Well, pdi 240% aps2 spring (a m143) was giving it a 3.2 joules on 0.2 gram bbs, so it has more fps on weaker springs, 41cc of air doing its work

+Massakre8492nd I see bigger cylinder requires a lesser spring to produce equivalent power so easier to compress 👍 Might need to get this dealio.

+BrainExploder do not forget about joule creep, heavier bbs will be also be propelled faster, apparently my 26 inch barrel has barrel to air volume ratio of 2.2 so now i need to chrono with my bbs of choice, like the hpa guys do

Got my kit today the install is extremely easy and the pull is much easier with the included spring, I have yet to chrono it and see where I stand in the FPS department but good on you Silverback for listening to customers and fixing the biggest thing plaguing this gun, my left arm thanks you.

one more thing a M140 that is with the kit is actualy calibrated to srs air compression, it would be a m120 or even weaker compared to other manufacturers springs

Ehobby asia got it, fubar bundy uk is confirmed to have them in offer, gunfire will have them later

Il serai bien d'avoir les ressorts compatibles avec ce kit car l'indication APS est trop vague, car il y a APS ; APS-2 qu'elle différence quoi

L'APS et l'APS II sont des répliques de fusil de sniper produits par Maruzen, qui étaient très utilisées dans les années 2000. Tous les fusils de sniper Maruzen utilisent le même type de ressort, par conséquent tous les ressorts indiqués compatibles APS/APS II/Type 96 seront compatibles également avec le kit pull back de Silverback.

Nickel c'est bon à savoir merci à vous !
