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

"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!

"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.

"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

"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!

"doesn't fit a g&g f2000 stock cylinder if you do get it id recommend a different cylinder in order for it to work with the gun.
