I am from india i have same 12 sub, but in india we have limit of 15 foot pound is there any way to increase power in impact m3 mine in .177 600mm barrel. I have fire arm license but in india avaibility of .22 airguns is a big task and peoples ask half ammount of fx impact for .22 barrel so i dicided to keep only in .177 and because of license i dont have any power limitations on airguns so please help me to convert it into fac version
Just a quick question regarding pressure consistency.. when i fill my impact sub12 at say 230 bar is records 11.8 to start with then as the pressure diminishes in the bottle it records 11.0 at 100bar is that normal? As i would like to have the same pressure right down to 100 bar.. my reg is set at 55bar and its a huma reg. any advice? thank you
Hi yes we did the 720 👍and with a plug in to take up some of the volume it was great and stayed on the gun👍 we did away with the return spring in the plenum tube we put a different one in the valve adjuster and it worked a treat, you could wind the adjuster knob in and out all the way and still be under 12 lbft i locked it anyway but the m3 in the end had the 720 valve adjuster micro adjuster all locked off except the power wheel and the gun was spot on👍👍
I have done that in the past but I found they tended to spike when coming off reg, which I wasn't comfortable with, although now we are running a longer heavier valve return spring and we are getting some nice results still using the lower reg pressures. But that being said other people have tuned like that and got very good results, I think it all depends on the barrel and your individual rifle. Thanks for watching.
Possibly yes, you would obviously have to play with the settings a little, but you should be able to get similar results, and if you don't its a pretty easy job to just swap the tubes back around. Thanks for watching.
Airbuks has a vid on fitting a power plenum kit to a older impact, but its pretty much the same for the M3, have a look on his channel. Thanks for watching.
Wet or dry sand paper on a nice flat surface, I start off at 2000 then work through to 9000, takes a bit of time but worth it in the end. Thanks for watching.
Yeah the FAC rifles do hog all the air, just a little annoying when I was getting over 500 with the smaller plenum, since this vid we have plugged the plenum up and now we are getting the 600+ shot count again. Thanks for watching.
Shame about the efficiency but it’s great it’s more consistent. Actually, 300 shots/fill isn’t so bad is it. Have you looked into the RTI Prophet performance model? If you have fac. Would be interesting to see you work your magic with that.
300 shots isn't bad, but I was getting just under double that with the small plenum, and it did not really make the rifle any more accurate, its just made it a little more consistent, next experiment is a very small plenum and a high reg pressure. Had a look at the RTI stuff a few years ago, nice bits of kit but they look a little minimalist for me, but you never know if one comes up I might take a look. Thanks for watching.
@@sub12airgunners Yes be interesting to see what small plenum and high reg does, will look forward to your findings. Be good to see also what the highest efficiency shot count was and what was needed to achieve that. I am just getting a variation on my FAC to add an airgun and I’m torn what to get. Fx Maverick, impact 2, M3 or the RTI Prophet performance. It will be great if you could get your hands on a profit performance and put it through its paces. I think they are a bit agricultural but would be good to see what you could do with it to refine it. They are also a tad cheaper too! : )
Did you used to have a video showing fitting the plenum or did I imagine it?

Great videos!!! Did you figure out how to put a return spring into the power plenum?
How did the 720 go if you done it that is?

Awesome info thanks 😊
Glad it was helpful! Thanks for watching.
Any reason why u don’t run the reg higher and really close the front valve? So u get a short fast burst
I have done that in the past but I found they tended to spike when coming off reg, which I wasn't comfortable with, although now we are running a longer heavier valve return spring and we are getting some nice results still using the lower reg pressures.

@@sub12airgunners Are 12 fpe barrels not working well with higher speeds?
Interesting results do you think the results would be similar if the sub 12ftlb maverick tubes were swapped around?
Possibly yes, you would obviously have to play with the settings a little, but you should be able to get similar results, and if you don't its a pretty easy job to just swap the tubes back around. Thanks for watching.
@@sub12airgunners thank you that's just what I was thinking👍
Could you make a plug for the 720 power plenum
Yep thats what I am going to try next, I have ordered the 720 plenum so when it arrives ill have a play around with it. Thanks for watching.
How you install power plenum kit on a M3 ?
Airbuks has a vid on fitting a power plenum kit to a older impact, but its pretty much the same for the M3, have a look on his channel. Thanks for watching.
Another great video. Do you do work on peoples rifles?
Sorry no, we don't hold a RFD licence so we can't take in other peoples rifles. Thanks for the interest though. Thanks for watching.
@@sub12airgunners that’s a shame! Would love to do some of the mods which you do on your FX’s!
Hi, what do you use to polish the reg
Wet or dry sand paper on a nice flat surface, I start off at 2000 then work through to 9000, takes a bit of time but worth it in the end. Thanks for watching.
@@sub12airgunners thanks for that 👍
Hiow many bar to set regulator 1 and regulator 2
I run 130 bar on #1 and 80 bar on #2. Thanks for watching.
Fascinating ...
Glad you liked it. Thanks for watching.
I wouldn't complain about 300 shot count - my FAC impact Mk2 will do about 30 shots
