Patriot's Review of Guntec USA AR-15 Castle Nut For Car/M4 Buffer Tube
Bought this to use with the SBA3 pistol brace that I installed on my AR pistol build. Quality manufacturing of the castle nut made it a breeze to install. There are no sharp edges. Precision cut threads help to prevent galling. Plan on purchasing another one for my next build.
Pros:
- Minimal size weight rigidity
Cons:
- None
Would Recommend:
Yes
