just a side note, my SCAR gen 2 is 3 games old, all stock.
Yesterday, the clear rigid piston had its 1st tooth purely snapped off. And today...
a standart v2 tappet plate works perfectly. I also toss the "auto-shimming" spring on top of the related gears. Sounds useless IMHO if you know how to shim right
I'm very happy with it, it's my 3rd one lol. Wanted to try something else but went back to VFC scar.
lonex M100sp spring, lonex 8mm bearing bushings, teflon tape mod (cylinder head), silent piston head set, piston head o-ring enlargment mod, madbul 363mm python v2 TB, madbul shark red hop-up bucking. paired with 7.4v lipo/9.6v mini. No need to velcro tape the magwell, crappy chinese metal mags/green label pmags feeds perfectly
