  • When used with a genuine HK recoil buffer, spring and Waffen Burk adjustable gas block, we have found the N+ position is the correct setting for unsuppressed use and the N position is correct for suppressed use, with these settings operation is smooth and felt recoil is light.
  • When we were building our test uppers two out of three of the Waffen Burk gas blocks that we installed on our test barrels required some filing on the sides of the alignment tab on the gas blocks as they were just a bit too wide for the notch on the barrel. Genuine HK gas blocks slide right on and do not require any hand fitting / filing.
🇺🇸 Made in USA.
