Solid part - Bravo Company MFG End Plate with QD Socket For AR-15

A quick attach receiver end plate might not be necessary for most shooters, they do look better than a standard plate. the Bravo Company plate fits flush, no gap, secures qd without a bunch of wiggle. don't have to worry about anti rotation in this location because the sling ring ends make contact on the ends with the buffer tube and can't swivel. I prefer the Radian Al and Ti mount because I go with light weight parts when I can but it is twice the price.
