The 3 lug interface assembly is an integral 3 lug assembly which adds minimal length to the suppressor. This kit allows for QD mounting of many Griffin suppressors. To view applicable calibers and ratings see individual suppressor product pages. Our 3 lug adapter requires minimal deflection of the spring bushing for installation in some cases negating the need to modify hand stops and grips that come close to the 3 lug adapter. The 9mm kit fits H&K standard 9mm 3 lug adapters as well as Griffin 3 Lug Adapters. US made Barrels from RCM and Michael's Machines comply with these dimensions as well as German HK brand barrels.

Note: The 10mm/40S&W kit is NOT compatible with Griffin 5.56 through 9mm 3 lug barrel adapters which are a smaller diameter. Additionally the 10mm/40S&W kit currently supports the 10mm or 40S&W H&K MP5 only and should only be used on the Bushwhacker, Revolution 45, or RESISTANCE 45 silencer as there is not enough bore clearance to shoot larger than 9mm bullets through 9mm silencers. The 9mm 3 lug assembly can be interfaced with the Optimus, Bushwhacker, Revolution 45, or Resistance 45 suppressors and fired on 9mm 3 lug host firearms.

Made of 17-4 Stainless steel and with a 17-7 wire spring, this coupler kit is heavy duty for full auto applications.

Applicable to the following Griffin suppressors:

Bushwhacker 46


  • 17-4 and 17-7 construction
  • minimal length added to silencer
  • Compatible with standard 3 lug adapters
  • Lifetime Warranty

    I put the 3 lug muzzle devices on my 9mm carbines and my 300 SBR. This makes life so much easier when switching between guns.
