Trinity AK-47 Expansion Chamber A good product and good look

Out of the package the expansion chamber came with a 45 degree elbow and very generic instructions. An aditional hose was needed. I got an 8 inch hose and it really needs a 6 inch hose for the a-5. It works, except instead of a straight run, it bows downward.
Installing was fairly straight forward even with the very vauge directions. This expansion chamber will work with having a dual trigger installed, as there is a notch in the back of it to allow for the proper clearance. This was a very thoughtful and needed feature. Remove the stock hose from the tombstone and the bottomline. Removed the 90 degree elbow from the bottom line adapter. Install the included 45 degree elbow (unless the hose you buy has a flared end in that case the existing elbow will work.) Install the hose and fully tighten it. Attach the expansion chamber to the tombstone and then install the tombstone and chamber into the gun. Adjust the alignment of the chamber and tighten the set screw.
I used the expansion chamber today in about 70 degree temperatures. I would crono with a freshly filled bottle and my shots were very consistant 273, 276, 275. After playing one game and the bottle stabilized, I was still shooting nearly the same speeds with exceptional consistancy. I used the auto responce mode and got into some very long drawn out firefights throwing alot of paint. The tank chilled, but the expansion chamber never did. The gun shot very consistantly and with no problems.
Overall impression was very wonderul for this product. It helped maintaan good consistancy even under adverse conditions. The cost was only $20 more than other standard style expansion chambers. It adds alot of style to the gun, and the front grip can still be used when slid all the way forward.

Here is a pic. Its on my BT-16 TACTICAL. It looks cool if nothing else. Since I now use air its useless but I get a lot of "wows" about it.

Absolutely beautiful, a friend of mine does that.
I have one of these, replaced it with a male palmer reg, my A-5 doesn't look right now.... :-(
if you used a fem palmer reg, you could also use this, which would make the setup look alright....which is what i'm gonna do!
