GDW1316's Review of Primary Weapons Systems EBT Mod 2 End Plate and Castle Nut

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.
Pros:
  • Design
  • Detent works
Cons:
  • price
Best Used for:
  • Anyone who tunes.
Would Recommend: Yes
