Sorry.  Misunderstood you - thought you were looking for the duct around the heat sink.  You find JP's barrel radiator too small?

Yes, it's nowhere near big enough to make a Lewis gun style cooling system.

replaced H buffer with carbine buffer and put in a new carbine spring that was a little longer than the one that was in there...  seemed to run a bit longer before follow through, range master thought I was running a full auto.  And that was with .223, only remembered after I got home from the range that I had m193 in back of closet.   I also had the SDN-6 on it.

Would a carbine gas system run faster or not necessarily depending on gas port size?

I just ordered a JP low mass carrier and an extra strength JP recoil spring.

I am wondering the same thing. I am going to be building a different upper with a mid gas/18" barrel. I would assume that the really important factor is the dwell time, since the recoil of the gun doesn't really begin until after the bullet leaves the barrel.

Alright. Done.

16" stainless 1:7 5.56 barrel mid length gas system
CMC 3.5lb trigger
YHM Phantom 7.62 QD suppressor.



Hopefully I get to the range Thursday before they open so I can take some video and try it out. Cant do "full auto" during business hours or take video/pics. Glad I work there or I would have no place to use this thing.

PSA Freedom upper on super sale $200
Nickle Boron coated BCG(Not pictured because it comes tomorrow) $100
CMC trigger $165
Lower and LPK $100
Bump stock $100
UTG pro handguard $100
Mount and bipod $60

I had the buffer tube and carry handle and suppressor mount/flashhider sitting around. So I did it for about $800

Called it:

http://www.ar15.com/forums/t_1_5/1659807__99_slidefire_stock.html&page=4#i49178917

The bigger issues are:

1 - They're taking PayPal for payment, which will be shut off shortly, as this is explicitly against PayPal's TOS.
2 - They would appear to violate @ least one of SlideFire's 8 patents, and @ 1/3 of SlideFire's price, will almost certainly provoke legal action.

The worst that happens is your CC gets hacked when they fire their IT admin and he leaves their server wide open.  Same thing can happen to you shopping @ Target.  But they already have your CC on file, so you're no worse off ordering a 2nd one.  If they charge you & it never arrives, dispute the charge.

Slidefire's got 8 patents, one of which apparently includes the trigger finger shelf.  Bumpfire Systems may be able to demonstrate in court that the patents are invalid, but Slidefire did not make things easy.

What trigger are you using?

And the pauses between bursts, was that intentional?

Fostech & Slidefire have already tangled, and Fostech has apparently licensed Slidefire's patents, according to Fostech's website.  The Akins Accelerator has long been off the market - though Bumpfire Systems may use that example to try to invalidate some of Slidefire's patents.

CMC 3.5lb

Yes they were intentional. I work at that range as an RO and we don't allow "Full auto" except when closed, and down closer to the backstop to avoid hitting the floor and ceiling. Another employee I did not know took a lane, stopping us from going forward of the line. So bursts were on purpose so as to not get to wild and hit things I was not supposed to. Backstop is 50 yards away. I have no doubt I could just run the whole mag.

Has anyone here seen the tensioned barrel shrouds made of aluminum? They make em for the AR-15. Anywho if someone could add a pressure nozzle to to one and hook it up to a CO2 cylinder, you could dump gas into the shroud and cool the barrel down.
