Following the same superb quality as the real rifles this was modeled off of, the PTS Mega Arms Licensed MKM featuring the LM4 gas system is an outstanding training rifle with fit and finish that mere words cannot fully describe.

Featuring a clean and custom look, this rifle not only stands out aesthetically, but also has the performance to back up its sleek look. The Keymod accessory rail runs down the length of the barrel, allowing Picatinny Keymod sections to be added as necessary to cut down on weight. The lower receiver features an enlarged trigger guard machined into the receiver itself for added strength.

The proven efficiency and reliability of the LM4 gas system is at the heart of this rifle. Both high power and gas efficient, the LM4 gas system offers one of the most realistic gas blowback actions in the airsoft industry.

"I own both this gun and the regular lm4, and internals are basically identical. However, the externals are a MAJOR upgrade, the longer barrel is more accurate, a long keymod ris for a ton of attachments, upper and lower feel more ergonomic, top rail can fit a car, crane stock makes it easier to aim. On this one, for some reasom, the bolt catch was actually reliable. BUT DO NOT TRUST IT WHILE ADJUSTING YOUR HOP UP!!!!!!!!!!!!! it can lead to a total of 250$ dollars in damage, it happened to one of my buddies.

nice weight
no wobble
upgrade from normal lm4( IMO )
realistic to real ar15
long upper rail
nice keymod rail
lots of space for attachments
crane stock is comfortable
nice clicks and sounds when using the gun
comes with detachable irons
hop up is very strong(can be con)
real trigger grouping
function while sideway and/or cold

price of mags
gas guzzler
crane stock is impossible to aim with mask on.
price tag in comparison to normal lm4

over all a great buy and is definitely worth it.

"This gun is amazing!! i reallllly love the kick and the seamless rails and upper receiver. Its really appealing to look at.
i was shooting 150 feet consistently every 15 shots i had one stray bb and had no problem with the hop up. one problem is the barrel nut is proprietary.
overall opinion gun is really nice and i really love the kick
trust me once you shoot this gun and use it in a game you wont go back to aegs
