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.

"Very solid. No pot metal. Shoots around 420 fps with 0.2s for 250mm inner barrel (mk18).

"I’ve only played a few games with it so far so this is an early review. Out of the box the gun came well lubed and greased from factory and everything seemed to be assembled well except for the handguard which came slightly loose. It does still wobble even when tightened ever so slightly but not exactly a big deal just don’t zero your scope on it. The hop up is in an annoying location being on the bottom of the outer barrel inside the handguard. At first my shots would fly at a legit 80 degree curve to the left because of the hop up but it fixed itself after a couple mags honestly no clue what was happening. The only real gripe i have is about the mag since while being a gen 2 mag it still leaks gas when charging it. Hopefully a moondog o ring will fix that but the mag itself doesnt leak gas. Also it isnt too difficult to load the magazine with a basic speed loader using no attachments. Somehow everynow and then id find a bb stuck in the gas router/gasket and im not sure if that happens because of me loading or if the gun itself is doing it. Still fires well with a bb stuck inside btw. Its a good idea for when you’re chronoing if its a lil too hot for your field but full auto become unreliable. The efficiency isnt too bad can almost get 100 shots in 60 degree bay weather. The recoil is also nice and heavy though a little sluggish but not much. Btw ghk g5 mags work just hopefully they dont go out of stock too soon though evike should theoretically be stocking the king arms gen 2 mags soon so keep an eye out

Overall: Good gun especially if you cop it for cheap off someone who got one in the mystery box and doesn’t want it. Thanks once more to the dude who sold it to me for 280$
