Review: If you play with CO2, and you can't afford a regulator, an expansion chamber is a mid level fix to the problem of freezing and spiking. If you are a milsim junkie like I am, a magazine is a no brainer upgrade. The folks at BT Paintball were nice enough to create a magazine upgrade that features a three chamber expansion.

The first thing I noticed when turning my remote on was it took a couple seconds for the chamber to fill. This seems to be a good sign to me, since the point is to allow liquid CO2 to expand and become gas before it gets to the marker.

This may have been luck but I didn't have a misfeed all day(nothing to do with the x chamber but still noteworthy), nor did my marker freeze up during rapid fire strings. I also noticed that I had more consistent groupings than prior to installation.

Speaking of installation, the magazine expansion chamber kit comes with everything you need, and all the threaded parts are already threadlock coated. Literally all you needed to install was the hex wrenches they provided and an open end wrench for the fittings.

I think it took me less than ten minutes to take my marker apart, remove the old hose from the power tube, place the new brass assembly in, put the magazine on, and thread the new hose to the asa.

The magazine and magwell are two separate pieces, and there is an o ring that actually seats the magazine into the adapter. it is secured by one bolt.

There are only a couple bad points about the magazine expansion chamber. The first is it is very heavy, I would say close to three pounds installed, and thus makes your marker very muzzle heavy. The second is that you have to remove the magwell and magazine every time you want to open your receiver, which means you have to disassemble and remove the magwell. This is no biggie, but it is one hex and two thumbscrews more than normal. Third, the new hose is a bit too long, so it bows up a little instead of running straight, which means you might have to put some effort into getting it back on.

I don't personally think any of this is a big deal, I think it looks terrific and does it's job.


Conclusion: If you don't mind the weight, and aren't read to switch to HP yet, get this.

This expansion chamber is designed specifically for the BT4 line, unfortunately it doesn't fit the A-5

Although RAP4 makes an M4- and MP5-styled expansion chamber for the A5 that hooks right into where the gasline feeds into the marker.
