GI parts while remaining ultra light at only 16.8 Grams. Adding to its versatility this endplate also includes a 360 degree rotating QD socket for sling attachments. This product is made to precise standards here in the USA.
