"Looking for a barrel for your KWA EVE-4? Confused because everyone seems to have a different length listed for the inner barrel? Well you are in luck!! You need a 185mm and the Prometheus 6.03 is the perfect choice! This thing really suits the gun well. I have no complaints, neither will you.

"$60 for a glorified metal tube is a lot of money but its for a good reason.

Very accurate, increases range, very durable.

"Buy cheap, buy twice" and this thing will last you a life time.

"I've only used Laylax prometheus inner barrels in my last few builds after trying many different brands. If you truly want the best tight bore barrel you really only have one option, and you're looking at it! The only other inner barrels that come close are the ORGA MAGNUS wide bore barrels but they will require you to go HPA for the best results due to the air volume needed to produce a decent FPS. For standard AEG builds this is by far the best option!

"This is a great tight-bore barrel!

A good first upgrade for beginners, pair it with a new hop bucking if you want to for your first basic upgrade. (I always recommend "Modify Baton flat hop" but there's many options out there)

"This is quite literally the closest thing you'll ever own to a magic wand. It's a stick that performs some real magic. Literally almost doubled my range on my GC16 predator with a purple bucking.

"Fits perfectly on my Echo-1 P90 and with all the upgrades I've added.
(I have Prometheus 6.03 EG Tight Bore Inner Barrel for Airsoft AEG (Length: 247mm), Angel Custom Advanced THOR Complete Hopup Chamber for P90 Series Airsoft AEG Rifles, and Mad Bull 60 Degree Shark Bucking With Fishbone Spacer (Color: Red / Design: Hard)

"Prometheus is the only barrel I will use in my rifles as I believe they are one of the best tight bore's on the market to date. Every time there's a new build in my hands, I can promise you I have a Prometheus inner barrel getting the job done!

"Best barrel on the market, got one in the two M4' I own and in my HiCapa 5.1. Like them so much I just ordered one with my Krytac PDW-M and they make ones that are specific lengths for rifles with odd ball length barrels like Krytacs and the ARP9. If your buying a primary order one of these also you won't be disappointed
by Akash P. on 02/01/2020
"So, I got the 155mm for the Krytac PDW and I gotta tell you. It's the best upgrade that I've got. Of course with the Prowin Hop Up, Modified Flat bucking, and a prommy M120 spring. I'm easily hitting targets at 250 ft. If you need to upgrade anything, get the inner barrel first.

"The only barrel I found that fits a ToyStar (Daewoo) K7 flush to the end without modifications. 318mm barrel length. Sitting perfectly with my prowin clone, need to add rubber oring spacers later for flush fit.

"This barrel is amazing! It is the official Prometheus EG tightbore. (Not a knockoff). I currently have this barrel paired with a Pro Win hop up chamber, G&G green bucking, and R Hop patch by Elvish Tac. It is super accurate and provides amazing range with the combination I used. All of this I put into my Krytac MK2 SPR. My gun now shoots like a dream.
