Matrix 6.03mm Precision Steel Sniper Tight Bore Inner Barrel for Airsoft AEG (Length: 370mm)

"Got this for my field gun, modified g&p. Over all it is a good barrel for a nice price. With a modify flat hop bucking (the soft one) and .25s I am hitting a man sized target consistently at 175 feet, with .28s I'm just making 200 with 6/10 hitting a man size target. My one gripe with the barrel is the window, the slanted design made it near impossible to rhop correctly.

Pros:
Price
In proved accuracy

Con:
Window cut

Overall I think this is an excellent barrel to easily upgrade over a stock barrel.

"For the price, you can't really complain. Does the job, tightens groupings and overall increases accuracy of your airsoft gun. Only reason I give 4 stars is due to the design of the hop-up window of the barrel, which presents problems if using a flat-hop or r-hop. For whatever reason, the stock window has a slant on front/muzzle-facing side, giving a cross section image sort of like this: \_| as opposed to the standard window which would have a cross section looking like this: |__|. This presents a problem with flat nubs, seeing as the angled part of the hop-up window interferes with the flat nub. Not sure why Matrix decided to cut the window like this, but if you're planning on using a flat nub, you'll have to file or mill out the rest of the window for it to work properly, which can present problems (burrs from filing the barrel coming in contact with the bb) if you don't have the tools to do it cleanly and correctly.

"Great barrel fits my spr aeg perfect incresed accuracy

"All In all the barrel is of good quality, I got this to upgrade from a stock brass barrel and the difference in quality Is shocking. The crowning is excellent, very shiny and hard steel and the inside has no scratches or inconsistencies so far that I've noticed. This product increased my accuracy ( noticeably but not a night/day difference) and also noticeably increased my fps in the same manner. All in all if your hesitating to buy this barrel, don't, it's of good quality and does give better performance over a stock set up, pretty good upgrade. But if you do have extra money to spare. Get a Prometheus, as Ive heard those are the best. In conclusion
Budget: this one
Money is no object:
Prometheus/edgi

"pretty good not all that great but still better then most I run this in my custom kwa m16 dmr and it dead accurate up to 120 ft what I mean by that is you can hit a target in the same spot 8/10 times from 120 ft but im also using a maple leaf nub and a madbull hard bucking it brought up the range by 30 ft and fps by 15

pros
helps accuracy a lot
increased range
stays clean

cons
price

"Pros:
Fits well
Accurate
durable

Cons:
Bucking slides on/off too easily, everything else slides on/off too hard
Bucking slot is a bit too short

"Worth the price.
Pros
Improves accuracy
Improves distance by 10-20ft depending on hop up
Improves velocity. My gun went from 350-375
Cheap
Cons
Buckings slide
The hole in the barrel for the rubber nub to go through is really small. I had to file the arms on the hop up arm to set the rubber nub farther back. Took me days to correctly assemble a working unit. Makes the gun not reliable.

"is this is the right size for the kwa M4A1? just to make sure cuz i dont wanna buy the wrong sized barrel


Webmaster: Yes this is the correct size. 363mm

"I think i may have gotten a dud or something since all the reviews are up there in stars which is why I got this barrel in the first place.

Barrel is 2 stars, reason being:
Barrel inner diameter from back to front seems to get smaller from 6.03 to 6.00 throwing the accuracy of this barrel way off OR the barrel is slightly bent. Seeing the BB residue at the front of the barrel prior to exiting literally caked on all sides and no residue from the bbs in the back of the barrel or middle leaving me to believe that the bb started bouncing all over the place prior to exit instead of riding the top of the barrel or trying to squeeze out. Before I found the barrel to potentially be the culprit I tried numerous buckings (Reaps, Maple Leaf, Modify, G&P, different degrees from 60-75, etc) with a Prowin hopup which worked perfectly fine in the same build just with a smaller inner barrel length (angel custom) and same results every time.

NOTE: I didn't measure the diameters with a caliper or if the barrel was bent with a level just going by the results and the position of the outer barrel and from numerous builds I have made in the past with other brand barrels. It is possible that I just got a dud and these are in fact good barrels but the QA possibly missed this one.

Also the barrel was super dirty inside and required a couple runs through it to clean.

The positive thing I can say about this barrel is that it does seem to be made of quality material. Going to be replacing it with an angel custom which is my usual go to. Not about to spend $50+ for an Orga, Promi or PDI.

"Noticed a huge mark inside the barrel when i removed it from the protective tube they use for shipping. Turns out mine came with a long scratch inside the barrel. Put it in my KJW M700 anyway, and noticed horrible accuracy with .43's. I know there's the "break-in period" but this was pathetic. Shots were going all over the place at only 150 feet out. Differences of 10-20 FEET in all directions between each shot. Debating on returning it or just leaving it in the corner, but i'm going to look into Madbull or Laylax next.

Pros:
Price
Steel
Hard to find 6.03 sniper length barrels

Cons:
Massive scratch inside, causing horrible accuracy and making the barrel useless
