The compatibility list doesn't mention these TBs.  Has anyone tried any of these barrels with the stock hop up unit and bucking?

madbull barely work and systema are alright. Prometheus are the best, and the stock kwa bucking fits on them perfectly.

Ask them if you can wait till they get a Prom in, its better to go big now and save your money, than get a half a** tightbore and then have to dole out $60 more bucks to get the better one in the first place.

Never heard too much about Systema TB, but Madbull TBs are really bad, or so I hear.

I would reccommend a Prom, and since that is out of stock, maybe a DB.

If no to that, I'd try a Systema. Their stuff is usually pretty nice. :)

Again try EVIKE. I just looked and they have every prometheus barrel in stock, from 110mm all the way up to 650mm barrels. They have 16 different sizes in prometheus barrels and there all in stock. Evike gives good pricing on all there products too.

Yea, I know Evike is in stock.  If AirsoftGI wasn't hooking me up, I would have ordered it from Evike already.

Thanks for the replies so far.

He can only order from ASGI!

Really, do you people even read the previous posts?

Gosh! :lol:

Heh now that I have that out of my system, I would go with the Systema, because their stuff is generally good, and if you didn't have to return your gun, I would go with the Prom and put it on back order, and if no to that, I would get a DB.

Your choise, good luck :)

the systema barrels are 6.04mm, the prometheus barrels are 6.03mm along with most other barrels.

A 6.04 ID barrel would be just like your stock barrel. A kwa has 6.05 +- 1. Did you check the goupings of you stock KWA? Very impressive for a stock I would say.   If youre upgrading your barrel a 6.03 would be the min ID. 6.00 ID would be max  :lol:

Who makes 6.00 barrels :huh: 6.01 is as far as I've seen them get. With a 6mm barrel you must be cleaning a lot, or it must be jamming a lot.

EDGI makes 6.00mm, I would only get one for a single shot sniper though.

If you take a digital caliper and measure your BB youll see that the ave size is 5.93mm  a 6.00 id barrel would be fine :rolleyes:

I have the JBU and it's pretty accurate. Better than stock and fits fine with stock HU.

I would like to note that you said average. That means on average most bbs will measur just under 6mm, but what about the other bbs that could measure just over 6mm (say 6.02 or so) that would mean that your getting friction which would slow your bbs velocity and would definitly drop your accuracy and would fail as a tight bore. If your buying a bag of 5000bbs your definitly going to have bbs in that bag that are alittle off measurment and with an aeg shooting full auto, some of those falty bbs are going to run through your barrel. If you go up to a 6.03mm you will definitly decrease the chances of faulty bbs. Coming to my conclusion, getting a 6.00mm tight bore is almost pointless for an aeg unless for shooting semi auto (sniper), it totally defeats the purpose of a tight bore barrel for and aeg. DON'T GET A 6.00MM TIGHT BORE FOR AND AEG THAT YOU SHOOT FULLY AUTOMATIC WITH!!!!!
