"Use this V7 cylinder head in all my M14s including my EBR. They work perfectly and are made well. Mates well with a Maxx 21.50mm air nozzle, no leaks at all. Best cylinder head for M14s on the market.

"This cylinder head created a very good seal in my gearbox, I would get this again.

"It was such a tight fit on the MAXX type B cylinder that I had to take one of two o rings off, but the fit was still tight enough that I didn't lose compression.

Its compatible with the Lonex Mushroom type cylinder head, and would highly suggest pairing the two for compatibility and a quiet shot.

"This piece is compatible with G & G m14 ebr???

"Creates a good seal and is leaps and bounds better than the stock one. This is a must-have upgrade for the P90

"Great product. Installed great in my M14 EBR (cyma/echo1), machined well, smooth nozzle bore and, my FPS raised to 410 from 390 which isn't bad. I would recommend this nozzle for those looking to upgrade the stock single oring polymer cylinder head.

"Such a good upgrade! Get this for your Thompson! you won't regret it! This plus a guarder piston head boosted my fps to insanely scary!

"Have this installed in my CYMA M14 EBR. It is a fantastic cylinder head. Great quality and fantastic compression. I only fluctuate about +/- 3fps per shot. Definitely would buy again!

"great upgrade, perfect seal and compression. it also has a fairly thick pad on the back that angles from the middle downward to the air hole giving it great construction to accommodate a silent piston head. perfect construction quality and fitment in my Cybergun F.A.M.A.S. DMR setup. highly recommend

"The Good: Very tough unit, double o-ring REALLY seals that cylinder, doesn't budge, and it fit almost perfect, though a smidgen tight(in which it may just need to rest for a while under pressure and it'll adjust) in the gearbox. A really fantastic air-seal. Currently this resides in my JG G36(DMR Version) Version 3 gearbox.

The Bad: None

The Ugly: None - it's straight sexy purple.

"fit perfectly into my gearbox, does its job, tight fit with an angel customs cylinder which is great and extremely silent with the matching piston head
by Brian L. on 09/13/2013
"Put this in my KA P90. Fit perfectly and will last much longer than the plastic junk that came stock. Good seal and was very easy to swap in. Quieter than before although I am not sure if that's from this Head or the mushroom piston head I put in at same time. Probably both. They do work well together.

NOTE: If you are upgrading a KA P90 with this, use the Guarder High Precision Oil Tampered Nozzle for P90. I tried it with the G&G nozzle and it ended up being too long and wouldn't feed.


Highly recommended upgrade and a good investment to extend the life of the KA p90.

"It's a great quality part, excellent sorbo pad, wicked compression... My only beef is it DOES NOT fit TM style air nozzles... It's a CA/G&G Only!!!!!!!


The part itself is magnificent.......evike please update the description to CA/G&G only!! I had to order a TM specific V7 Cylinder head after the fact from elsewhere
by Travis C. on 05/07/2013
"Put this into a JG P90 and it fit very snugly. It created a much better air seal than the stock cylinder head. paired with the ASG mushroom silent piston head it put my fps around 380 to 390 on an M90 spring. Highly recommended. 5 stars in my book

Pros:
Fit perfectly
Caused better air seal

Cons:
None yet

"Put this in my softair thompson M1A1 and it works great! It provides a much, much better air seal compared to the stock piece so my fps has gone up some. I would also recommend pairing this with the asg mushroom piston head because they work great together!
