So in MD we are now allowed to buy lowers again, our choices however are slim HBAR, Pistol, or SBR. So naturally I am gonna build an SBR I pretty much already have everything on order except the Handguard and of course the barrel. I plan to use a 10.5 Noveske CQB (suppressed). I really love my BCM KMR and key mod in general but feel a quad rail looks better on an SBR.
Give me some thoughts, I would prefer something 10".
Thanks
Centurion C4, DD RIS II MK18… It’s not a full quad rail, but the Centurion CMR 9.5 is really nice, too.
Have you seen the MK18 in stock anywhere ?
Rainier had them a few days ago, in black and fde.
ETA: Still do.
Very nice Zim thank you,
The DD Lite 10" is more me I think for that coin.
You might run into clearance issues with a 10.5" barrel and a true 10" rail.
I wasn’t sure of this, do you recommend a 9.5+?

You will have clearance issues with a 10" rail on a 10.5" barrel.
ETA: Zim beat me to it. 9.5 max. Not a quad but Geissele makes 9.5’s too.
Good stuff so 9 or 9.5?

The Mk18 comes in at 9.55, and the CMR is 9.44. You need the wrench flats to be forward of the end of the rail for a can to mount, basically. It’s personal preference between 9 or 9.5, but I prefer the 9.5ish rails.
I’d go 9.5 if possible but That’s up to you. What are you looking for in rail specifically? I think you need to determine that first, that way we can narrow down your choices.
So let me ask you this. I order the spec war 5.56 with the trifecta mount. it screws right on and does not go past the muzzle device. Am I ok with a 10" piece?
I have no hands-on experience with that suppressor+mount but the problem with a 10" rail over a 10.5 is that the rail extends past a portion of the threads. On an A2 FH, it’ll actually cover the wrench flats.
Check out the fifth picture at Bravo Company. That looks really tight, and might depend on the ID of the rail.
Yessir I see your point of concern, but as far as I know this system locks up tight and does not have any hangover what so ever.
The problem is that it can’t lock up tight if part of the threads are covered by the rail, unless the internal diameter of the rail is greater than the external diameter of the suppressor. The suppressor will run right into the end of the rail, and fail to thread all the way onto the barrel. The C3 is 1.37" ID, while the SpecWar 5.56 is 1.5", for example.

^uh oh…
Thank you guys for all the input, I appreciate it.‘’ Now if you will educate me even further. I have a 10.5" BBL, a 10" rail system, a trifecta muzzle device that extrudes past the 10.5", but the SD it self locks down prior to going past the end of the MD(muzzle device ) like so …
Alright this is where I stand.
I need to decided on a rail.
