Just a quick bit on these new easy CP rounds, i bought a pack for the marushin m84 and just got round to trying them. Well i say try as i have only tried 1 round so far (time constraints and suitable place to try them as new carpet down and no why am i using caps over it, wife would kill me). So after the excuse of only 1 round fired what's my impression, first thing the det pin, longer than the old one but then it travels further in the round as the det pin actually hits the cap rather than a separate plug as with normal cp rounds. next god it was a tight fit and took some persuasion to get fully home (very careful hammer work on the edge of the pin)due to the fact that it was so hard to seat it i had to re-assemble the gun a few times with a loaded round to see if the round would chamber.
So finally done and round loaded (easy process) i chambered and fired the round and success it fired well great sound pretty loud and ejected very well i fired into a box but i have no doubt the round would fly some distance. Ok so only 1 round so a cannot speak on feeding consistency or reliability but the system does work and i hope that i will be able to fire a mag or 2 soon and let you know if it will fire consistently. With rounds for all models getting hard to find its always good to have another choice the only thing i would say on these rounds is not the round itself but the det pin, one it will be a nightmare to get this det pin out for cleaning due to the fact it was so hard to get it in the barrel, i hate it when you really have to use a lot of force to dislodge these things. two the det pin is very specialised in its shape so i dont see anyone being able to make a det pin for other models.

Thanks for your report Clay'  Very Happy Glad to see you managed to get one off before your wifed came back and caught you  lol! 

I notice you tried these in your Marushin M84. These cartridges were designed for MGC models so I'll be keen to know more about their performance in Marushin's M84.
I have a Marushin model and am very disappointed how quiet it is using standard PFC cartridges. It's almost silent actually as almost no sound gets out of the cartridge.
If these EASY-CP rds work fine and give a decent sound I'd try them myself.

If the Det.Pin is so tight it needs tapping in with a hammer it could be worth sanding it down with some emery paper or even lightly skimming it in a lathe for a better fit.

Looking at photos of the TK M84 pin, it looks like the striking end is ball shaped while others I've seen, .45ACP for example, have a straight parallel sided striker. Something like that shouldn't be too difficult to turn on as lathe hopefully. If TKoba can make them then someone with a decent lathe should be able to  Wink

Surprisingly Cerwyn he has made the M84 det pin specifically for the marushin and i also have the m39 that makes no noise and i will also see if these can be used in i. The rounds and det pin are not badly priced so i think its feasible to experiment with a few models

Here's a good video showing the M84 firing EASY-CP rds:-

At long last I got around to buying a pack of these Easy-CP carts and dedicated Det.Pin for MGC MAC11.
Pin slots straight in without any bother into the MAC.
The cartridges are easy to load and even though I only have 8 rds so far, the fire really well. Good sound and some muzzle flash too as an added bonus.
Attaching the Silencer, for the first time I noticed a definite reduction in noise level using these Easy CPs. In the past I've used MGC CP-HW and Open Cartridges but never noticed any Silencer effect.
I've ordered another 32 rds, we'll see how the MAC likes a full magazine Very Happy

I am a little worried about using cp rounds in the M11 as the first M11 i had blew 3 bolts using cp rounds they just seemed to powerful for the gun. if these easy cp are a little gentler on it i might give it a go. That said how long will these easy cp rounds be availlable seeing as they are produced by tanio ?

3 broken MAC 11 bolts when using CP-HW rds Question No That doesn't sound good at all ... although that said HWABS is so brittle and prone to breaking as we've all found at some time or other.

I stopped using CP-HW in my own MAC because the 5mm o/d 0 rings kept snapping. Open cartridges have no 0 rings so made a better option except that mine use 5mm caps. The "primer" is tiny and prone to being thrown out of the cart with the fired cap. So easy to lose the damned things it's best to either fire so the carts eject into a box or in clear spaces with laminate floors.

Two mags of 30 is about the limit I can fire through my MAC before having to remove the Det.Pin for cleaning. So much dirt builds up on the wide pin attempts at firing any more cause the carts to jam solid on the Pin. Perhaps my Open carts are a fraction tight or the pin's a little too wide scratch

I was hoping these Easy CP carts were the perfect answer but you've got me worried now claymore

Your question about how long Tanio Koba will keep making these for is valid enough. He does tend to stop abruptly doesn't he  Question
