"Ive had this for over a year and it was originally purchased to be a backup to my M4 GBBR. However, after seeing the impressive performance for the price, I wanted to continue to use it more when I didn’t feel like using a GBBR or when the weather was too cold. I’ve upgraded since the initial purpose. I got the following budget-friendly options:

Matrix Ported Cylinder
Matrix CNC Aluminum Cylinder Head
Matrix CNC Aluminum Nozzle (o-ring)
SHS CNC Aluminum Piston Head
Maple Leaf 60 degree Super Hop Bucking
Maple Leaf Concave Nub
Unicorn 6.03mm, 370mm Tightbore Barrel
ZCI High Torque Motor
Systema M120 Spring

With the above upgrades and a perfect shim job, the gun sounds amazing and has an extremely fast trigger response. You’ll get 1.44J with .3g BBs. Accuracy is phenomenal and the range is great. I’ve also let this be a loaner for people at the field I play at (we have a small community of players). They are very impressed with it. You can slap a 4x ACOG on this, if you want, and each shot (when sighted in properly) will follow the vertical black line perfectly until it hits the crosshairs. The body, although plastic, is made of a pretty good quality polymer and I don’t fear it breaking. The stock is meh and works, but I suggest getting a better quality one at some point after you do your upgrades.

If you’re hesitant on getting this because of the polymer body and low price, don’t let that worry you. This sucker is great and I highly recommend this as a primary or backup.

"Great gun, have had for over a year. Is lipo ready, and can handle 11.1 V LIPO batteries. thats what i used. I switched over to a 7.4 v lipo because my previous battery died. 11.1 V makes it fire a lot faster. But it also wears down your gun faster. This is a great gun if you want to "sup it up" I swapped the M4 barrel for an alluminum keymod rail. And I put a red dot sight on it, and hoping to do some internal upgrades soon. Shoots far and accurate. Very solid metal gun.

"Amazing gun, i would recommend buying a strong battery because the gun can handle it since it is lip ready. very heavy and sturdy.
