Threaded barrel cover
One of the few places that had a threaded barrel cover for European 1/2 X 20. It fits well. And was less money than other places. Would recommend.

Just what I need
The dial on the Rifle Speed has block sticks over the threads for a muzzle device. I needed something to make a spacer. So the muzzle device would not interfere with the gas block adjustment. I cut muzzle device down to 60 thousands of an inch for the spacer.

Ruger mini 30 tactical version
I removed the flash suppressor from my Ruger mini 30 7.62x39 tactical model because I did not need it for hunting and installed the Grovtec muzzle thread protector 5/8x24 .635" L x 740 OD, GTHM247 and it fit perfectly and has same OD as barrel.

It's just a muzzle thread protector.
It protects the muzzle threads when a muzzle device, suppressor, brake, flash hider, is not attached. Not rocket science. Simple and effective.
