  • Ruger MKIV Frame Lug by Volquartsen
  • Worn loose frame lug by Ruger


Ruger MKIV Frame Lug

This lug is precision machined for improved fit. Slight variances to the factory lug (as shown with the yellow circle in the additional image) can cause unnecessary wear to the Mark IV upper as well as aftermarket uppers like the Volquartsen Mamba LLV. If you've noticed that your MKIV frame-to-upper fit isn't as tight as it once was, this new Precision Frame Lug is the perfect fix.

Compatible with the MK IV and MK IV 22/45.

  • Heat treated 416 stainless steel
  • Black Nitride Finish
  • Compatible with MK IV and MK IV 22/45
  • Made in the USA
