The weight and speed of the cycling mass is quite a lot to put on top of a 6mm BB and a rubber sleeve (the hop-up bucking).\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"text-decoration: underline;\"\u003eHow we solved it\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003eThe Crimson bucking fixes this by having a thick and durable initial opening. It takes considerable pressure for the BB to be pressed into the hop-up rubber, which helps prevent the bolt and nozzle pushing the BB too far past the contact points. \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"text-decoration: underline;\"\u003eThe Benefits\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003eThis allows for a far more consistent flight path which ultimately makes your shooting experience more predictable. No more worrying if your BBs will fly slightly more left, right, up, or down. \u003cbr\u003ePaired with this we also have a contact patch with two points of contact. This shape with the valley in the middle helps align the BB totally in the middle, whilst applying more than enough pressure for even the heaviest of BBs.\u003cbr\u003eWe also use a material called NBR to construct the Crimson bucking. This rubber is far more durable than your traditional silicone rubber, which could easily tear during installation. \u003cbr\u003eThe Crimson Bucking will be sure to last you a good while before any necessary maintenance. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003eWe have tested the Crimson GBB hop-up bucking in a wide range of GBBs.
