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: Russian & Bulgarian Krinkov series rifles/pistols (These will not fit the Yugo M85/92 pistols (*pick Yugo Length) or Romanian Draco pistols(*pick AKM Length).
*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
