Angel Custom G2 SUS304 Stainless Steel Precision 6.01mm Airsoft WE-Tech GBB Tightbore Inner Barrel (Length: 136mm)

"I bought the 225mm length barrel for my WE AKS74UN GBBR, works great, but it does increase the FPS a pretty decent amount, so you may need to buy the RA-Tech NPAS unit if you want to be able to play indoors.

"Undoubtedly superior to the original.
Some aftermarket parts are actually worse than original.
But the inner barrel is a definite upgrade, buy one.
Comes with rubber inserts in the tube held inside a plastic tube, great packaging.
Does not come with a replacement bucking.
Avoid angel custom, they will make your gun lower fps.
Stick with oem buckings or risk lower fps.

"It took a little longer than I expected, to upgrade, but it works amazing! I installed this on my WE SCAR MK16 GBB rifle. This barrel is about 1 cm longer than the one that comes with the gun but if you just match up the groves with the hop-up set thing and have this barrel poking out a little, it still works.
Before getting this, my bbs curved super hard and in various directions. Now they all hit the same place!
Pros: makes your SCAR shoot straighter, further
Cons: took me an hour and half to figure out it's not gunna sit the same way the old one did

"Fits well, and gives me good accuracy for my Krytac Trident PDW. I installed a tracer unit and when I fire on full auto, I get a sense of how much this mod changed the dynamic of my rifle. Very tight grouping even though I bought the shortest variety of barrel that I could find.

"Very well made and precise. Received with no blemishes or imperfections.

"A GREAT barrel! It looks nice, feels sturdy and balanced compared to the barrel that came with my AEG.

** Keep in mind the length of the barrel. 300 mm = 11.8" . So if you're buying a new outer barrel with your inner barrel, measure properly.

"Simply put this barrel is amazing! All of the people out there saying 6.01 barrels will jam under full auto are liars. I have this barrel and run full auto continuously for 10-15 second burst at 24 rps and no issues. I am using elite force bbs for this.

Pros - groupings went from 8-12 inches at 100 ft to 3-4 at 100 ft.
- Fps went up by 12-14
- Excellent polishing inside as well as good crown.
- It actually measures 6.01 exactly.
- Barrel has gold markings on outside to say barrel length and inner size.

Cons- None because this barrel will fit any gun with the dual slots on the sides for different hop up units.

Overall this is an awesome barrel for the money. If you want tighter groupings at range buy an angel custom barrel.

"They the best barrels around, no questions asked! They don't break and are very accurate. I use them in all my guns. Tried many.

Experience: 10+ years. 9 AEG and 5 GBB

Pro: Better consistency than stock barrels, good quality material and packaging. Unbelievable pricing.

Con: None

"I completely love this barrel I have it in my m16 dmr gbbr and using .28 or .30 gram bbs I can hit most man sized targets at 300 ft but that's not the only thing that helps but I'm here to talk about the barrel. OK only one point do I have an issue it that it wasn't completely a take out the old one and replace it with a new one deal. The part of the barrel the bucking goes on was slightly longer than the original barrel so the bucking wouldn't seat where it needed to be as well as the fact the groves wouldn't match the groves in the hop up chamber so I had to measure, grind, polish, and crown slightly so it would fit. I had the proper know how and tools to do this so it wasn't an issue. If you think it's easy as chopping or grinding down the needed material then your wrong being a tight bore barrel any nic, ding or irregularity at one end or the other on a barrel can dramatically hinder the performance or ruin it all together so if you're buying this for a gbbr be aware that modification my be needed and if you don't have the knowledge or know how do not buy you will ruin it and waste $50, it may have been my barrel but why take the risk right.

Pros
Accuracy is increased dramatically (providing you have the proper bucking, bb, ect)
Well made
Durable

Con
Modifications were needed (other than that nothing else.)

"Lets start with the pros:
flawless barrel accuracy
slight (not high) fps increase
amazing range
Neutral:
make sure its for a we gbb p90 or m4 cqb (i accidentally used this on an aeg. MAKE SURE YOU GET IT FOR A GBB)
Evike is so greedy that they cant let go that 60 cents
Cons:
jams a descent amount. but that's expected with an 6.01 barrel, if you get this be expected to clean every day you use this...in fact after every match... and you might want to practice drawing your sidearm out just in case it jams in a firefight
For that one con. i give it a 4/5

"I would not recommend this barrel for a WE gas M14. It was very difficult to fit into the outer barrel; I had to use a hammer. Also, it made the gun horribly inaccurate, even after I fixed the fact the it wobbles slightly inside the outer barrel. I tried switching the hop-up bucking to no avail, the only change that brought the accuracy back was replacing the stock barrel. (All tests were done with the 500fps bolt installed and .36g bb's) The barrel has potential, it's definitely solid steal with a clean look and finish, however it is certainly not "custom" built for the WE M14.

"This did NOT fit the WE M4 SOL (416) as it states

seems too wide for the hop up chamber, and the bucking doesn't fit it either
