Plenum home made for Crown

[Mask]

Update .... The plenum for the crown has finally arrived. I tried to mount it on the mechanics (totally disassembled) and I must say that the visual effect is really .... ugly.

In the next few days I will reassemble the crown, with all the necessary modifications and I will do some tests. If I get satisfactory results ok, otherwise I will remove everything and patience, I will try other ways.

Ahhh ... while waiting to reassemble the rifle, I will anodize the plenum in black, maybe it will be a little less ugly.

With and without pressure gauge. Without a pressure gauge, the prechamber is too long, but still acceptable. With the pressure gauge, the length is "extreme. I'm working on the new stock in walnut .... maybe the external crown / plemun union, anodized in black, will be less ugly .... Who knows !!!!!

You really should shoot it and see if you actually gain anything before any other work on a stock or anodizing...

I do the stock regardless of the plenum .... it was already a project I had in mind when I bought the Crown with polymer stocks. The aluminum cylinder occupies the place of the pressure gauge (diameter 25 mm), so there is no variation to do ..... if it doesn't make me anything or if I absolutely don't like it (the fact that it ruins the rifle line I see it already now), I remove everything and reassemble the gauge. As for the anodizing, I have it done anyway, as I now have the crown completely disassembled and the tests will not be done immediately and then it only costs me € 5.

im trying to make the same plenum.. whats your final opinion does it made any difference in energy output and shot count? did you made any other changes on the gun?

Hi Libellule1,

Did your plenum work? This discussion has been quiet quite a while, so I am wondering if it worked and if you can give us any info about it?

Grazzi!
