Manufacturer DescriptionSubscribe to Reviews on this Product - Edit this Product Listing
The CQB is the shortest and most compact marker in our line up. The CQB easily outperforms other markers in its class in terms of accuracy, range, reliability, and efficiency. Its small size and low price makes it ideal for beginner players looking for a highly menueverable and reliable paintball marker. The CQB can be customized into a full size marker with optional front end kits and tactical stocks. This model includes upgraded aluminum internal components for increased performance and durability. HPA is highly recommended for optimal performance.

Review: Aside from the MILSIG M-Series, all the different versions of the K-Series (ie CQB PRO, COMMANDO, COMMANDO PRO, ELITE, & ELITE PRO) are all the same just with different accessories. With that being said, the K-Series is basically their version of the Tippmann A5 with better material.

LOOKS & FEEL: 10/10

This paintball marker looks AMAZING. I've fired real M4 and M16s before and the look, weight and feel of it is almost the same. Some individuals might not like this because its heavier compared to their usual paintball marker, but its not a big concern if you have muscles!


Almost anything that fits on a Tippmann A5 will fit on the MILSIG K-Series, which is AWESOME! I'm still in the testing phases of the MILSIG Marksman barrel, so the verdict is still out on that one, but so far the effective range (30-40 ft) of the barrel is very accurate. The marksman barrel DOES NOT come standard with the CQB Pro.

The K-Series CQB Pro, COMES magazine fed ready. I can tell you right now that one magazine is not enough for you. You would probably want a minimum of 5-6 magazines on the field with you. This paintball maker is for those who truly want to a MILSIM experience, stressing on tactics, communication & teamwork. This is not your usual raining paint type of marker. If you're not a MILSIM enthusiast this is not your type of paintball marker. However, it can easily be converted to a hopper fed paintball marker. With some slight modification to the Tippmann A5 HE Grip and with an addition of an agitated hopper it can easily keep up with the speedball guns. The current redesigned magazines can fit 19balls instead of 18balls.

The Mobile Air Tank Stock (MATS) is a really nice feature but it DOES NOT come standard with the CQB Pro. The MATS really completes the overall realism of the marker. Running off of a 13CI 3000 PSI tank, I was only able to get ~80-90 shots (5-6 magazines) off that tank, some individuals have reported that they are able to reach 6-7magazines. Trust me, one extra magazine (18-19 more shots) makes a big difference. You can however connect your remote line to the fill nipple of the 13CI tank for addition air if you needed to.


If you know how to maintenance a Tippmann A5 or an X7 you know how to service the MILSIG K-Series. The only difference is, instead of having push pins, they have screws and bolts. The reason why they did this is because it increase the durability of the marking by using steel screws and bolts. Some may argue that this is an inconvenience, but realistically speaking, I rather spend an extra couple minutes to have that durability. They also have a wonderful library of maintenance videos on YouTube.


The reliability of this paintball marker isn't bad but its no Tippmann. I've had some issues with the magazine ratchet breaking down on me, but the customer service for MILSIG is AMAZING and they happily replace any broken magazines for me. The problem is that the plastic nipples that hold the ratchet in place tends to break, what MILSIG is planning on doing is replacing the plastic nipples with metal ones to prevent this re-occuring issue. I've also heard that their cocking handle has a tendency to break on the older versions, but this never happen to me. They've already redesigned their handles to address this issue. I've also heard that the marker has some leaking issues around the o-rings for those who live out on the East Coast of Canada, where its super cold. The problem is due to the O-rings shrinking, caused by the cold climate. They've already release new O-rings to address this problem. It doesn't, however, effect me at all since I live on the west coast. One thing about this company is they actively listen to their customers' complaints, concerns, and demands and adheres to them.
Conclusion: This isn't your usual paintball gun. If you want to deliver loads of paint, go for your speedball guns, if you're a casual player who doesn't want to deal with maintenance work, go for Tippmann. But if you're a MILSIM and paintball enthusiasts this the paintball marker for you. I like to call MILSIG K-Series as the AK-47 of paintballing. Its heavy, loud, and durable. Expect to deal with reliability issues I addressed earlier, but like I said, the company is constantly redesigning their product to improve on its weakness, so perhaps by the time you're reading this, they've already addressed and redesigned the problems I highlighted. Great company, great service, just needs to fine tune their small issues they have with their product
