THE ORIGINAL "Swiss Cheese Grater" was designed in 2016 by Khyber Customs and is the only vented gas tube cover that includes a superior Melonite QPQ coating (vs. Black Oxide or Phosphate) which provides improved corrosion resistance, wear resistance, and case hardening.
Compatibility: OPAP/NPAP M70, M85/M92 Pistol, M76/77/90, and many other Yugo Pattern Rifles. Does NOT fit M72 Pattern rifles.
*Removable and compatible with like-pattern gas tubes (not permanently attached)
*18G cold-rolled steel (very solid, but with little effort can be adjusted for fitment)
* BLACK Melonite Coating (for corrosion resistance, lubricity, and also serves as a great base for the final finish of your choice)
* Interior brace weld (reduces vertical movement against tube)
*Made in USA
