Wow.  Talk about luck.. I can't even find a local shop that carries a SF3P.

Edit for new page



ACOG will be on by the end of the week. Need a 3P.

Missing the barrel. Have another package showing up tomorrow hopefully that has the last big pieces in it. This is for a friend. He's going down the right path, and the wallet rabbit hole.

Do you plan on using a can w/ the 3P?



I have a spare that is kinda fubar'd due to me being a mongoloid, but I asked Mike Mers about it since he's the manager at my dealer and he says it should be fine since the fubar'd part isn't where the bearing surface of the can is.

No, the ends of the barrels are finished the same way as the factory. I would bet ADCOs tools are sharper than the ones that cut the crowns at the factory.

Last I knew, Arms Unlimited had the 3 prongs for $99 with free shipping

Edit: looks like they're sold out right now, but I would keep checking. They pop back up every now and then

Yeah. That's not too bad. I know it's a 10.3 but accuracy isn't effected by the chop etc compared to a factory 10.3?

I'm just guessing here, but I would think the crown HAS TO BE different on a chop job.  I've never seen in person a 10.3 factory Colt barrel, so I could be wrong, but every other factory Colt chrome lined barrel I've seen has the chrome feathering out of the crown and onto the very front of the barrel.   A chop job would have the chrome ending at the bore diameter/crown intersection..........as the crowning cut would remove the chrome.
Now.......I'm not saying accuracy would be affected.........but if the 10.3 factory barrel is machined and then chromed the same way as my 11 1/2" barrels, I would be able to tell a factory from a chop.

I have a colt 10.3.  If no one else is able, I could take a photo of the crown.

For the Mod 0 guns this is true, but I believe factory 10.3 barrels are also in use.

Built another 14.5" upper today with a FN M4 upper, FN BCG , Colt 14.5" SOCOM bbl, SF 4P FH, KAC RAS, and Matech BUIS.  Along with a 10.3" URG upper I built this summer.

I had Adco cut my 16 in 6920 barrel to 14.5 when I had B2. It came back more accurate than it left...

On another note, I bid the CQBR crown adieu! Sold my RIS and am selling my 10.3 DD barrel. Its in the EE if anyone on here is into it I'll cut you a better deal than what I'm asking. Going to build the exact same rifle just in 11.5 with a URX 3.1. Been toying with the idea for a while. I'll be back one day with a Mod 0!

CQBR Memorial...

Not too bad. Better than the factory SAW Colt barrel I bought.
Yeah. That's not too bad. I know it's a 10.3 but accuracy isn't effected by the chop etc compared to a factory 10.3?  


No, the ends of the barrels are finished the same way as the factory. I would bet ADCOs tools are sharper than the ones that cut the crowns at the factory.


I'm just guessing here, but I would think the crown HAS TO BE different on a chop job.  I've never seen in person a 10.3 factory Colt barrel, so I could be wrong, but every other factory Colt chrome lined barrel I've seen has the chrome feathering out of the crown and onto the very front of the barrel.   A chop job would have the chrome ending at the bore diameter/crown intersection..........as the crowning cut would remove the chrome.
Now.......I'm not saying accuracy would be affected.........but if the 10.3 factory barrel is machined and then chromed the same way as my 11 1/2" barrels, I would be able to tell a factory from a chop.


I had Adco cut my 16 in 6920 barrel to 14.5 when I had B2. It came back more accurate than it left...

Crown on the factory vs Crown on ADCO Cut (Both Colt).

Colt barrels cut from 14.5" seem to be the most correct, but I would also bet that plenty of 10.3" Factory Colts have been used.


I'll never sell my Block II CQBR. I'll build more of them actually.

Depends on what you want. They'll cut it themselves to a port smaller than DD's but bigger than Colt's factory .07 if you want. They've found that to be more optimal than .082 or whatever DD is using on commercial barrels.

If you want true mil-spec port size, just add it to the notes you want it at .070".

Yeah. My FSP Railed CQBR has another ADCO cut barrel that's cut almost exactly like the Colt one. I didn't feel like stripping a gun for the sake of a picture though lol.

We had confirmation from DD that they've supplies complete URGs. But given that we've seen surplus barrels show up as well I'd say probably both.

Yes, I'd read about the uppers, but never seen anything related to barrels alone. Maybe the barrels were meant for CQBR uppers but never got used for that. In any case, plenty of people use brands that aren't Colt or DD for their MK18/CQBR builds so I'm not sure how important the distinction between complete uppers and barrels alone really is.

This brings up a question I am sure that has been answered before. Down the line I intend to get a 556RC but in the meantime I am starting to look for a deal on a 3P FS. Can anyone tell me if the 3p needs to be shimmed on a factory DDmk18 upper with a ris ii and a 10.3 inch barrel? And if so are the shims/washers included with the 3p from Surefire? Thanks in advance!
