Maxx Model CNC Hardened Stainless Steel Airsoft AEG Cylinder (Model: Type D / 250-300mm)

"My review is for the TYPE D cylinder.

I highly recommend this cylinder to improve your FPS consistency and air seal.

The advertisement for fitment is spot on. I paired this with a prommy EG barrel 260mm inner barrel. My FPS is spot on at 355fps. and my groupings improved because it balanced out the air for my barrel length.

Very happy with this purchase.

"I bought the air cylinder Type F for my G&G ARP9 to match my inner barrel and the listed parts are in my ARP9 are:

Stock Ver.2 Gearbox Shell
Stock 8mm Bushings
Stock Gear set (shims added)
Stock Anti-Reversal Latch
G&G G2 Double O-ring Air Nozzle
G&G G2 Double O-ring Cylinder Head
Stock Air Cylinder (3/4 port)
Stock Piston Head
G&G G2 Piston
ASG M125 AEG spring
G&G M4 Trigger Switch Assembly
G&G Original 18K Motor
Stock G&G Rotary Hop-up Unit
Maple leaf Mr.Hop Silicone Hop-up Bucking
Maple leaf Omega Nub
Prometheus 6.03 inner barrel (Length 128mm G&G Special Edition)
Airtech Studios IBS Inner Barrel Stabilizer (Model: G&G ARP9)

With the set up I have above I was shooting 326-334fps and with shoulder-wide grouping at 100ft

I learned about matching air cylinders with the inner barrel so I gave it a try and with the same exact set up after switching out the stock air cylinder and installing the MAXX Type F air cylinder my fps jumped up to 392-395fps and when I went to test for groupings I noticed it has about a head-size grouping which I am satisfied with. I plan to change to a weaker spring so I can use it for cqb, I then tested the air seal with it and it was very good with no air leak. Overall very satisfied with the air cylinder and highly recommended it

"Just awesome mine got stolen :(
