Hey guys new here. I have a type 89 not the m4 but I'm pretty sure they're the same internals. Very little info or help with mods on the 89. Great advice so far and gonna invest in the nub and and modify bucking but not a barrel as it was shooting 345- 348 fps last weekend on nuprol green. For those of you struggling with loading your mags I've found a loader which arrived today.
I was sceptical at first but wow they go in like butter. Only loaded 3 mags so not sure on how long it'll last but will use it on a skirmish day and see how it holds up.
It's called a hurricane storm loader by warmag and I got it off a place in Italy.
So if I understand with changing the nub and bucking at 345 fps on 0.2, I should be able to hop 0.36's and get like 70m range?
Hang on this drum mag you're saying won't fit the mws?
