Great product from worker, only concern is that the constant friction of metal and plastic may damage the blaster over time.
Somethings to note that aren’t mentioned in the description or these other reviews. This kit comes with hardware not pictured. Such as the insert nuts for the bolt sled, and a couple other different lengths of screws (if you need clearance for other shells or covers. Comes with an Allen wrench but not a screw driver. I used this pump on a nerf Retaliator with the original barrel. I also have the Orange Mod Works Core Kit, the insert nuts did not need to pressed into the bolt sled, literally just dropped in. Everything is top notch, only concern I have is the Phillips head screws are a little soft. Please use a #2 head or you will be kicking yourself. You will have to supply your own grip but any of the work ones will do. 5/5
Worker Aluminum Alloy Pump Kit for Retaliator
Pros: Easy to install, very durable, fair price, enough picatinny rail to mount a decent sized foregrip, comes with allen key and spare screws.
Cons: No instructions, can't be comfortably used without foregrip.
