"So i bought myself this gun and happen to have one of the earlier generations of M27's from around 2015 and wanna point out alot of the internal differences between both, since the earlier M27s were $450 and not $470 like the current ones.
The QCS Avalon gearbox is a very solid, with a very nice mosfet to boot.
The gun shot 400-415fps out of the box, my previous generation M27 shot around 350fps out of the box.
The writing on the right side of the reciever is smaller compared to the earlier generation, not that I really cared about the size of it, that's extreme nitpickiness.
The flash hider is metal and is not superglued to oblivion, it has a small grub screw that's easy to unscrew, and i was able to unthread it pretty easy with an AR barrel wrench.
The previous generation M27 had around a 350-360mm inner barrel, this newer generation has a 406mm inner barrel thankfully, but still has around 50mm or so of empty barrel space, so I got myself a ZCI 455 inner barrel and extends out to around midway through the flash hider.
The compression parts have unfortunately been downgraded compared to previous generations, the ported cylinder and cylinder head are on par with something ud see in a sportline elite force gun, the crappy tin foil cylinder and plastic cylinder head should be replaced ASAP.
The hop up unit is the black rotary style unit.
The gears are actually not the usual vfc self-shimming gearset, they use normal shafts and I'm assuming are still 16:1 ratio.
The gears sit on bearings, which I'm assuming are 8 or 9mm.
The tappet plate is also the same brittle vfc tappet plate which should be replaced immediately.
The nozzle does have an o ring tho so keep that around.
The piston and aluminum piston head are worth keeping too, those havent changed from previous generations.
The biggest surprise to me was the motor, it's very torquey, not the usual black crappy vfc motor, Looks alot like a ZCI hi torque motor but it uses an o-type pinion gear, definitely worth keeping.
Overall I'm real happy with the gun and definitely worth the slight $20 increase compared to previous generations.
"this gun is great, very durable, reliable, and has that almost real gun feel.
very little stock wiggle
shoots ~250ft (with adjusted hop up) (hop up easy to use)
but pad feels great
easy to get to battery compartment
MOSFET is nice
out of box shoots great
very picky with mags because of the straight mag well
very little battery room in stock (still was able to fit 11.1v stick LiPo)
"I purchased this gun from a different retailer, but Evikeís packaging and shipping, from other items in my experience, is good. Nothing spectacular, but nothing bad either.
Now, onto the gun itself.
This gun is standard VFC quality - If youíve ever owned a VFC gun, this shouldnít be too far off from it performance-wise and cosmetically.
With a 7.4v 20c Valken lipo, it shot around 14-15 RPS out of the box. This isnít fantastic, but itís alright in my opinion. The trigger response, however, was pretty bad. The stock VFC motor is a ferrite 19 TPA motor last time I checked, and it sucked. I swapped this motor for an SHS high torque, and the trigger response is around the same as it on an 11.1v lipo with the stock motor, without the bump in RPS. The stock hop up is actually impressive, and the air seal on this gun is phenomenal. I can hit 8 inch targets from around 65 yards away, which is pretty good for a stock hop up. (Also, elite force claims that the 2015 version has a stock mosfet - whether or not it does, I will have to find out. You can check if you have the 2015 version by looking at the last two numbers of the serial number. If the last two numbers are 15, than itís a 2015 model.) What saves this gun is the fact that it is Tokyo Marui compatible, meaning 99% of aftermarket parts work in this gun. I would rate the gunís internals a 3.5/5.
This is where the ďVFC qualityĒ comes into play. This gunís externals are beautiful. Full metal everything, besides the stock and pistol grip, which are a sturdy polymer. Itís pretty hefty, so be wary to smaller players. Despite this, the weightís very balanced, and itís easy to hold steady for a decent period of time. The charging handle sounds amazing, and the functional bolt catch is a nice touch. Itís pistol grip is comfortable, but it has a little bit of room for the motor to move around, which isnít the best, but nothing terribleís happened, just donít expect perfect motor height. The rails are a little sharp, but a ladder rail cover is an easy, ergonomic, and cool fix. The trademarks are cool, but the paragraph on the magwell kinda sucks a little. Takes away from the gun JUST a little. I would rate the gunís externals a 5/5.
Externally, this is an all-around amazing gun, with an amazing construction and build quality. Internally, however, it performs less-than-stellar for its price.
If youíre a new player and looking for a first airsoft gun, donít even bother with the rest of the reviews. Anything VFC isnít exactly ďbeginner materialĒ. Really expensive. Just please no.
If youíre an experienced player or an airsoft tech, and would like to get a high end gun or a new project that can be modified later, go for it. Itís externals make up for itís internals, which youíre bound to replace anyway. Iím going to be replacing a decent portion of the internals, so for my purposes, it gets 5 stars.
Solid accuracy and air seal
Bad trigger response (relatively easy fix)
Decent gear train (VFC self shimming isnít good, the gears are fine if shimmed normally)
Fire rate (should be a LITTLE faster for a $450 gun)
Spring (mineís at a solid 350 FPS with .2s after less than 15,000 rounds)
P.S. I know the list is longer for cons, but IMO the pros outweigh the cons.
Also, if you replace the motor with a SHS High Torque, and run a high C-rating 11.1v battery, you MAY run into overspin. This can be fixed a couple of ways, but the two I prefer are using either a higher FPS spring or LOWER ratio gears (13:1s). This should do the trick.
