EXTREME noob question, but I don't care..

Ok I just got my JG M4A1 a couple days ago, its so bitterly cold out I haven't really had a chance to test er out, so today I stood in my porch and fired off a couple dozen rounds out at the old shed on the property, the bb's are hooking way up, like pretty much every shot, I'm figuring its the hop up adjustment, needs to be turned down? but when i open the discharge port or whatever it is on the side(hop up adjustment port) I can't get that little tool they give you in the box on the adjustment gear. Do I have to split the gun open to adjust or is there something else i can use, i tried using my fingers to turn it but it seems tight, the tool would work best I think....any help welcome, thanks...

I just use my finger to turn it in mine. but yes, you need to tune down the hopup

2. What you're looking at is the dust cover of the ejection port. Right side of the rifle, above the magwell, in the upper receiver.

3. When you pull back the charging handle, the dust cover should flip open. Some don't and you have to open it with your finger nail. A fake metal sheet may be in there...it should slide back, but if it doesn't just push it back gently.

4. Inside near the front, you'll see the right side of the hopup unit.

5. The rear-most dial (and usually the biggest one) is the hopup adjustment wheel. That gear turns other gears that affect how much hopup you have on.

6. Looking at the hopup adjustment wheel. You turn it clockwise for more hopup and counter clockwise for less. The optimal amount will cause your shots to go straight out and then drop. Start with the hopup off...and add a bit little by little.

7. It's FREAKING FREEZING outside...so your hopup rubber has probably stiffened up... When it does that, it will cease to put any backspin on the bbs...causing lousy shots. Too much oil, water, etc...on the rubber will do the same thing.

So...in review:
- it's cold...don't shoot ver 2 mechboxes (i.e. your M4) in the cold
- it's cold...your hopup rubber is too stiff to apply backspin properly.

Best of luck...shoot down in the basement like everyone else...

no my gun is kept nice and warm inside i just stood in the porch for about 2 mins. fired off a few shots is all, anyways so to turn off hop up just turn gear as far as it goes counter clockwise?
