Does the Echo1/Jg G3sg1 need a tightbore???

Does the Echo1/Jg G3sg1 need a tightbore barrel? My fields require AEG's to shoot under 400fps, would adding this tigtbore make the g3 shoot over the limit? Where can I find a good and cheap tight bore for the G3sg1?

I dont think the tight bore would make it shoot over the limit. I havent heard anything about the accuracy, but you should be fine without it. Wouldnt hurt to add it though.

Accuracy is better than any other ACM gun I've tested.

With that said, it can always be improved upon, and a tightbore barrel would certainly help.

Unfortunately "good" and "cheap" don't really belong in the same sentence, especially when talking about barrels, but some good inexpensive options are:
Madbull V2's
JBU

Or if you want best performance but at a higher price:
DB Customs

Id say that JBU's tightbores are relatively cheap. Evike has them for $30.

I put a madbull 6.03 mm tight bore in my E1 M773 and it did not effect the fps all that much, but it did improve the accuracy a good deal, so i wouldnt worry too much about the tight bore barrel pushing you over the limit.

Thanks. I might get a CA tight bore for $40...
