IFX M4 vs. M3?

Is the FX M4 really that much better than the M3?
No, just a better trigger system, slightly bigger plenum, and a copy cat of the top rail system that BRK has. Depending on which model/year M3 you get will define whether you get the newer AMP reg (brass piston) or the older (plastic piston).

If you are like me (FX fan) and you find the trigger on the +$2,000.00 M3 to be an abysmal joke for the money you might be tempted to dip your wallet into the M4 pond.
I chose not to. All that money for a good (?) trigger that should have been on their flag ship gun from introduction in 2017 or whenever it first came out.
I Have spent hours trying to tune my Impact triggers to attain what FX claims is a match grade trigger. A pox on FX for stating that trigger is match grade. I finally just eliminated the first stage and use only the second. My Impacts now have pretty good triggers but I prefer a two stage.
I don’t trust FX’s evaluation of what constitutes a match grade trigger.

I have done this and now am happy with the trigger. Technically I have eliminated the 1st stage as you have said. But at the same time I have incorporated an other way of having the 1st stage which is completely independent of 2nd stage.
 
M4 is better trigger, bigger plenmun, easily slots for trigger and prob adjustments, sliding top rail, and just look way badass. If you getting a new impact, why the heck would you go for an m3? Unless you get a good deal on a m3, I would suggest just get the m4 if price is very close. The only way I would get a m3 over an m4 is if I can find a m3 under $1500. If not, m4 is the way to go.

That's exactly the kind of deal I'm trying to find on an M3 but I'm with you on the fact that if price isn't much different than m4 all the way🤘
 
I think it depends on it you want a single reg or dual reg. Not everyone likes the dual reg FX system, I like them for 177 and 22 Cal setups. The other upgrades are nice to have for sure if you want a single reg pcp. If you are buying new I think the M4 makes sense, if you want an Impact. If you are buying used there have been some great deals here in the classifieds for Power Block M3 Impacts since the announcement of the M4.

I've been air gunning for about 2 years now but I've only had experience with the more entry level guns like hatsan,umarex, AEA and I'm trying to step up my game. What would be the advantages/disadvantages to a single or double-regulated gun?

Single Reg:
Advantages, less orings and points of failure, you can set them higher for the higher power pcps usually.
Disadvantages, can be a little floaty on some designs and fluctuate with bottle press by a small margin affecting fps spreads.

Dual Reg:
Advantage, might give more consistency in final reg settings and fps.
Disadvantages, more orings and points of failure, limit overall final reg setting due to needed pressure differential between regs.

Some will argue the degree these things matter or how much they will affect your performance. Personally, like I mentioned above, I like the duals on low power setups. My 22Cal was a dual reg M3 for a while and I like the long term consistency it provided. My high power 25Cal slugger Impact MK2 is a single reg set at high pressure ~150-155Bar and you cant really do that on a stock M3. Really it depends on what you want out of your setup and what you intend to use it for. My single reg Wildcat 177, and my dual reg Maverick 177 both shoot almost the exact same so it may not matter to you which you pick.

Ahh okay, thanks for the info 🤘😎👍

Regardless of whether you have an M2, M3, or M4, you can tune the rifles to spit out your chosen projectile at the same power level. All you, the shooter have to do is use your marksmanship skills to hit the target. All these changes are subtle and/or inconsequential. I believe the most important change is a stronger backbone, and you can get one for your rifle from Airmarksman. Money will not make you shoot better.
 
i would say either one the m4 does have a little better trigger better regulator piston brass vs plastic the plenum is the same 720 and 750 only thing changed was the letters same volume.
with the release of the new leopard, you may want to wait if you want the M4, i can see the price dropping on the m4 as it did on the m3s not much but enough.
if you notice there also fading out the impact with all these new air tube barrel gun platform.
i have 2 M4s and 1M3 22 25 and 30 best thing i can say is take your time setting the gun up, it pays off.

Older fx prices will come down. There is an m3 with a bunch of expensive saber add ons sitting in the classifieds for 1600. An un shot one for 1500. Bullet central has a brand new .30 for 1600. They also have several upgraded maverick snipers that come with over 100 dollars worth of ammo for 1550. None of it is selling.
