"This gun is well worth the money you pay for it. The recoil is insane for an airsoft gun, and the gun overall feels very high quality and solid. I would highly recommend it for any experienced player looking for a great and reliable gas blowback rifle. The only problem I had was when I used propane, and bolt catch simply would not engage. Definitely use green gas with this gun as I found it works much better.

"I absolutely love this GBBR. I ran it last weekend and I could easily outrange the majority of players. The recoil is solid, the trigger pull is nice amd these mags are amazingly efficient. Even when we stayed for the night games the temperature dropped down to 45 and I was still getting about 300-315 FPS out of it. I don't know about any other GBB that could put out that velocity so consistently. I would reccomend this rifle to the more experienced person that has handled a GBBR. It needs maintence but when it is well maintained there isn't a lot of guns that can outperform it.

Accuracy at distance (150+ feet no problem)
Consitent FPS even in cold weather
Solid Recoil
Durable construction
Great product for the price

Cons if you've never had a GBBR
Heavy mags
Low capacity
Low rate of fire

Don't expect to be able to just hold the trigger down and suppress a hallway for very long AEG users. Ammo goes fast when you only have 40 rds a mag

"Ive had this gun for about 6 months now and i can say that the lm4 is one heck of a gbb rifle. It shoots great, and feels great. This gun is extremely solid, and i have yest to be disappointed with it. Though this gun performs pretty well right out of the box. I would recommend replacing a few parts internally. firstly i would replace the stock buffer lock to a steel buffer lock if your looking to run a heavier buffer in this gun. secondly i would pick up some replacement buckings, especially if you are going to run propane in this gun. The stock bucking isn't that great and doesnt hold well to propane. And lastly i would replace the stock inner barrel with a tight bore barrel. But overall this gun is easy to tech, and lots of fun to use. Very realistic you cant go wrong. Ive been able to fit real steel stocks, pistol grips, and i dont know for sure but i hear some real steel rails systems will also fit. Overall great gun highly recommend if looking for a solid gas gun.

Price(isnt too bad)
shoots far
Nice ROF
light weight
Steel parts (bolt carrier, bolt catch, dust cover, sling mount,selector)

Mag Cost
Bufferlock isnt steel
Brand is very proprietary
bucking and barrel
