Internal Upgrades for a Rookie

[frapso]

I have a G&G Top Tech CQBR. First on my list is a 6.03 tight bore once I get the suppressor to cover it.
What other recommendations do you seasoned-vets have for a beginner like myself? Thanks!

I'd leave it as is for now, so long as it is shooting an appropriate velocity to game (eg. 350 - 420 FPS). Guns are best left in factory condition until something breaks, and adding upgrade parts to an otherwise stock mechbox usually precipitates trouble.

I would reshim, correct angle of engagement, and regrease the gearbox. Simple things like this will prolong the life of your gun, and are also the essential "upgrades".

If you want to get more fancy, I would suggest looking into the rhop, as it gives the most performance for the price (more performance than a 6.03 TBB would give).

The cost of having a RHOP installed by someone with skill is several times more than a tightbore barrel and it's not a DIY project for a complete newbie.

With guns nowadays I wouldn't even bother re-shimming, making AoE adjustments or re-greasing unless it was some unknown ACM brand. Major brands leave it alone.

It's not <2006 where absolutely everything coming out of China is total garbage. The quality of materials and construction has vastly improved.

+1 Don't fix it if it ain't broke. Or you're being severely outgunned on the field.
Now why on earth would a retailer of airsoft parts tell you that?!! Because we want you to learn not only as a consumer but also grow as a player.

G&G's TopTech line is usually pretty good out of the box.

shoot it till it breaks or unless something is really wrong with it. TBB doesn't do you any good if you fuck up an already wonderful airseal. my g&g max m14 still has the factory hopup rubber and TBB barrel and it shoots amazing.

I disagree with that.Appropriate starts at 280 and anything beyond 380 is really not necessary.
Also more and more have I not given a crap about tight bore barrel because their utility is, all things considered, pretty inexistant for airsoft.Grouping is pretty much the same and fps change is useless.

I've read of many r-hopped stock 6.08 brass barrels being just as good as r-hopped prommy barrels, so I'm not surprised at your findings. The difference in any barrel improvement lies in how smooth and consistent the bore is through the length of the barrel. I have a madbull 6.03 and a prommy 6.03 that shoot the same as well.

Going off traditional Edmonton area velocities, we run up to 425FPS Full Auto and 500FPS BA, with ~390FPS being the norm for most outdoor AEGs here. All depends where you are I guess!

If you're doing the barrel, change your hop rubber while you're at it. Firefly or PDI W hold are 2 good choices. Just make sure you put it in straight.

[ThunderCactus]

8-20$ hop rubber makes a world of difference. PDI-W or firefly

Is r-hop really that good? I considered buying some but I've read the install can be really difficult

[lurkingknight]

it's not hard to figure out the install,, it's rather tedious though and you need tools of the right shape. You have to sand, cut and file the silicone rubber patch to fit your barrel, and you have to sand, install... try it out.. take it apart... sand... install, try it out.. etc until you get the results you want.

Having a gun that facilitates easy hopup unit assembly and barrel installation helps a lot to get the patch installed onto the barrel so it hops correctly. Once you have a matched patch to the barrel, you permanently glue it in place so you can drop that barrel into any gun.

essentially you need about 50m of open space and a target and if it's your first install, about half a day to get it going. The r-hop should be installed AFTER you address all airseal issues though. If you can get a gun sealing and shooting consistency with less than a +/-5fps variance, you'll see the best results in an r-hop install.

When you don't have that consistency, you'll have a harder time dialing in the patch.


If you are lazy, just get some flat hop rubbers. They fill the void between rhop and standard bucking. The r-hop still requires a shaved sleeve like the flathop sleeve to seal the barrel to the nozzle.

Speaking of which, how much are people charging for R-Hop installs?

[Styrak]

I wouldn't be surprised if the Toptechs already come with tightbores stock. In any case they're excellent guns, I have about 6 in my store right now.

Before you do anything, use it in a game or two. You may be surprised. It always boggles the mind when someone buys a new gun and immediately wants to throw money at it uneccesarily.
