Orange Mod Works Stage 1 & Stage 2, shotgun foregrip, single point sling. This beast takes so much pressure to prime that the stock kept collapsing against our shoulders. We remedied this by permanently attaching it in a fixed position with four screws.
I've always wanted one of these professional shotgun foregrip kits. For years I have been eye-balling the awesome one over at XplorerSG in Singapore but at 90+ USD, just couldn't justify the cost. They sell the grip as a kit, but if you also want the priming handles they sell those separately.
I picked up this particular 3D printed shotgun foregrip from seller yifan9 on Ebay for 45 bucks plus 9 dollars shipping. This includes the priming handles as well. This is the same seller that does the 28 dollar 7 dart Hammershot cylinder. I
am really impressed with the quality. The price may seem a bit high, but it's one of those items I've always wanted and you can never be sure how long some of these custom NERF parts will be available. Also - it's around half the
cost of the one they have for sale over at XplorerSG.
