Poseidon Air Cushion 6.05mm Inner Barrel for TM / WE GBB Airsoft Guns GEN 2 (Length: 245mm)

"The best in its class, yet underused


Lots of people in the airsoft world love to rep other inner barrel brands, but this one is the best overall.

The Poseidon inner barrels allow for an unparalleled range performance, and I can give confirmation based on how I built a friend's TM AKX.

The TM GBB AK apparently doesn't hop .28s very easily, but with a 2023 Maple Leaf Autobot and this brand barrel (300mm), it hopped .32s and .28s with no issue. Mind you this was with no mods to the Hopup itself

Now imagine that in a pistol.

This doesn't necessarily mean every gun should have one though, if your hopup can hop heavy BBs already then don't worry about installing this unless the trajectory starts falling early.

"ordered a 138mm specificlly for the We-Desert Eagle (also sold under cybergun.)

Specificlly the Gold Tiger.

The barrels ARE NG3 cut and VSR-10 CUT. Dropped my FPS from 380, to 340, allowing for use indoors on propane.

No downsides. Just works well, highly polished Steel. Nothing much else to say.

"All I can say is WOW! I put this barrel in my We SCAR MK17 GBBR, and what a difference!! I was using a 6.03 barrel before and was lucky to get accurate shots at 150 ft. I'm hitting shots consistently at 300ft with .43 gr bbs with this barrel!!
I was skeptical of a slightly wider bore barrel, but in GBBR's it seems to makes a big big difference. The end crowned channel seems to be the magic with this.I must note, the channel does NOT travel the length of the barrel it is only at the ends where it seems to have been crowned to create this lift channel. I fielded the gun last weekend and was well pleased with the new performance!

"Great barrel. Just installed on a VFC/Cybergun MK17 Scar-H GBB (compatible with the WE system hop up bucking and barrel parts). Used it with the stock VFC bucking and results were obvious- shoots "like a laser". Really an amazing barrel, worth the price and effort. BTW, tried a REAPS A+ bucking and got wacky results- stick with the stock bucking if you own a VFC Scar-H GBB.

"I got these barrels for both my WE M9 Cutlasses alongside the Maple Leaf 50 degree bucking and KJW M9 hop up chamber and the groupings paired with the bucking is ten times better than the proprietary bucking and barrel that comes standard on all WE M9's. I recommend this and give it a good five stars. Note I had to add two slots so the barrel can sit perfectly but that was my bad in not looking carefully at the pictures provided and I the wrong sized barrel for the Cutlass so the 155 mm one might be a better fit.

"*Used the 200mm with a TM Hi-Capa stock hop up unit*

Increased range and accuracy but not velocity. Very nice quality on this.

"Replaced my really bad stock barrel with this. Shoots better of course, but not by a lot. Paired with a Maple Leaf bucking (the real magic in my setup) it shoots absolute lasers in my VFC 416D. I have yet to try anything other than .28s in it.
