"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.
by Curtis B. on 06/09/2021
"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.
