  1. Back in December I contacted JSI wanting a foregrip that was capable of withstanding the forces needed to prime a LS that had an 8kg spring in it. After shelling out ideas we came up with the pictitinny Longshot foregrip. The grip was exactly what I envisioned it to be on paper. JSI is one of the best nerf moddng groups around and will always contact them if I need something done.

  2. Worth the wait. Just got a big shipment back from JSI in the mail-- a sweet Mav repaint and a Rampage foregrip conversion, among others-- and everything came out awesome. Between that, the good prices, and the can-do attitude of the crew, I'd definitely come back to JSI for whatever I need.

  3. Commissioned a Styfe Masterkey taking the advice of the JSI guys on a suitable spec/config. It arrived in great condition and a very solid build which was one of my main concerns. Performed great in a recent HvZ event and would recommend JSI for all your Nerf modding needs!
