The KWA Maple Leaf KSC/KWA EVO 3 Hop Up Tensioner EZ Packing 70° is a straightforward internal upgrade for KSC and KWA rifle series gas blowback platforms, excluding the MP7. Built around a stainless steel hop-up lever with an integrated design, it is made to deliver a better seal than standard parts while keeping the hop unit layout neat and functional.
A fixed O-ring helps make assembly easier, which is especially useful when you want a cleaner install without fighting small loose parts. In use, that improved seal can help the hop system apply pressure more consistently, giving you a more predictable shot path and steadier performance during skirmish play.
This version also includes the Maple Leaf SUPER GBB hop-up bucking in 70 degree hardness, making it a useful option when refreshing a worn hop unit or building a more refined KWA or KSC rifle setup. It is also suitable for KWA and KSC PTS Mega M4 platforms where compatibility matches the rifle series fitment.
For compatible hop-up parts, GBB rubbers and other airsoft internal upgrades, add this to your build today.
