View Full Version : Mr1 expansion chamber???

08-28-2008, 09:29 AM
This has been getting on my nerves. I can't find any expansion chamber for the mr1. I read on pbreview that you need some adapter but i can't find that anywhere either. Anyone ever put an xchamber on their mr1 or know how to do it?

You at least need one of those to use the industry standard threading, 1/8 NPT.

What I'd then suggest is this: http://www.palmer-pursuit.com/cart/index.php?main_page=product_info&cPath=28&products_id=152
It's $100, but it'll be the last regulator you ever buy for your MR1, and cuts out the need for a 3/8 NPT to 1/8 NPT adapter to use normal regulators.

ACI makes one too, and so does Brass Eagle.

^ Bigred is right, get the palmers. The palmers female under the grip is the way to go. It will let you keep the front magazine look of the MR1 and also offer you much more performance then an expansion chamber.

sorry to butt in but is this regulator more for HPA or CO2? I'm new to this and have seen that most of the HPA tanks come with regulators so what is the need for another regulator? and does this regulator go where the original ASA sits? again sorry for barging in on your thread.
