Great price and these rails hold their own to hard use. They can be damaged when installing removing with poor tool use and damage a tooth - These are great spares and all dimensional identical

Ordered and delivered quickly fit well

ohhunt® AR-15 Replacement Barrel Nut For Round Type Free Float Quad Rail Handguard

Bad quality thread pitch is different and all around a **** item.

Fit perfect! Actually a better design than my original barrel nut.

This was well worth the purchase since the item I purchased was coming from China.

I bought a kit quite a while ago, and when I finally got around to working on it, I discovered the barrel nut was missing. I emailed the company twice with no response, so I searched until I found this one. It fits perfectly!

Thanks again for the parts you guys did good
