Primary weapons system (pws) ratchet lock end plate - Primary Weapons Systems EBT Mod 2 End Plate and Castle Nut

The Primary Weapons System (PWS) Ratchet Lock End Plate is absolutely the best and easiest way to secure an AR’s Receiver Extension (i.e., buffer tube) to the lower receiver. When the ratcheted Castle Nut is tightened against the End Plate it provides an excellent lock that will not vibrate free under extended use. Many reviews will say that no staking is necessary, and that is unquestionably true. Most manufacturers recommend that a standard Castel Nut should be torqued to 40 ft/lbs. Since many home builders don’t use a torque wrench for this purpose, there is no telling how much torque is being applied to tighten the nut. With the Ratchet Lock End Plate, a builder can use much less force to attain a good snug fit that will hold over extended use. Another plus is that the ratcheted Castle Nut can easily be removed using a standard Castel Nut Wrench for maintenance or Receiver Extension change-out. This can be done numerous times with the reuse of the same Ratchet Lock End Plate parts. The fit and finish on the PWS parts are outstanding and bears a very nice look for a quality build.
