[Riot]

Update 11/20/24: This is currently shooting at about 275fps.


KPCS Ma-Deuce-A II

Some specs:
KPCS Ma-Deuce-A II body
KPCS Ma-Deuce-A II pump kit
KPCS front block
Benchmark slider 45 frame
CP regulator with gauge
CCM mini rail and on/off
AKA Lightning bolts
AKA bolt pins
KAPP ball detents
Freak bored ANS Phase II barrels
Custom made Medusa grip panels

This above list is taken from an old post... but I don't imagine anything has changed. It is currently set up as a pump and I’ve never had pneumatics on it in my ownership.

I would like to see $1500 shipped.
Member's Price: $1350 shipped.

Why post this when I'm poor

[Snowpuff]

Any one know if it would be possible to chuck an eblade on this thing?

[Snowpuff]

Why not?

[cougar20th]

If I recall from previous builds people have done. Yes but without the eye.

[MullerTime]

I think the big issue with Eblades on these types of builds is it is hard to get the valve to move enough air to fire both barrels at velocity at eblade BPS speeds. You'd probably need a high flowing valve with a stiff hammer spring to keep it open.

[Frmrspec]

A balanced valve will likely be the best kind of option for these.. not so much for flow, but it will allow you to run higher pressures with out needing an extremely strong hammer spring, and crazy high LPR

Playing pump with these is so much fun, get a lot of head turns, questions and eliminations.

Doc does offer his with semi options, so doing eblade I am sure is something he can do.

Surprised this still here.

[Loophole]

Any trades?

[Riot]

Normally, I’d say no…
But I know your collection makes me warm and fuzzy… so, shoot me a message! Haha. Loophole

Not that I think it matters terrible, but can a mod switch this to the Rare/Old section?

Also, bump.

As for the velocity, while it's an issue with a regular 'Cocker, it's understandably even more important on a double barrel: Bore size and bolt porting.

A slight underbore, and better yet, a long bore, are preferable. You want to minimize blowby, without adding too much drag. My recommendation has been to use the newer XL Freaks, or a matched set of 14" straight-bores.

Second, the "wide open" bolts are not recommended. I think Ken set that one up with Lightnings, and those are a poor choice in this case. The idea is- for any 'Cocker- to minimize how much the slug of air coming out of the valve, is allowed to expand. The more it expands, the less energy it has, and therefore the less it can apply to the ball.

Keep the bolt passage the same diameter from the valve, through the body, and through the bolt, and that's about as ideal as you can get. That's how I make the Vee-Twin bolts- and how we used to make the FastBack bolts- and the only time I've had anyone complain, is when they put a bigger bore, "high flow" bolt on it.

This is the way.

Just giving you a free bump because after God knows how many years of seeing these markers, reading the title of the thread finally made me understand its a play on the word Medusa...

[Impactfour]

Oh lawd that makes me feel better

[DocsMachine]

Better, it's a double play.

"Ma Deuce" is, of course, the colloquial name for the venerable M2 Browning .50 cal belt-fed machine gun.

(For those few of you that might not already have known. )

Doc.

[Impactfour]

Oh man, I'd imagine all this creative wordplay has to increase the resale value...
