EMG Salient Arms International Licensed Complete SAI GRY AEG Upper Assembly (Length: Carbine)

"Awesome piece to add onto my EMG/Sharps bros Jack. Fit well and very sturdy easy to assemble so long as you have a general understanding of AR construction. Can easily fit a 395mm barrel with no excess hanging out. Parts a bit sticky upon first use but will come apart with some strength. Only real con is the cheap plastic charging handle it comes with so order a new one or transfer over from another gun. I recommend the Krytac Trident M4 Charging Handle Assembly for M4 / M16 Series Airsoft AEG Rifles. Its the exact type you need.

"awesome it fits perfectly my G&G CMRL16 P*STAR JACK

"Excellent piece of kit. fit right onto my old G&P lower that is housing a polarstar gen 3 Fusion Engine.

Rock solid, very well built. finishes are all smooth and part fitment is very tight. no wobble.

Only complaint is that the holes for the set screws for mounting the barrel nut to the reciever threads weren't actually threaded at all. $5 tap and the set screws went right in.

Pros:
Solid
great build quality
light

Cons:
had to tap some holes myself.

Even with the added effort, still a 5/5

*note*
what the devil is the large threading on the included muzzle brake for? I've never seen threading that big on a muzzle device.

"I just got one for my G&P m4 and it is awesome looking!!!!!! I would recommend everyone to buy for the m4 it look amazing buy it
