Matrix 6.03mm Precision Steel Sniper Tight Bore Inner Barrel for Airsoft AEG (Length: 250mm)

"I have bought this two times both times I have bought the on sale extended barrels and cut them down to size with a drill and brass pipe cutter. With a crowning tool as well
The first time I used this barrel with a shs hopup rubber and it worked wonderfully. Straight as a laser

Second time was a little more difficult. I used a maple leaf super, but the hop window was bent inwards and was jamming bbs. It required some filing down in order for it to fit. But after that great results

All in the the barrel is very well made and may require some modifications to work.
Would still recommend if you have the tools and time

"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

"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.

"Well sense no one else has written a review I will. I put this barrel in my Elite Force CQB and love it. It increased my FPS about 15 and range so I can hit a human size target at 250 foot. When I checked my barrels inside it was 6.02mm. Not a big deal. I love it. Just clean it before you use it, all of them that I have gotten have been very dirty.
