A US based friend asked me if I can make a horizontal large plenum for his following gun which has longer stock.

Since his stock had enough extra space to support a horizontal plenum, we designed it for the 1st time.

It's for new HM1000X gun that has larger regulator cavity and larger dia for the inbuilt plenum cavity. I don't have this model of RAW.

Some friends helped me and provided me a Huma regulator for the required model. We obtained the specs.

Also some friends on this forum shared some data.

Finally the following horizontal large plenum has been made.

Total added length is around 2.6".

The plenum capacity is 67cc.

Largest dia is 63mm as advised by the user.

There are also high efficiency valves and anti hammer bounce devices to make the complete upgrade package.

There is also a set of hanging plenum and valve and anti hammer bounce device for a UK based user. This plenum is 76cc.

I hope that both sets will enhance the performance of RAW guns to great extent.

Both plenums are made out of solid bar of high grade stainless steel and designed by mechanical engineer for peace of mind.

The real life testing will be done in a couple of days and then these shall be dispatched.

Do they make a shorter bottle for the hm1000X that you could use with that chassis so you could fit your inline plenum and not have to remove the extended picatinny rail from the chassis ?
