Perilynx Pump (Experimental)

So the s400 uses some of the space between the foregrip and trigger as additional spring space. That could mean more potential draw when translated to a Lynx. Only problem is that it completely breaks the trigger linkage, and I'm not keen on changing the receiver for a pump mod. The shoddy solution here is to take 1mm string and rig it to a pusher for the catch. It feels bad, but it'll do until I find a better solution (the s400 has the benefit of a much narrower spring and wider pt freeing up more real estate for the trigger linkage). Just switch out the pump, shroud, and plunger to gain 80mm of draw and the ability to fit full length k25 with some room for spacers. Downside is the aforementioned awful string trigger as well as the pump now being poorly constrained. The latter can be addressed with a bearing prime, but the former requires finding a viable trigger linkage.

Hardware: full length k25, 2 m3x20mm screws to attach the shroud extension, 1mm string if you don't want to push the catch with your finger, and longer 8-32 threaded rod if you can't fit the tail on yours (can be skipped entirely if you don't see plunger sag).

I hit around 300 with sf25 and a 55cm worker barrel. there's likely more gains to be had with a longer barrel, better airflow behind the plunger (added after the pic), and a longer barrel.
