Matrix 6.03mm Precision Steel Sniper Tight Bore Inner Barrel for Airsoft AEG (Length: 208mm)

"There barrels are pretty good. You can usually find some of the longer lengths on sale. Ive used a 455mm for an ics ak74m, and the 550mm in an ics l86. Noticed a ~10 fps boost and little change to accuracy however these have one flaw. As the picture shows the window is small. I am not able to fit any kind of maple leaf bucking with this barrel, so I have no idea how some of the other reviews claim that since those contact areas are long to cover an entire barrel window which again this barrel doesnt have. Old technology like prommy or g&g greens can only do so much. The workaround this is the use of a PDI W hold bucking, which I highly recommend for normal use as well; you can read my review on that product page. For both my ics ak74m and l86 they both shoot with the same accuracy and range with 0.28s. Its important to keep track of your cylinder to barrel ratios as well and dont just stick the longest barrel you can into your aeg. 360-455 is the sweet spot in my experience.

"Great upgrade for the Golden Eagle GBBR with the hybrid hop unit that accepts AEG inner barrels and bucking.

"Put this 16" in my G&G CM16. I have a longer outter barrel and Krytac muzzle brake so the inner isn't exposed. This barrel cut my group size in half and functions fine on auto. Very accurate.

"Much better than the stock barrel on the P90, only thing is the length I ordered to match what the site says on my gun is about 30mm too long. Fixed it with a larger flash hider but as a note of caution, check your barrel size before ordering. Regardless its a nice barrel

"I replaced my g&g cm16 raider cqb inner barrel with this one (250mm Perfect size with kx3 amplifier). I have noticed a difference, The barrel itself is a little heavy than my stock and the accuracy/groupings are way better than before. Idk if it�s just me but my gun sounded more powerful and gave me a little pop with this barrell and gave me more pop with my amplifier hehe. I guess you can hear the difference of the quality with Stock aluminum and steel inner barrell. Get this barrel if you are planning on upgrading your inner barrel.

"This barrel is amazing - I play at a CQC field and, but there are long open areas of at least 100 feet, which are perfect for this barrel. I have a regular G&G hop up and my internals are nothing special, but the 208mm has 0 drop from 100ft with .20s. HIGHLY RECOMMEND

"I used this in my XM8 and works well. Replaced a Stock Barrel of similar length and this works well.

"I've had this barrel for a few years now and it performs really well. I stopped using it for the last year or so because I wasn't able to R-hop/flat hop the tiny hop-up window. But recently I picked up the Maple Leaf 70 degree pink bucking with a Maple Leaf Hopup nub, it put this barrel on par with my other R-hopped barrels (modify, Promy). The small window is perfect for the nub, which is designed to curve with the inside of the barrel. I highly recommend this set up for anyone who doesn't want to deal with R-hopping barrels, but wants the same results.

"Install this into my Echo 1 RPK. Now my RPK is a monster BB hose on the level of sniper quality!

"This Barrel is the best upgrade I have put into my M4.
I installed this on my G&G M4 and did a little bit of hop-up adjustment and now it shoots amazing, it shoots like a laser.
For only $25 this barrel will transform your stock AEG

"I cannot say anything else but say this barrel is excellent and is the best barrel ive bought in my years of airsoft

"This barrel is quite nice. I have it as a 10cm upgrade to my AK DMR, and it does the job. The crowning is about half a centimeter, it has two positions for the hop up clip, but has a fairly small barrel window. I can't blame the barrel for making it small, but I did have to lengthen the barrel window to accommodate for my flat hop. Very strong and smooth feel. There is a trademark engraved or something into the forward portion, as well.
5/5

"Great inner barrel! I put this on my JG M4 and i am very pleased with it. But beware, I bought one of these for my Brother's king arms P90 and it doesnt fit very well, make sure you get the right one. Highly recommend this barrel.

"Great product. Easy to install and notice a HUGE improvement in accuracy and a nice boost in fps on my m4. It now shoots better than my sniper rifle. Highly recommend this as an easy/inexpensive upgrade.

"I love this barrel. I wanted to make kind of a long barrel gun and chose this as my barrel. I have it on a G&G Combat Machine with a 190mm mock silencer (which I put some pipe insulation in to hold my barrel still inside it). I also have a M125 spring and a full cylinder on it. I am shooting 380FPS with 0.28g BB's and can hit a human size target at 280 foot with it. Yes I know I only needed 150mm silencer but the extra length with the pipe insulation in it makes it quieter.
