Gah! I guess I didn't sound serious enough.

Whoever bought it, enjoy her!

I have to respectfully disagree the RAM "Real Action Marker" is not poor quality I have used these for training for many years with very few minor problems. I will agree that the other stuff they sell has less than a stellar reputation ie; shotgun, glock, T-68 series markers but the RAM otherwise known as the RAP4 is a killer little marker.

Both are made by Qwan Wei or Yei or something like that. The metal is questionable on all their stuff. I asked KT to retool the safety lever on the RAM due to problems with the cast iron breaking while doing drills but other than the lever I have had no problems.

The unit is a bugger to tear down if you want to get into the core. I avoid this at all costs but have never needed to get inside of it. As for the S-4 it is a PIA from what I understand.

Is it not based on the VM or Double VM?

Titus, trust me...you don't want one of the s-4s. You would get it, see that it is all ****ed up, then realize you wasted money that could have been spent on your lawyer or your dog and then try to pawn it off on me for the same amount plus shipping.

BtW, PM me your current address. MO is in hand.

Love,

Wel, i do know the RAM4 works (and know how much of a pain it is to get the paint to break at field velocities.. or at all), has a Gen4 one a while back. Neat gun, but like all of Quian Wei's stuff, poor metal, poor machining... Basick low quality chinese goods.

Teh S4 was from before tehy got the hit that is the RAM4, and was vaugly based off of the VM knockoff they had, only really sharing the valve and teh body extrusion. Past that, the middle tube now holds the valve train, with a floating sear out one side of the body, and 2 bolts on either side.

Such a setup could work, but it would probably need to run more off of a tippman floating valve setup, and have an internal setup like a 68 special.

Punisher did a TON of work to one, and got it to function somewhat OK. I had one, that came from Weltman, and then passed to Kindred. I think it worked once when it was new for 10 shots or so.

The S4's problem is that it requires more air to shoot and cycle than the valve can provide. The hammer is massive requiring lots of blowback, double barrels require lots of air to shoot, but the valve is only a very slightly modified VM68 valve.
Playing around with the springs, and doing light modifications to the valve does not really help. As others have stated, the gun will sometimes work, and sometimes it won't. I'm guessing it depends on the time of day, humidity, temperature, and the position of the moon.
If I were to get my hands on one now, I would probably try to turn it into electro-pneumatic or spool valve type marker. As a blowback it is a failure.

The innards without the bolt springs (you can just see one on the right side) (the springs run from the back of the bolts to the back of the marker):

The hammer compared to a Blazer hammer:

Probably already been thought of, but anyone tried running it with a siphon tank for a little extra "oomph"?

The Weltman · 09-16-2008, 05:56 PM

When I had the S4 it fired but had low velocity. I ported out the pathways which apparently diverted too much air to where it wouldn't re-cock. Before I could go further the ASA burst off and if it weren't for the extra screw I would have had a boomerang in my basement. The hole was a large diameter but very fine threads and of course crappy metal.

infamoussmiley · 09-16-2008, 10:03 PM

what if the hammer was lightened? would that improve the recocking? I think the hammer is too heavy.

and yeah, you need a minimum of 800 psi to get the marker to cycle properly and 1000 psi for it to shoot above 270 fps.

Where to find a Chinese S4? Are they Rare.
