Best Suppressed SBR Ever????

[C4IGrant]

Grant,
i have read this thread so many times i have confused myself. I have purchased a Daniel Defense 16" hammer forged barrel and had it cut to 10.5 but left the gas port small. I have installed it and won't get to shoot it till Sunday. So it should function fine with the can. But without can it won't lock back UNLESS you use the LMT enhanced carrier? TIA

Correct.

flanntastic,

Please let us know how it works out.

I have been thinking about cutting down a daniel's barrel also.

It would be great to hear some feedback from someone who has already done it.

Grant,
I was commenting in another thread, your idea of using the MK556K to help reduce blast baffle erosion is a great idea, it becomes the wear part like a OPs break. I changed my dedicated upper to use the MB556k. Can't wait to play with it this weekend.

I had been considering trying to chop down a 16" bbl and do the same thing myself (leave the gas port unchanged), but I was unsure how it would work.
Would be nice to know the preferred OD of the gas port hole, in order to be like Grants and run CLEAN.
flanntastic,
Do you happen to know the OD of the DD port hole?

i had adco do it, Steve knows his stuff, i wanted a lighter profile than what i had so the DD hammer forged barrel was the profile i was looking for. I was told by others that the carbine size hole was as small as i wanted to go.

The .063 GP size is pretty small, but you can still push an H3 buffer back with a can on it (if you use the LMT enhanced carrier).

I am going to mess around with some smaller GP's to see if I can get it down to an H.

It's cool that your doing all this R&D work so the rest of us don't have to. I think I may get something like this when I get an Ops Inc 14th model. Which brings up my question: Will the reflex type suppressor like the Ops give different results?

[Tspeis]

Because, the items has to be un-finished before they will coat it. Could they blast it and then re-coat it? Possibly, but I do not think that this would be the best way to do this. Also, you would need the inside of the carrier to NOT be chromed.


C4

The way it was put to me by the fine folks at UCT was that they put the part through a vapor degreasing and different acids to clean and completely strip it of any finishes previously applied. Sending phosphated carriers should be no problem. Agree with you on the chrome issue, however.

Any suppressor with a large internal volume especially prior to the first/blast baffle will have different results, as they have much lower backpressure.

just got back from the range,

gun specs
DD hammer forged barrel cut down to 10.5 with carbine size gas port
Surefire MB556k
Surefire FA556212 can
factory spring
9mm buffer (i forgot the H buffer and carbine buffer i was going to bring)


Started shooting with no can, Gun would not lock back or load next round, a carbine or H buffer may have helped but i forgot them on my work bench and the gun normally runs a 9mm buffer.

With can gun ran great, less blowback, less recoil, ran cleaner, and locked back on empties.

this was for sure a fun project and glad i did it. Thanks Grant for sharing the info.



a test i plan on running next time out.
running 100rds through my other 10.5 gun with a new FDE P mag, and 100 with this upper and another new FDE P mag, to show the difference in blow back....my mags came out way cleaner with this config. Normally a FDE P mag comes out black around the top from so much crap being throw back.
