    Is fielding a CQB an alright idea?

    Here are the facts:

    1. Gun shoots 250-270 with .20
    2. Gun shoots around 100-125 feet

    Conclusion:

    I'm not worried about getting close to shoot people. The real thing that worries me is, can I get people out? Will people feel my hits at all? I don't think so but I wanted to see if you guys have ever fielded a low FPS weapon with success.

    Of course. As long as you got good range and accuracy.

    I wouldn't say good range. Maybe ok range. With 250 FPS I think I would have to use .25 gram BBs.

    Yeah its not good range but if your gonna use something else that has good range and accuracy than it would be good. With that same fps or even lower.

    All depends on the gun. My ICS M4 CQBR does great in field, but that might not be the same as other guns. I was shooting around 300 FPS with .25s and it was fine, not sure how much of a difference 50 FPS will make.

    I guess I would just have to get a bit closer right? Then shot a few times so they feel 3 little pokes.

    What's the field's layout? At my local outdoor field, at the "CQB Town" you typically aren't far enough from someone for a CQB gun to not be effective. As opposed to their wooded fields, where you will find a DMR might come in handy :p

    Everything I have for CQB but no top BDU just a T-shirt then I would use my AGM not my G&P.

    Just watch it when you're shooting through brush or leaves, often times the lower fps guns have a hard time penetrating that. Other than that you should be set.

    You think people wouldn't mistake it for a bug or just something? If so then I'm going to be fielding my G&P this summer.

    People who "mistake it for a bug" are cheating. You shouldn't have a problem. A lot of it will depend on your field. I mean, if it's cramped quarters, I don't think it's a big deal. They should feel it.

    I think you have a good point there. I hope people call it but where I live sometimes people don't. I guess I just have to spray them. It will not hurt them because my gun is sub-300 FPS. Just would make a lot of noise when the guy gets hit.

    My low powered MP5K (.9 joules, not much more than your gun), is actually my most effective field gun. Just upgrade the ROF if you're worried about people not feeling the hit, once you go past 30rps, people will feel, or at least hear the hit anyway.

    My gun is shooting about a solid 20 RPS. That would be decent right? I would also bring my AGM as a backup if there are a lot of cheaters. Just have to deal with the insanely low RPS (14-15).

    Off topic but I would like some help:
    Should I buy a nice pistol and mags with all my money. Or should I buy upgrades for both of my guns. Or do both and buy a KJW with one extra mag then get a EO tech and some new motors and gears maybe?

    Once more depends. If your style is such to where you would actually pull out a sidearm, super. For me, however, I never end up using mine. Also bear in mind that regardless of what type of bb you shoot, it's still got the same level of energy behind it, so it will hurt the same. (Ex. Would you rather be hit at 200 fps by a ping pong ball or 10 fps by a bowling ball?).

    That's what I thought but I was proven wrong. The momentums are different. KE=.5M*V^2 and momentum=M*V.

    Edit: in the picture I find the Velocity for the .20 knowing the mass of the BB and the same TE. I then use the same velocities and masses that show the .25 to have more momentum.

    Energy is distinct from momentum, but I understand your point. The .25 should hurt more.

    I know I also messed up on the TE. The TE should be 1,250 but the rest of the equations work out. Same numbers for everything but now TE is 1250.

    What is TE?

    A .25 hurts more because it retains its energy for longer than a .2, so when it hits you, there is more energy than a .2 at the same muzzle energy.
    It is not because it has more momentum.

    TE is total energy. Retaining energy longer is because of its momentum. My math proves my point perfectly. Do it yourself. If I'm wrong then show me (not trying to seem rude). They have the same kinetic energy but different velocities.

    Physics debate round 2. Looool.

    Edit: the reason they have the same KE is because they have the same SPE (spring potential energy).
