The Sonic RED Valve is now available with the new RED cupseal! Features include:
-Optimised flow dynamics for incredible performance - your operating pressure will be lowered and you gun will sound better!
-New RED Cupseal seals down to 0psi!
-Surface hardened for durability
The Sonic Red valve comes complete with valve, valve stem, cup seal and O rings. It's designed to transfer the gas smoothly through the valve into the marker for maximum efficiency.
The MACDev Red Valve is newer, so it should be commonly available, both new and used.
> Larger Inlet/outlet
> Good Cup seal
> Double O-ring
>Front O-ring is a bit large
The Red Valve is a good investment for any bushmaster, it has a high flow inlet and outlet. It allows the marker to use less air per shot, and while actually increasing the velocity of the marker to a degee. Before I put the Red Valve in, I noticed that most of the surfaces where round much like the LT Valve from palmer, this is ment to decrease the turbulence caused by moving air when it hit a flat surface. From what I have heard and know is that the lower turbulence, the better the air flows and that means better performance in the increase of velocity. And the Red Valve has has two O-rings on it so it has a far tighter and better seal the stock valve could ever have. The noise the marker makes now when fired is considerable different now, instead of that loud crack noise the stock valve make it has a low pop noise. The cup seal is excellent, it has never leaked on my marker, never.
The only problem I had with the Red Valve was when I was installing it. The front O-ring was a bit large and made it very difficult to put in. The O-ring got pinched when it finally got in and, I pulled the valve out and took the now snapped O-ring off, and put a new on on from the stock valve. After that the Red Valve went on with no problem.
This is a good buy for any bushmaster, if you are looking for a new valve the MacDev Red Valve should be on your list.

very consistent, cool color, very durable finish, seals perfect, easy to install, perfect valve
kinda pricey for a valve but its cheaper then alot of others no problems
I don't know what happened with the other guys but there's nothing wrong with mine I 've been using it for a year now and I've had not problems at all much better then the vapor valve at everything I think its the best valve you can buy for bushmasters works great i can't say anything negative about it. I don't know whats up with the other guy though, you should've contacted macdev as they fix all their problems immediately, unlike vapor who never fixes their problems.
buy it don't go out and waste your money "vaporizing" your gun because thats all your doing to the performance, vaporizing it because your gun will suck afterwords just get all the macdev stuff and have a perfect gun

On paper, and in initial use, this product seems to be a perfect upgrade for the BM2K.
It offers Higher flow porting, better port finishing for reduced turbulence, a very reliable cup seal, a highly wear-resistant coating (my valve guide STILL has no sign of wear whatsoever), and a less restrictive valve pin.
It has an Achilles' heel, however. The amount of threading on the end of the valve pin that holds the cup seal in place is woefully inadequate. It would repeatedly loosen up during the course of play, contributing to velocity fluctuations. But more importantly, with each smack of the ram, the steel threading of the valve pin was slowly obliterating the brass threading of the seal cap. I tried gluing it in place, but to no avail. The repeated blows would break down any glue I used. Over - tightening the cap didn't help either since there were barely enough threads (no more than 3) to hold it on in the first place, and I didn't want to strip it out.
One little piece of bad engineering wrecks an otherwise perfect product.
I've given up. I machined my own cap out of steel, but it still won't stay put. I ordered a new Check-It valve to replace the RED. Check-It, AKA, and Vapor each offer their own improved valve for the BM2K. I would recommend considering their products over the RED valve.
Easy to install. Works great. Seals even at extremely low pressures.
This is a pretty good investment if you want to increase your air efficiency. It's fairly easy to install. You have to be careful that you don't overtighten the screw to hold the valve in place. Also, make sure you're paying attention (unlike me) when you install it......don't screw it in where the ASA screws in at, it's the same size holes. Good thing I realized it before the loctite hardened!
It seals even at really low pressures.
