"Love this gun! I've had it for six months now and fielded it a few times and it has done me no wrong. The metal construction is solid and feels great in the hand, and while I'm not the biggest fan how the stock looks, it does its job well, feeling sturdy without wobble and holding longer batteries quite well.

The programmable trigger and MOSFET on this gun are spectacular, and increasing your trigger response to one of the most responsive I've seen in a stock gun so far is incredibly simple. The variable burst fire modes are awesome too, and the binary trigger makes for some great ammo conservation and follow-up shots.

The gun shoots accurate with a respectable rate of fire, and the overall design of the gun screams tactical with a hint of future special forces aesthetic. Personally, I love the slim design in combination with the Calico Jack name and Jolly Roger design on the receiver.

Overall, the gun is incredibly solid and packed with features to enhance the user experience. If you're into the style, there's no reason not to pick one up.

"Great purchase, I love this thing, for the amount of game play I see it does me very well and it keeps up good enough. Very rugged feeling, I have yet to find anything wrong with this gun.

"Just received X4 PDW with forged receiver.

Overall, great gun shoots well despite having to be worn in. (Originally it would shoot all over the place which made it seem like the hop up wasn’t working. I suspect it was because some excess oil was being shot through the nozzle and getting on the bucking)

Love the programmable fire modes.

This version shoots around 310 with .2’s out of the box (not the 380-410 advertised).

Also the QD mounts on the gun receiver (and x4 front rail) do NOT hold QD swivels they will pop out of place. However the stock does hold QD swivels securely in each of its mounts.

Overall a great gun, but taking off a star because of the QD mounts not working and FPS being lower that expected.

UPDATE: another set of QD swivels fits perfectly so adding a star.
