EFFECTIVE IMMEDIATELY: Due to the instability in the price of tungsten, any firearm using an H2 (14.5" barrel) or H3 buffer (10.5" barrel) will have an additional surcharge of $45.00 per firearm. This surcharge is intended to be temporary. Our commitment is to remove or reduce this surcharge as market conditions stabilize and material costs return to more normalize levels. We will continue to monitor the situation closely and adjust accordingly. Prices have been adjusted accordingly on individual buffers and are subject to change without notice at any time. We apologize for any inconvenience this may cause.
