Adjustable gas block for HK rifles for HK MR308

For MR223 available from stock with us. Please pay attention to the respective delivery time indication.

Since Heckler & Koch does not deliver an adjustable gas system for the civilian market, we rely on the adjustable 5-position gas system developed by Waffen Burk, Heilbronn, for the HK rifles. First-class manufacturing from master hands combined with the best components, proven and praised many times, distinguishes the "Burk gas system" for the MR308 and MR223 from Heckler & Koch for years. We are pleased to offer this premium product to our HK-MR rifle owners and would like to thank Waffen Burk for the always friendly and uncomplicated cooperation.

Waffen Burk's passion is self-loading firearms, especially their in-house development, the model BR10! For this, Burk manufactures almost all individual parts himself or has them produced by service providers in the region. His focus is particularly on the quality and high reliability of the products!
