    Amazing Bundle

    Posted by Stärke on Feb 24th 2022

    This bundle deal is super super sweet! All were simple and easy to install! Charging handle gives significantly more leverage when charging a round, guide rod replaces the cheap plastic with robust metals, and the sear spring SIGNIFICANTLY lowered the trigger pull by a lot. I don't have a measure but I can instantly feel a huge difference in pull tension. Cannot wait to shoot with the new internals now. Also with installing you get a chance to deep clean and oil your firearm!
