"High quality and works as intended

"Great barrel. Does what you would want it to do. I bought this barrel to make my VFC Avalon a CQB gun. I would say that it is a bit pricy for just an inner barrel. Should lower the price a bit, but it’s what you want from a barrel.

"Direct fit to my KWA RM4a1 ERG, it's a bit thicker but fit well in the outer barrel the hop up chamber had some trouble accepting it but with some lube and some finesse I got it to seat only the brass bushing at the end did not fit over the barrel so I left it out I will be sanding down the inside diameter a bit to fit the barrel later to re-install it. The grouping is where this barrel shines man-o-man it can put rounds, depending on the wind of course, on a 3x3 inch target easy at 40 yards especially after the flat hop mod I did with it, on full auto some of the rounds impact in the exact same spot. Great barrel highly recommend it and keep it clean.

"This will fit exactly on a G&P MP5 . Awesome upgrade!

"This is a very high quality barrel. Paired mine up with a Matrix CNC hop up unit and the accuracy has improved a lot. Certainly worth the price! I will be buying this barrel again for future builds.

"Very good inner barrel, increase the shot precision, even for a 9" AEG like the G&G CM 16 SRL, which fits perfectly.
Good choice for upgrade!

"My bolt br47 hop up chamber is a little bit open after the change. But shoots straight, much better than the original 6.0 bolt barrel.
by Jon T. on 05/08/2017
"Relatively easy installation. Along with a new bucking made my Krytac shoot further and have tighter groupings.

"As of right now, the current whether has been crazy and I've only tested this inner barrel a few times, but I've got a good sense on how it performs.

This inner barrel is precisely machined and is very good quality. I accidentally bent my stock Krytac barrel and wanted a replacement that would work with my mock suppressor I had bought with an inner barrel in it. I shot it with the mock suppressor and without it and I was very happy with my results. My stock barrel was getting groupings up to about a foot or a foot in a half stock at about 150 feet or so, which is decent. With this new barrel I am getting groupings 6 inches at 150 feet, which I thought was pretty great. The mock supressor helped a tiny bit when put on with this. This is on my MK2 SPR.

If you're in need of a replacement inner barrel and you want to keep your stock barrel length, this option is fantastic. Only wish they offered a pre rhopped option for this, so you could squeeze a few more feet out of the range.

"major improvement over stock. the pdw is a great little gun for cqb. but it can be improved on. that's where this barrel comes in to play. bought 2 of these barrels. 1 for my sons pdw and one for mine. accuracy was increased dramatically and there was a small bump in fps. can shoot a dime size target 25 feet away. I saw 25 because that is avg feet at nearest cqb field. fps for my son's and mine pdw before avg 320/335 with .2's with new barrels 348/353. buying next a barrel for our spr's.

"Running this through a VFC HK417 with a flat hop and m140. I'm hitting a torso sized target at 300ft 3/5 times. Absolutely recommend this to anyone trying to get the most out of their dmr. While the hop up is more important for long range shooting, a great barrel like this provides even more consistency to the system as a whole.

"These are definitely fantastic barrels; they have an impressive polish and are very stable. They are fairly heavy, so if you want your gun to have more weight in the front, here's part of your solution.

But never again will I buy them. The grouping difference between this and a Modify hybrid 6.03mm is not noticeable until you shoot at 250+ feet, and the difference is hardly noticeable. Of course, that doesn't mean that this barrel is bad at all, it just means that the Modify hybrid is completely underrated. If you play field (like me) and want your gun to shoot the best it possibly can, then get this. If you're one of those guys who has three or more guns that you constantly use and want to upgrade their inner barrels without breaking your bank, get Modify hybrid barrel.s
