Got a hold of a fully mechanical milspec wolverine which has the reaper 2 engine. Ran it yesterday and it performed well with a few issues. There are 2 small leaks one from the pistol line which I'll replace and another from the pilot valve when the trigger is held in, any advice on this please guys. What is the best combination of barrel make, size, bore and bucking for a general m4 build running at UK limits of 1.14j It has a 10" outer barrel fitted and a very small inner, barrel looks about 200mm 😂 but I have the original outer barrel so am planning closer to a 380mm but will take advice. I've found the tiny Allen key bolts nearly impossible to remove without rounding them, any tips for these? I've also a large amount of mtw and kwa magazines that won't feed in it, is this likely to just be a need for replacement springs? Thank for all answers in advance

Thanks, interesting reply. I am going to play around with the variations of the two and see which one I like more

Seemed to be flying straighter and yeah I remember them hitting harder. Its probably in my mind but I wanted to know the science behind it

My gun was shooting at 1.09j with a 105 spring and 6.03 brass barrel. The gun was accurate and straight with minimal power variations. I changed out the barrel for a SS 6.02 zci and obviously the FPS went up to 1.33j. I swapped out the spring to a 90 and the power settled around 1.06j but the BBs don't seem to be as punchy. Is FPS equal? or would a loser bore and stronger spring be better then a tighter bite and weaker spring.

Will do

Nephew just bought this, had a terrible air seal on stock bucking .74j and +/-15/20fps changed it out to a purple prommy and a bit of PTFE and it's gone to 1.07 @ +/- 1fps 😜 But it's pulling right. Anyone with experience please got an idea for the best bucking without having to file down the window (not my gun don't wanna risk breaking anything) Please let me know

Sent back a low power specna m4 2.0, I've kicked up a fuss about it being repaired and requested a replacement but none are available. The gun is for my son he likes to hang back and take longer shots, he wants a dmr but I've talked him out of it as we already have a tac41 but bear that in mind with the choice and opinions please. Options are a similar specna m4 e-09 2.0 (£310) kyrtac trident SPR mk2 (£320) CYMA CM.097A Platinum (£320) Any and all opinions are wel please

Thanks mate, I've looked at the file and can't figure out how it's different from any of the others for sale on sites, It looks as though you still need to use a bolt? Through it. Can you show me anywhere how it actually locks into a gun with the quick change spring bolt?

That's amazing mate, is it for sale somewhere or is that a 3d print? Do you have the stl

Specna arms 2.0 m4 variant (e-09)

Want to fit drop stock but they all seem dependent on the stock bolt but I have quick change spring, anyone know of a solution?
