Ascend Armory Mod2 QD End Plate/Castle Nut Kit
The Ascend Armory Mod2 kit pairs a 7075 aluminum end plate with a QD socket angled 20 degrees, which leaves more room to press the QD button and pull the swivel than a straight socket. The included aluminum castle nut locks with a set screw, so it does not need to be staked to stay put.
The plate is anodized and weighs 0.46 ounces, 0.2 inches thick at the top and 0.45 inches at the bottom where the QD socket sits. Next Level lists it for both AR-15 and AR-10 rifles.
