Patterned after the original ArmaLite AR-15, this venerable weapons platform has gone through numerous updates and evolutions through the years to become the go-to choice for military personnel, law enforcement agencies, and civilian shooting enthusiasts alike.

The Special Operations Peculiar MODification (SOPMOD) Block II is an accessory system for the M4A1 carbine comprised of a full length monolithic rail system and a heavier free-floating "SOCOM" profiled barrel. The real life counterpart of this barrel would provide better accuracy versus the original and helps to mitigate heat when firing with a suppressor or when in cyclic.

The Daniel Defense licensed RIS II handguard is a free-floating, two piece, ultra lightweight front rail system. It provides a full length mounting surface for all 20mm Picatinny compatible accessories: From grips, lights, PEQ boxes and anything in between. The handguard system is designed to accommodate an M203 grenade launcher with no special tools required. Integrated Ambidextrous QD Sling Swivel Mounts Points provide modular, limited rotation to suit your preferences. The ultra lightweight, free float design allows for quicker target acquisition.

"First airsoft gun that I have owned. This gun performs perfectly and looks hot as hell 🔥! One minor problem that I saw was that when I was taking off the upper of the gun, the charging handle spring got caught and it broke. This resulted in the dust cover no longer working. Although over all I would recommend this gun to any softer. I would also recommend getting a 11.1v for this gun.

"I hope my review is useful to someone. I've been playing for 25 years and this is my 29th replica so I have some experience with it. The replica is very well made, the logos are beautiful and it is not heavy or unbalanced as I had read on other reviews, indeed having the barrel and the gas block in aluminum is less unbalanced than a 416 for example. The handle is made of very good plastic material and the low receiver are just 29.5mm wide so the magazines are firmly in place and do not wobble in their seat. This is a detail that few look at, as you know real m4s are about 28mm wide and usually the airsoft aeg replicas of almost all brands have 30-30.5mm lower receiver, these are the narrowest and closest to the real I've seen. I have tried magazines guarder, g & g, g & p, vfc and fishing with all without problems. I did not try the original barrel and rubber / pressers because I immediately replaced them with other aftermarket ones that I had, however, the pattern of the replica is very narrow and very precise. The only note is that I found it not very constant on the chronograph, perhaps due to an air leak so I decided to take it apart. I found all the screws that weren't tightened, the air unit leaking a little air and the gears not very greased, so I greased both the gears and the air unit well, leaving all the original parts. Having done this, I found him very constant in shooting. The second criticism concerns the mosfet in the stock, unfortunately the cap with the screw in the tube tends to scratch / tear the gasket of the mosfet once tightened, to remedy this you will have to file the cap at the bottom by removing a portion in the shape of a half moon, done this the mosfet will no longer be touched once the screw is tightened. Having said that and made these two interventions, I recommend this replica, also because I have not found a single replica that did not need an intervention in my life, it has an excellent value for money.
