Excellent quality
Perfect fit on multiple heavy barrel rifles I've used them on. Better quality than the ones off of Amazon for the same price.
Works just fine
Doesn’t quite line up with my heavy MTU barrel profile at 26”but that’s no big deal for me. The length was perfect to cover the threads but not overhang the crown.
Great value excellent quality
5/8-24 real nice well machined.
Good thread protector.
Threads cut perfect and nice knurling. Good product.
Quality
High Quality and Perfect fit.
Good quality but bad performance
This thread protector sticks out slightly past the end of the barrel causing interference with the gas coming out of the barrel and forcing cone. This caused the groups to increase by double out of my Grendel. With out any break or thread protector it constantly shoots a 1 in group with Hornady black 123gr eld m and with this thread protector the groups where 2-2 1/4 inch groups. This was a well made product with clean machining but my rifle didn't like it at all.
