Reviews & Ratings for Primary Weapons Systems EBT Mod 2 End Plate and Castle Nut — 123 reviews — Page 1

I love these and put one on every built i make. I've never had any problems. I know school of a American rifle hates these because they're one use only if you take them off again but I never reuse a traditional endplates and castle nuts anyway. Plus I don't typically take them off either so it's a win win in my opinion.

These are my go to parts for an end plate and castle nut on all my builds. Love that I don't need to stake.

Have you ever needed to take your buffer tube off? I have, and while I can appreciate a good staking job, it is not easy to deal with should you need to do anything buffer tube related. PWS solves this problem in a simple yet elegant way. There are detents pins all over an AR, this adds one more but in a useful way. I would especially recommend to anyone who tunes their AR’s, or anyone that uses a chassis that is setup to use a AR-style buffer tube/stock.

This is the easiest one to install, it looks great and its reusable, over and over. This is my second one and I should have got more and I will when I do my next build or mod.

The rachet locking feature is great. I don't stake, and I have never had one come loose. They are quality machined and have a great finish. I have them on all guns that use them.

This set makes it very easy to get the right amount of torque on your receiver extension without having to stake the castle nut after installation. The QD mount on the end plate is a + and the finish is solid and consistent. Will definitely be using on all my future builds.

This is my go to castle nut end plate combo whenever I put together an AR.

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.

This is a great castlenut and end plate that ensures you don't need to stake it. However, it is a one and done item. If you ever take it ofd, don't reuse it!

Originally several years ago, I simply wanted a QD socket end plate..I ended up going with the PWS end plate and never looked back. I’m currently have two and have never had a single one back out. Not having to stake the castle nut is always nice as well. Well worth the investment.
