For: Systema MK5 Expert Full Tune KitProduct Information:
you may be thinking that you will get the same quality in other upgrade kits for a lower price. think again! this is simply ana amazing upgrade kit. recently installed it in my ics mp5. the helical gears, along with the bearing 6mm bushings, were extremely easy to shim. by far the easiest shim job i have ever performed with any gear set. and on top of that, the gears are quiet and smooth giving you a good rate of fire with the m120 spring included. right now, im getting about 380fps out of it consistantly. but my hop up chamber needs to be replaced seeing that the plastic brace that holds the barrel in place is being held in by super glue and not the included screws. apart from my gun's own flaws, the cylinder assembly is getting a perfect air seal. combined with my madbull 6.03 barrel, the accuracy is amazing, and can easily out shoot any stock gun. now i feel sorry for all the new players ill be shooting at this weekend at Evergreen airsoft in sultan, WA. all of the other included parts (anti-reversal latch, cut off lever, selector plate, spring guide) all work very well and do exactly what they are supposed to do without modification. finally, i have heard people talking about how systema pistons have a short life, but so far that is not the case here. i have put more than 5000 rounds through it so far. the piston shows ZERO sign of wear. keep in mind this was installed in a CA reinforced ver.2 gearbox. overall, this ftk is worth every penny, especially if you have the tech skills and experience to install it yourself.
-superb quality parts
-everything does what it supposed to flawlessly
-a breeze to install (a guarder or deep fire kit would take me twice as long just because the parts arent the same quality)
-none whatsoever (except for the fact that it is only $150 at airsplat.com, which is where i got mine from)
if you are looking for a full upgrade kit but dont want to spend money on many individual parts that may not work perfectly together, then dont think twice about buying this kit. if you want to see this kit first hand, then check out my series "inside the mechbox" on youtube.com, sponsored by airsplat.com. thanks a bunch everyone. be safe airsofting.
