🔩 Precision-Crafted UNEF Right Round Machine Thread for Ultimate Efficiency Review

Didn't have a 1/2x28. Won't thread onto 1/2x28 Threaded Alignment Tool Covers the threads on the alignment tool, but even with pliers holding the alignment tool (bad for that) it still won't thread onto it. Sent it back, went to cnc warrior and got it.

This is NOT a 1/2"-28 TPI thread as advertised. Do not use this product to thread your rifle barrel unless you intend to use a 1/2"-20 TPI Nut from a hardware store to install on the end of your muzzle and/or permanently ruin the barrel. Very upset about the false advertising here.

Cuts fine threads. This is probably why others had trouble posting this in the guide. Compared to other threads they didn't have the tolerance I expected. The final fit was loose and difficult to screw in. Not happy but I think you get what you pay for. Of course it works, but you sacrifice quality.
