This is a new muzzle for your SLAB v4 made by SillyButts, inspired by the nerf slingfire. This muzzle is designed for the v4, I do not know if it will work with the v3, as I do not have one. This muzzle ONLY WORKS WITH THE SHORT PLUNGER ROD, and replaces the need for the little cap on the original muzzle as well. This design is based off of SillyButts's original slab v4 muzzle, I only made the cosmetic parts. There is not any extra hardware required for this muzzle, in fact it omits the need for 2 screws. There are no special directions of installation, just follow SillyButts's guide on YouTube for installation. If you plan on putting this on your slab, just keep in mind that you wont be able to use most scars or bcars if you don't have a rather long barrel installed.
IF YOU PLAN ON INSTALLING IT JUST REMEMBER: You will not be able to use most scars or bcars without a barrel of at least maybe 18 inches in length. Also, you can only use the short plunger rod which can have issues with higher spring loads. Mine has a k26 and has not had any issues though.
If you have any questions or problems with your part, feel free to comment and I will respond as soon as I see it.
You can find the files for the SLAB on SillyButts's github
