Description:
The Mega Arms LM4 GBBR is a game changer for the airsoft world. The LM4 brings together two characteristics of gas blowback rifles that traditionally remain separate, affordability and reliability. The LM4 has taken many years to engineer and assemble and it's finally ready to come to market. The majority of the gun is constructed of aluminum, such as the receivers, barrel, and buffer tube, while the hand guard, pistol grip, and stock are constructed of a high grade polymer, just like a real rifle would be. The bolt movement is crisp and the recoil is very direct, and feeling that this gun gives you while being fired is unmatched by any other gas blowback M4 on the market. The construction and feel of the gun are second to none.
Another very impressive feature of the LM4, and one of the key components in making the gun operate smoothly as it does is the magazine. The magazine holds the gas to operate the gun and the 40 rounds of ammunition. The top of the LM4 PTR Magazine is made of high impact polymer whereas the rest of the magazine is made of metal. PTS has done this for two reasons; first, the top of the magazine will be much more resistant to breaking if dropped, and second, the magazine top and feeding lip can be replaced and the magazine can be rebuilt should it become necessary. The LM4 is an amazing rifle that has been engineered from the ground up to be the first and last gas blowback M4 that you will ever need to buy.

Product Information:
The MKM LM4 is by far one of the best rifles I have owned. The look, and the performance all makes it worth the low price that is listed. Fantastic performance, and deserves a certain 5/5 star rating.
Pros:
This Airsoft Rifle is completely metal, providing it with an extremely real, and fun feel.
This rifle has such a great price for what it is worth, considering it is a gas blowback rifle.
Cons:
The round capacity is held at 40, making reloading more well known.
The rifle has a loud, realistic sound to it (Due to the blowback) that may give away your position, or just disturb your neighbors.

Product Information:
Didn't buy this on here, I bought it at a local shop. As a owner of the first LM4 system and LM4C, the MKM's internals are identical and swappable (I had to swap the bolt-catch assembly with my LM4 because it wasn't resetting when I powerstroke the bolt). The action is smooth. The recoil is stronger than the LM4/C (but still has the poly buffer plate). The trigger squeeze is nice. The keymod rail is mil-spec'd, so all real-steel keymod accessories work (like BCM accessories, for example). Other things: LM4 mags are compatible and (supposedly) if you ever wanted/needed to, you can use the upper on the LM4 lowers. Current setup: Provided irons, MFT Battlelink BUS mil, PTS Battlecomp 1.5 Flashhider. PTS Rainier Arms Charging Handle.
Pros:
Overall well built.
On the slightly lighter side (7.1lbs without mag)
Dat powerstroke action (without having to mod the bolt-catch, too!)
Swappable LM4 parts/mags
Top rail
Harder recoil (than LM4)
Flatter skeleton trigger
Very accurate
Cons:
Bolt-catch piece slightly warped so it wouldn't reset (and thus, powerstroke); rubbing on the lower (was replaced with LM4 bolt catch
The safety switch can be easily (pt. 304) pushed out.
Typical KWA crane stock is used and feels flimsy (highly recommend replacing)

Product Information:
Well I got mine and I agree with everyone else, NICE piece for the dollar spent. Full metal, nice trades, great blowback! Mags works great, fit well hold a decent gas charge, although only hold appox 40 bbs. Great to use a as a trainer. The charging handle feels great, trigger take up is good, over all feels really good nice quality. I would buy another LM4...
Pros:
Very customizable, I put a MIAD grip and Vltor stock on mine no issues everything fit just fine...also changed out the sights to Troy flip up style, recently added Noveske keymod covers...looks very Chris Costa / Ludas style...good for a PMC loadout
Cons:
Butt stock feels cheap compared to rest of rifle, sight are kind of cheap side also, Keymod accessories are not easy to find right now, but I'm sure this will charge. Finish is wearing off by dust cover from it hitting lower when it opens...also not a Milsim kind of rifle...kind of heavy for Milsim type of events, mags are pricey...

Does this meet Canadian rules for export.
Can it be upgraded to meet the rules.

Staff Answer:
Due to the unpredictable nature of gas blow back airsoft guns, in regards to muzzle velocity, we are not currently offering them for our Canadian customers. We cannot guarantee their compliance if inspected at the border. 3921 days ago 0

Are there any different upper receivers that will fit on this gun?
I was just curious if you sell upper receivers that fit, or if you sell the same type of upper receiver that comes with the gun.
