Edit:  going with the SLR, however this has become a cool shorty thread!

Now taking recommendations for this setup. It will be suppressed, but haven’t yet decided what can.

8” Geissele .300 on a BRC upper and RCA carrier.

I have a 10” ALG EMR V2 available to me but don’t think this is the ticket. ALG made 8” keymods that I see for sale occasionally. (Not looking anymore)

I might put a light on it but that’s it, so don’t need much “rail estate.”

Also looking at some of the MI units.

I switched all mine to the Midwest Industries SP series. Figure the fatter suppressor style keeps the handguard further away from the barrel and gasblock to keep things cooler than the super tight to barrel handguards.

SLR rails are my favorite, but they are expensive.  

The KAK 7.2" rail is nice and solid.  No QD though... but that isn't the deciding factor for me.  

I also like my BCM KMR (MCMR) and Griffin Rigid Rail for a slimmer setup and feel.

I have all MI combat rails, including a 10.5" rail on a 10.5" barrel and an 8" rail on an 8" barrel.  But I don't have suppressors to deal with.   I do have Breek Arms muzzled devices with external threads, and that combo is about perfect with the flash cans that are available.

I have a 300BLK with that handguard. iirc requires a proprietary barrel nut tool to remove. I bought the ALG  tool back in the day but never used it and just kept the ALG keymod. The ALG tool happens to be purple.

Lately I'm back on the "swap it out " bus.

The kak 7.2" would be good. You can also chop a 10.5" Geissele MK16 to about 7-1/4" to 7-1/2". Can't remember exactly right now.

Thanks, looking at options. I do have the purple wrench as I have a V2 on a “light” slickside billet upper with a BRT barrel and tube.

I really like the MI Combat Rails (have an MI folder on a 10/22 chassis and an MI on a .308 AR). However after looking at cans and can diameters, I think this SLR fits the bill. Project will take a couple months, I’ll post pics when done:

would a 6" handguard be a viable option?

Well, the barrel is 8”. I have yet to measure how much is forward of the receiver, but this seems like 6” would cover the gas tube but not much else.

Thinking about a fat can of some type since I have an Aimpoint T1 pretty much permanently attached with JB Weld to a high Unity mount. (Don’t do this at home. Mount screw issue.)

The Aero Enhanced is probably my favorite if you can still find them
https://www.aeroprecisionusa.com/ar15-enhanced-mlok-handguards

The 9" version would tuck just a tiny bit of the can or maybe just the mount, the 7" should clear everythting

Here's my faux-integral setup with a 10" barrel / 7" can / 12" handguard



My 2nd favorite that's pretty light is just a basic magpul carbine setup



Both will only fit a can that's up to around 1.65" outer diameter though

Thank you. Those are good looking rifles. Is one a BRN-180?

While I think the Tisha or Dead Air OTBs look sweet, one would need a shorter HG and the other, I don’t have guaranteed 3” of clearance between gas block and threads… it will probably be an older Nomad with the SLR. Just got the lower together, mostly. Grip is a placeholder.

Because of the angled bolt stop cut in the upper, the Radian bolt stop fits like it was made for it.Attached File

I run a BCM Quad rail on my 8".  Almost a perfect fit.   Here is a pic showing barrel/plan b/ suppressor interface.

I'm using a Samson Evo 7.6" on a 8.5" barrel, it will work on an 8" just as well. I really like how slim and light it is and the Evo mounting system keeps things well streamlined.

Yep, with a Lingle BAR handguard adapter

For the Nomad, there's several vendors making muzzle devices and/or mounts are recessed to shave off some length and tuck the narrow part of the can under a handguard

Comstock has a infographic about theirs and Rearden, Wolfpack, and maybe DDC and LPA also make similar

.45ACP with 7.5" barrel. Unsure of handguard mfg.



.300 suppressed with 7.5" barrel. I believe these are IMI handguards

@SSG-69 this should help.

Here’s my 8 inch build with the same SLR rail.

Sweet! Conceptually similar.

I can't remember if this is a 7.5" barrel or an 8.0" barrel, I have both, but this is a carbine-length free float quad rail so just over 7"
