Sean, As usual I can never find anything when I need it. There is a list of definitions posted here somewhere. I just wish I got mine they way you did - on the job. Thanks for posting here, Doug

Sean, Thanks for the input from someone with experience. Congratulations on your RKI status. Former U.D.T. WANNABEE, Doug

Thanks Mike, I actually prefer my little bolt as I have plenty of spares(1960's American hardware). I got some more spare full-auto sets in August 2010 thanks to your posts about RSI selling out. Do you have any 8mm hollow pins you are willing to part with? Doug

Greg, Sounds like you're still in business. Hooray! Doug

David, I have one in both my 1903 nickle oilers(no tag). Glad to see that Uncle Sam used to believe in "one size fits all". Great Document! Doug

Greg, If you have any more paracadutisti tricomps save one for me! Sending you a PM and an email too. Thanks, Doug

Echomachine uses the same handle on www.gunbroker.com He has one listed right now #287042827. It looks very nice but has no floor plate for the pistol grip. Last time I checked ebay they had them listed (floorplates) type in "bm59". Doug

My frankenstein barrel's muzzle.

Steve, I sent an email directly to you. The paracadutisti tricomp requires a special barrel that leaves the barrel's muzzle protruding about 1/2" beyond the end of the gas lock. (I'll try again to get a pic with my explanation.) There are posts here from a few years back where guys have blown the tricomp off the barrel because they don't have the muzzle protruding and sealing with the QD tricomp. You may also get cycling problems by not having the gas cylinder aligned properly with the barrel gas port. MY barrel is a modified tanker barrel that I ran the gas lock threads back on with a 9/16" x32 tpi die,relocated the gas port hole and gas cylinder slots, so I could run the quick detach setup. I use a large paper clip that is bent up to locate the gas cylinder so that the barrel port is centered in the gas cylinder expansion chamber. My barrel is a home-made job, but your PB barrel should have the gas port centered with the gas cylinder as far back on the barrel as it will go, screwing the tricomp down to contact,(on my PB barrels the tricomp goes less than 1/2 turn past alignment for the gas plug), backing the tricomp off to align for the gas plug and tightening it very tight with a hex head wrench.

Hello Steve, I'm trying to attach a picture of my select-fire with the quick-detach installed. I have 3 QD flash hiders and 2 mounts. Sarco had a QD that had not been demilled on their website in April 2001 and I was lucky enough to get it. The quick detach collar has what I guess are 2 tensioning cuts: one on top and one on the bottom. The collar on my issued QD is pinched in on the lower cut and allows the GL sight to almost hit vertical. I am guessing unless they made a slightly altered unit for the QD flash hider, they put the grenade sight up,dropped the QD on and smacked it with a mallet to get a "custom" fit. Doug

The little rectangle has a 45 degree right triangle milled into it. It is a selector lock. The left side of the receiver is milled for it. With the 45 degree angle positioned to the rear, the selector switch is locked in semi-auto. Flipping the rectangle 180 degrees puts the 45 degree angle to the front, allowing the selector switch to move forward(full-auto) and backward to semi-auto. The little silver circle is the pivot shaft for the sear release lever. The receiver is drilled for it and it looks to be welded in place and ground smooth on the inside of the receiver. Doug

The pin was bent at 45 degrees just above the collar. I tried to straighten it and of course it broke. There is a well milled in the stock for the plunger to drop into. It may have caught on this while being assembled. (I think it was damaged during manufacture. Over the years buying parts from RSI, I would usually get at least one defective part when ordering more than one of something.) There is a dimple milled in the receiver bottom to help keep the plunger shaft vertical. You can see my replacement bolt isn't vertical in the picture. Just something to pay attention to when dropping the receiver into the stock. I have 4 thousand rounds through my modified sear trip lever, so parts can be salvaged.

Ross, Thanks for the response. Doug
