THE ORIGINAL "Hater 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: WASR, RAS47, PSAK47, C39, AMD63, MAK90, Arsenal SAM/SLR (NOT Krink Models), VEPR12, DRACO, SAIGA SGL, and MANY MORE AKM/AK74 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
