Peer Editing on my JG BAR 10 upgrade plan

[erric288]

Hey, I've done a good amount of searching and I have composed this plan based on a "less than $200" budget (including the price of the gun).  Yes I know that isn't much leaving only $100 for upgrades ,but I'm not looking for extreme performance so I think it should be enough.

Here are my goals: FPS of 400-450+ and an effective range of 165-180+.

Here the plan itself: 1.) JG BAR 10 scope package: ~$130
                           2.) LayLax 430mm 6.03mm tight bore barrel: ~$60
                           3.) DIY mods which include: teflon taping the cylinder head threads, wash and dry the hop up bucking, electrical tape the cylinder head nozzle, the "sproooing" spring mod, and I think that's it.
                            4.)Anything else I missed or that you know of that are relatively cheap or free

So, will that plan give me my desired results or will it fall short?

Also, if there is something else that you guys know of or something that is wrong about the plan please call me on it. And if you have the time, say your set up and the resulting performance to steer me in the right direction for future upgrades.  Thanks for the help!

get a new hopup bucking.

[The Crimson Falcon]

First off, don't use e-tape on the nozzle.  Use teflon tape, and paint some fingernail polish over it to make it a more permanent mod.  Noobies cylinder slit mod (lengthening the slit) is actually quite easy, and very effective.  Cut down the airbrake, and use some thin wire to make a spring spacer.

I wouldn't use the Laylax barrels.  I never had decent results with those.  Get a decent 6.01mm tightbore.  And, don't forget to get some top quality ammo.

[nickswimsfast]

Go with a PDI 6.01 or Edgi 6.00/6.01 barrel, make sure you run high quality ammo as well(SGM, bioval, madbull). The goals you set forth are obtainable for a stock gun, it may take quite a bit of tweaking is all. (the hopup specifically)

[erric288]

So, the amendments to the plan are as follows:
                       1.) New hop up bucking: maybe this one: (http://www.trinityairsoft.com/p-327-hop-up-bucking-fire-fly.aspx) the hard VSR bucking
                        2.)Use teflon tape instead of electrical tape on the cylinder head nozzle (can you explain to me why and what kind of nail polish to put on the nozzle), lengthen the slit on the cylinder (though it seems a bit difficult to do, what do I cut it with and how would I keep it exact?), cutting down the air brake (simple enough to do), and make a spring spacer using wire (what exactly does the spring spacer do? and what type of wire would I use?).
                        3.) get a 6.01-6.00mm barrel (I'm not sure where to buy those)
                        4.) I was planning on using Airsoft elite .28gram BBs

So, with a little explaining or some links to explanations this should do it. Thanks again for all the responses.

[Nitro maniac]

I saw on here a while back about tappering the cylinder head. That would probably help a lot. Also you might even want to get an scs.(Never used one but have only heard good things about it.)

[erric288]

What exactly is an scs? Also, if you have them could you guys give me links or some explanations on the DIY mods because they are scattered and unclear. Thanks.

[Shredder]

With stock JG BAR 10, you can achieve around 420+ fps without buying anything. There's also no need to change the bucking... Just visit my homepage at http://shredderscs.proboards.com/ and some of your answers will be found there.

...Also follow what TCF suggested/recommended for he knows what he's doing.

[erric288]

Well, I'm not only looking for fps ,but also accuracy to 185+ft. So, fps should be relatively fine stock with the teflon tape mods, and so on that has already been said. And the accuracy portion will be helped by the 6.01mm tight bore barrel. I don't feel comfortable cutting the air-brake because it really only gives you 30fps and ,based on shredder's results, increases the inconsistency between shots.

FPS: Stock: 385
After DIY mods: ~400
After tight-bore barrel: ~420
All using madbull .30gram BBs

And again I'm not all that sure on how to do the DIY mods. For example, I don't know how long the teflon tape will last on the nozzle or exactly how much to put on. Or the "sprooing" mod where you put tape on the end of the spring. How much do you put on? And the spring spacer mod, I'm not even sure what that does.

And if you guys know of any links for where to buy a PDI or Edgi barrel please post them. Thanks.

[Ghillie Man]

a couple of a spring guide spacers wouldn't hurt either.

[erric288]

how do you make them?

[CottonTheMoth]

A spring spacer is simply something used to put more tension on the spring which translates to fps. Wire wrapped around the base of the spring guide will make it so that the spring will be more compressed, since instead of resting all the way back to the spring guide's base it will have something in between it.

Regarding the teflon tape mod, fingernail polish is just a kind of prtective coating in this case. It's like putting clearcoat over your gun's paint job to protect it and make it last longer. The fingernail polish will dry and fix the tape in place. Personally I applied superglue with a tiny brush in layers, rather than using teflon tape. This evened out the scratches on my nozzle and probably did increase fps.

A good mod to do is to taper the cylinder head. All you do is put your cylinder head's nozzle into a drill where the bit would usually go (should probably cover it with some tape for scratch protection). In my case I used a dremel instead. The nozzle wouldn't fit into the dremel so I flipped a drill bit around, wrapped it in a bit of electrical tape and slid the nozzle over the taped bit. Once the nozzle is spinning, hold up the rougher low grit sand paper to the cylinder head's rear hole. Once you've tapered it, use a smoother higher grit sand paper. The results come slowly but when you're done you should have a smooth entry point for the air. You'll get more fps and consistency out of this mod, though I'm unsure of how much. My air nozzle had a noticeable metal imperfection jutting into the air path and this mod allowed me to remove that as well.

i have 3 bar10g's all with 9ball hop bucking complete EdGI upgrades sp02 springs 6.00id ported bull barrels
all clocks at 630-690fps all used for reviews only and marksmanship tourneys.
i make my guns so far and keep a close track on them.

on a stock set up the most i made was 440 fps on a 435mm stock barrel. doing airbrake mods this could even go higher if i use a longer barrel. the cojmpression is perfecr no leaks but it caused over volume. to compensate a longer barrel is needed or use a heavier BB say .25-.28g

[CottonTheMoth]

You should really be using .25's stock at the least. With DIY mods .28's are the minimum by my standards. (Oh,or bioval .27's )

[erric288]

I only need about 450fps.  I'm thinking of sending it off to on3_sh0t for him to do the DIY mods because knowing my I'd end up drilling through the cylinder head lol. And then for actually upgrades I would install a 6.01mm TBB and a nineball bucking so that would bring me up to the point where I want it.  I tried the biovals in my old M4 a while back and they worked pretty well and I couldn't find any bbs with imperfections. I think I'm going to use the Madbull .30gram BBs though. After all is said and done I think the upgrades are going to cost about $150-$180. Add the price of the gun and BBs it comes out to $280-$310. But if I wait for the barrel and bucking it will cost $180-$210.  So, I think I got a solid plan now. 

[CottonTheMoth]

That sounds like a good plan then. For the range you're wanting, the small air bubbles in madbull bbs shouldn't pose much of a problem and you'll benefit from the weight, as well as save money. I love my nineball bucking to death lol. If you're looking to make your gun any quieter, utc_pyro makes sorbothane dampening pads. I had a good experience ordering from him.

[erric288]

If anything I might go out and buy one of those silent cylinder heads that come from premade(not home-fabricated). But I'll keep utc_pyro in mind though.

STEP ONE COMPLETE: I purchased my JG BAR 10 (scope package) along with the .30g Madbull BBs just a few minutes ago. Both items are in stock so it should be a relatively quick delivery (from ASGI) even though they are in California and I'm in NY. Next step is to begin the upgrades as previously stated in this thread. Thanks guys for all your help.

[MarineSGT]

And, don't forget to get some top quality ammo.

I think I'm going to use the Madbull .30gram BBs

Why Madbull .30?  I would understand if you were going to the .36+ for weight reasons, but if you are getting a .30, then use SGMs @ .29.  They will work wonders for consistancy and blow Madbull away.

[erric288]

Because .29 SGM's aren't sold at ASGI where I could get 10% off and free shipping. And I'm concerned more with breaking it in and getting used to the new rifle and I thought that the .30s would be fine for now. I'll get them when the Madbull BBs run out. Thanks for the advice though.

EDIT: I stop by Hot spot airsoft after I go through the Madbull BBs and get 500! for $20! Gosh, that's expensive! That's 4 cents a BB.

EDIT#2: I'll also pick up laylax M120 spring to give it a little bit more fps without killing the sears.

Maybe you should have a read through TCF's thread regarding cost per round.  I never believed a sub-.30BB could out-perform something .30 or over.  Take your cheap rounds for a discount and shoot 3 times as much to make contact.  Put that into the mix and the more expensive BB will be equal if not less expensive.  It took me a while to get it, but it makes so much sense to me now.  I personally apologized for all the time I did not believe people about this and do not make the same mistake that I did.

The BB is not one area AT ALL you want to cheap out on.  Take my word on that.

Give them a shot and it will greatly improve consistancy.

If you can't find SGM's very easily, Bioval BBBMAX .27s are supposed to be equal to or better than them, and cost a little less.  I'd try those out.

[erric288]

I've tried the .27gram biovals before in my M4 and it helped my range and accuracy a lot. The SGM .29gram BBs are expensive ,but I get what your saying(the more that hit the target the less you need and the more they are worth). Maybe for target shooting I'll use the .27g and for actually games I'll use the .29g. But I'll see which one is better and figure it out from there.

Here's where you can get pretty much the best barrels out there. 

[erric288]

Yea, that's were I planned on purchasing the 6.01mm TBB from. They seem to be among the best.

[erric288]

New Idea: Could the stock JG BAR 10 sears handle a SP120 spring for more than ~650 rounds? Also, this will give me about a 20 fps gain right?(380-400) So that plus the DIY mods which would give about another 40fps totaling to 440fps. Then with a firefly bucking and Edgi 6.01mm TBB which would give me about another 20fps would total 460fps. Now could that get me an effective range over 200ft? This of course is after everything has been cleaned,re-lubed, and tuned(mainly the hop-up). So, what do you think? Oh, and sorry for the double post since this is like an update after the thread was pretty much dormant.
