This is my baby, my CA M24. Right now I think its shooting a little too hot for michigan right now but I'm taking her to get chroned this weekend. By the poor man's chrono I put a hole through the top clean and I accidentilly hit the tab in the process but that got bent into the pop can as well. The one on the bottom obviously is my M4. By looking at teh body one would assume that its a CA, but only the body is CA. That thing is made from like 6 different brands. Ya ya ya, I know its got a battery bag. Oh well ;) .
Some eye candy for ya.

pdi hop-up unit
pdi bucking
CA 300% cylinder kit
pdi 380% spring
harris bi-pod
pd silencer adaptor
leapers 3-9X50mm red-green illuminated scope
and a laser for fun.

M4
guarder infinite torque up kit
guarder infinite torque up motor
guarder shell
high temp wiring
g&p metal hop-up unit
g&p bucking
madbull 550mm barrel (6.03mm)

Um.. How hot did you say that thing is shooting? My guestimate is high 550's, if not 600's.

I never said I knew, I'll tell you this weekend after I chrono it for the first time with that spring. Reason I went with such a stiff spring is because before with my CA 300% i was only get 487 ish with .2's . Which is way lower than it should have been. If its too high I'll just cut some coils off.

A 300% should be shooting 550+, but CA springs are kind of shoddy. That PDI spring I can almost guarantee will be 600+.

If you're getting low readings with hot springs, my advice is check your air seals and make sure it's legit. My advice would be to check all your internals for any hole or spot that could cause an air leak and see if you can't buy a replacement. Chances are good though that your getting a low FPS because of your DB Tightbore, you see. A tightbore (6.04) is the best medium because it allows the proper amount of air and pressure to flow with the bb as well as achieving better accuracy than a 6.08 (stock) barrel.

Now, because you say you have a 6.01, I have reason to believe that because it's so close to the actual size of a bb, there isn't enough balancing pressure to allow that bb to fly as fast as it should.

If you don't believe that is the problem ,then check your cylinder head and piston cup. Those will be your major problem causers for low FPS.

Either way, I don't expect to see you bringing that rifle out to any game in Michigan, until we know it's not shooting as hot as you say.

Well as I said before I'm going to chrono it spyops tomorrow in fact. If it shoots hot I'll cut off a coil or 2 depending on how hot it is. I've taken it apart and inspected the parts many times and I have never found anything that would suggest that a part was damaged and I've checked the o-rings in the hop-up unt and tried several buckings. Problem will be fixed tomorrow or in the next week so you can count on seeing lots of both of these rifles this year.

I highly doubt it's the tightbore causing the problem, unless the barrel isn't broken in yet. DB Customs barrels have a 700-1000 round break in period. If you've already broken the barrel in, my guess is something with the chamber/hop up region.

Dutton, I believe he is referring to the fact that tighter bore barrels actually tend to give a slight decrease in velocity. This debate was sparked back when PDI released their 6.08mm tightbores, stating that they gave better accuracy at velocity, than a 6.03mm or tighter.

Either way though, it wouldn't be the difference of nearly 80fps. Something tells me, that it was just the CA spring.

YourGod, once you get a definitive chrono result, post them up here, then maybe we can help you out, if need be.

Thanks man. Even before though I was getting really nice range. I was dropping people at over 200 feet. Although it was taking me like 2 shots per person thats because I was shooting up-hill and my hop-up was a little high and was being stubborn. I should be able to post my chrono reading around 1:30 tomorrow. Taking a friend to work then getting my m24 chroned then I've got class.

I know what he was referring to, but truthfully, that shouldn't affect the performance that much. Most BBs are not 6.00mm, they are actually smaller, so the smaller bore in the barrel shouldn't be too significant. I have a Dees Customs barrel in my M24 as well, and to tell you the truth, I'm running a cut down PDI 200% spring in it, and shooting 545 FPS, that's over an 80 FPS gain, simply because of the barrel. As long as he's using quality BBs (I've test Maruzen, KSC, Excel, Airsoft Elite, TM, and Straight/Digicon BBs) through my M24 with the Dees Customs.

To me, it sounds like the problem lies elsewhere. It's unlikely that the barrel is truly causing such a problem. That's just my experience with such a tight-bored barrel.
