New US made 1/2 X 28 thread protector designed for HK MP5, MP5K 3-lug & threaded barrel applications.
This is the ideal thread protector for use on MP5, MP5-N & MP5K-N style 3-lug and threaded barrel types. This is the factory correct thread protector to support all RCM MP5, MP5K & USA made barrels.
Each thread protector measures:
-Overall length: .50"
-Overall diameter: .590"
-Inside thread type: 1/2 X 28 right hand thread.
Each is made from ordnance grade steel, turned on Swiss machines with the finest ultra hard finish available.
Please note: The POF barrels are not factory spec and the use of this thread protector on a POF will not work properly. They will also not cover the threads completely on SP5/SP5K barrels.

I have bought several of these thread protectors through the years for many different guns. Always a perfect fit and great looks with the concise knurling.

This is a great thread protector, the outside diameter is the same as the barrel so it does not add extra bulk. I did however find out that my threads were not 1/2 x 28 as the specifications said on my rifle (it is actually 1/2 x 32 which i ordered and it fit great), but I put this on a 9mm pistol and it is much more streamlined than the one that came with the barrel.
