Very nice. Looks like you've kept the weight down too.

Oh man, dont open that, "can o worms"! (i'm just gonna say search to find the drama thread, if you want to read it.) Both the MD and KA pucks have good reputations. MD is the hometown favorite of this forum tho and rightfully so. I would personally start looking at other areas of the firearm as a whole, (FCG, BCG, Hammer drag, Gas port diameter) rather then swapping pucks out. These S12's can be made to run and run reliably with a stock puck and regulator. I hear ya. Just a little research opened my eyes. I'm on the wrong track..and thanks yooper for id'ing it. My m

That looks like it! Any markings on the flat side ? I just started putting Federal bulk thru it, and so far so good. Amazing. I'm using the stock 5rd mag now but am going to try the AGP and Surefire's next. I'm still not confident with the puc. Anybody using the king armory puc ? Any opinions on it? This site/forum is amazing. Thanks guys.

I think you're right. This puc looks just like the picture exept the concave portion extends to the very edge. It most definitly is not marked MD like the photo. The puc's with the extended nipples go against pistons to shorten gas chamber but this puc goes flat side against piston. This was a new, never fired gun. I've checked and this is a 3 port. All 3 are exposed and appear to be at the right angle (towards puc). I've put about 150 rounds thru it so far, and with gas adjustments it has cycled everything except the walmart winchester. I had a buddy pick up some federal bulk so i'll see if i

Great site, lots of info. I purchased a converted S12 recently. Lovin' it so far, but am going thru the FTE low brass thing. This gun came with the gunfixer adjustable gas knob, and supposedly has the MD Arms booster puc in it. The puc looks similar to the pics on CSS with slight variations. The thing is, its not marked MD ARMS. My question is are all MD booster pucs stamped with the name? Is it possible this is an MD ARMS booster puc not marked? I am inserting the puc like it came in the gun, which was flat end towards piston. Is this correct? By the way, Kudo's to Carolina Shooters
