Silicone keeps its flexibility when the temperature drops, so the lip still seals on a frosty morning rather than going hard and leaking.\n\u003c\/div\u003e\u003cp\u003eRubber buckings have one predictable weakness: they stiffen in the cold. A lip that has gone hard does not conform to the BB, so the seal breaks down and velocity wanders at exactly the time of year when nobody wants to be re-chronographing between games.\u003c\/p\u003e\u003cp\u003eSilicone solves that by holding roughly the same hardness across a much wider temperature range. The trade-off is that silicone is slicker and a little less grippy than rubber at summer temperatures, which is why Maple Leaf sell both rather than replacing one with the other.\u003c\/p\u003e\u003cp\u003eThe fitment is unchanged from the rubber version. It is cut for Marui and KJ gas pistols and VSR-10 pattern cocking rifles, and the manufacturer also lists it as compatible with older-style WE-Tech gas blowback pistols and rifles.\u003c\/p\u003e\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSilicone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eIntended use\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCold and winter conditions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePlatform\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMarui and KJ GBB pistols, VSR-10 pattern cocking rifles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAlso listed for\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eOlder-style WE-Tech gas blowback pistols and rifles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eAir seal\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eC-clip reinforced lip, as the rubber version\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHardness 50 degree\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eUp to 360 FPS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHardness 60 degree\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e295-390 FPS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHardness 70 degree\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e360-460 FPS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eHardness 80 degree\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e490 FPS and above\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eGood to know before you buy\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eSilicone earns its keep below roughly ten degrees.\u003c\/strong\u003e Above that a rubber bucking grips slightly better; below it, rubber hardens and silicone does not.

Silicone holds its flexibility in the cold, which makes it the sensible choice for autumn and winter play. Rubber has slightly more grip on the BB in warm weather.

A different compound seals differently, so treat it as a new setup: fit the bucking, chronograph, then adjust the tensioner and chronograph again until you are where you want to be.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich hardness should I pick in silicone?\u003c\/strong\u003e\u003cbr\u003eThe same one you would pick in rubber. Go by your muzzle velocity against the figures in the spec table rather than by the compound — the hardness numbers mean the same thing in silicone as they do in rubber, and all four are made.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill it fit a WE gas blowback?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer lists it for older-style WE-Tech gas pistols and rifles alongside the Marui and KJ platforms.
