Joker STP with a drop forward and a rear velocity adjuster
Improves gas consistency, great forgrip, looks cool
takes an adapter to fit my gun, only comes with asa threads
Very nice adition to my gun. My velocity went from jumps of 10-50 fps to only 5-8fps. Very helpful. Great forgrip help. Takes a mini cocker adapter from ACI to fit my gun. Great price, only 31 after shipping. Easy to install and adjust. Gave it a 9, because there are no threads for my gun, only asa .
