Good Part

by -

Fit and finish on this castle nut is excellent. Uniform Parkerizing, fit both a 3-point stock wrench and a mil-spec buffer tube from another manufacturer perfectly. Works as it should. Couldn't be happier!

Heavy duty castle nut

by -

This is a very nice heavy duty castle nut with great finish. Fast delivery as usual too!

great part

by -

excellent part. much better than the end plate they offer

Doesn't fit

by -

Didn't fitton the buffer tube. Started to thread on but started to strip the threads. Tried a different castle nut and it worked just fine. It did fit my wrench though.

From PA: We're very sorry to hear that you had this issue. We'd be happy to replace this for you.

Pure garbage

by -

Threads were jacked up. Do not buy.

Does what it should

by -

cheap. works well..

Lock solid

by -

Threaded onto the buffer tube like butter. Flawless finish, for pennies on the dollar it's worth its weight in LEAD!

Great Value

by -

Fits snug, with a good finish that matches most uppers. Expo is a great value, highly recommend picking it up on sale.

GTG

Works well, fit/finish far better than I expected for the price.

No good, mine came with no notches for staking.

by -

Mine came with no notches for staking, making it useless for me. The overall the fit and finish was rough and poor quality. I was similarly disappointed with the Expo Arms buffer tube. Spend the extra few bucks for a reputable brand.
