Quite a few people locally ask me what is so good about CCM guns, so I explain that they're built to be pumps and that everything that goes into them was designed to be a pump.
I also tell them about the craftsmanship, detail, and customization that goes into each marker.
This article compares the differences between my custom built tremor series and an S6 that you would buy from CCM
CCM S6 with 45* showing 2 pump handle options
CCM S6 with 86* frame
Hand built shocktech tremor series with CCM parts
Tremor Series on top of a S6
Notice the difference in where the ASA sits (different frames)
The S6 on top of the Tremor Series
I do not have any other guns here with me right now, but T2 & S6.5 are half blocked, & there are lots of midblocked guns out there as well.
The only differences in the guns above are minor, they all have all CCM parts.
Below is a simple conversion of older autococker
I see a lot of people who take a random autococker they've acquired and put a pump on it. Then they wonder why its not as smooth & has that farting sound.
If you're going to do a custom pump build, and you want it to be comparable to a CCM gun, you'll need to put CCM parts inside.
Body - the newest CCM guns (T2 & 6.5) are half blocked, they also still make the full block S6. If you're making a custom gun you can pick from a number of rare bodies or custom milled bodies that are either full, half or mid blocked. CCM does custom anodizing but you could also pick a unique or rare body if you want your gun to be even more 1 of a kind. Rare bodies can go for $200-300
Pump kit - The best on the market is the CCM kit, but gat products also has a AT kit that works with a slider frame. My teammate put one of these on his Dark Cocker which was very impressive. If you're not going to put an autotrigger on your gun there are cheaper kits available for like $30
Frame - CCM makes a 45 frame in thin & standard versions along with a 86* frame. If you're going with CCM you can buy it as a kit with the pump, frame, and cam all together for approx $200
Bolt - CCM guns come with the best bolt available. If you build your own its important to have a bolt that matches your gun for purposes of the detentes but you want to find one that is smooth. CCM delrin bolt is excellent.
Regulator - You can decide what you like the most, I'm a fan of the CCM, or Palmer's Stabalizer... if you're having problems with consistency look here first.
on/off & rail - I kinda think the CCM on/off sucks, but then again its all personal preference.
elbows - CCM takes it to the next level with matching 90* swivel elbows, they're nifty for any gun.
feedneck - CCM guns have clamping feednecks but if you're building your own make sure that the feedneck fits your hopper, clamping is always nice.
internals - this is by far the most important part.. and so many people skip this!! you need to balance your springs, that is what causes the farting & inconsistency. In my opinion CCM makes the best internals, as I said before they were designed to be a pump. If you convert your gun make sure you do not skip this step
barrels - match your paint to your barrel so you don't get roll outs. much more important in pump then in semi. CCM guns come with a good barrel kit, otherwise theres a number of different choices out there if you're building your own. Look for a kit with small bore backs.
Now you know the difference between a gun from CCM, and a gun built with CCM parts. Always make sure you're upgrading the internals. Custom built guns can have more character, but if you're building it from the ground up it may end up costing you more then a gun directly from CCM.
A lot of people put a lot of money into converting a gun like a prostock & then by the time they're done with it they realize they should have just purchased a CCM gun from the get-go.... or some other prebuilt high end pump
Its important to know what you're getting when someone advertised that it is a "CCM'd gun" You could slap a CCM pump arm on there with out even putting an autotrigger & call it a "CCM'd" but obviously that is a lot different then something that people have completely replaced everything inside the gun.
My article mainly focuses on putting CCM parts in guns, however I do hear good things about GAT products and there are other custom options out there. I just do not have any experience with them at this time.
