FCD - Suppressor Muzzle Device Install - 6315KM

[@jpdesimone]

The most critically important thing I've learned from years of watching your videos is to use the right tools. I've purchased so many on-off, infrequent-use tools that I've seen you use which make these jobs so much easier, safer, and less possibility of damaging your parts. The thickness of wrenches for muzzle devices has been a real bitch to deal with forever. Problem solved by Forward Controls, it appears. Heading to their website right now to make a purchase. Thanks for this video!

I have the FCD wrench but I've also used a bench grinder and ground wrenches down before. Works just fine, deburr it though.

[@williamm.7433]

The best installation of a dead air MD I've seen. Thanks!

[@Big-Rig-Energy]

These videos have been very helpful with my first AR build. Pointed me in the direction of the tools needed to do the job right and fcd products.

[@jpdesimone]

These are finally back in stock. Mine shipped the same day of the order and arrived two days later. Super impressed with the level of effort there, but also the quality of the wrench at first blush. Brilliant idea here. Thanks again for sharing this, #nsz85.

There's a way to do this with math, for what it's worth. If the barrel has 1/2 x 28, that is 28 threads pre inch. That means one full rotation will move the break 1/28" or about .0357" (which is 0.907mm since the shim kit is in mm). You can then just divide by how much of a rotation you are off. Example: try the brake with no shims: if you are off by 1/3 of a rotation, you'll need about 0.3mm worth of shims (or 0.6 if you need to go the other way). It gives you a decent starting point. If between sizes, you round up, cause you can always squeeze them down a bit.

[@nsz85]

This is awesome and makes me wish I was better at math 😂

[@simply_based]

I was thinking exactly this while watching

[@rshinn8776]

I did this to machine my own custom shim

[@jasongaudreau2075]

Great video! I went with forward controls designs (in collaboration with Revival Defense!) 6315rf which is a shortened (1.74” overall) a2 birdcage style (man does FCD LOVE that a2 birdcage, and I do too!!!) suppressor qd mounting muzzle device for q/rearden mounts! It’s freaking perfect for me as I use a eccomachine adaptor on my otter creek labs polonium k. That eccomachine has a 1/4” flange thickness. The direct thread adaptor that came with the suppressor has a 1/2” flange (and no muzzle device obviously) but with the fcd/rd6315rf…..I get about 1/4” shoulder from muzzle device, and 1/4” flange thickness, which means that I only added 1/4” overall length when adding a suppressor. Being only 4.8” overall (without adapter) when adding eccomachine adapter on 6315rf= 4” overall added to barrel length. Mine is 12.5” and ends up 16” flat mounted can. Now a 16” fiddle doesn’t count muzzle device and the standard a2 birdcage is 1&7/8” long. My suppressed 12.5” is 16” total while a 16” is actually 17.875”! Winning the ballistics/cqb war!!! I’d love this setup on a 13.7” fn cl/chf barrel build!

If you tighten muzzle devices on reaction rods, there is a chance of causing misalignment and other issues with run-out on your barrel extension. Mount the barrel directly in a vice with some soft jaws. Make sure you don't tighten down more than 20 ft lbs. The best way to turn a 1 MOA barrel into a 6 MOA barrel is tightening the muzzle device too much. P.S. That's a really nice CMT mlok rail. I have 2 HDM rails. 😉

Can't wait to see the build finished!

[@UnforgivingDemon]

What torque settings did you torque the muzzle device at?

[@JimYeats]

Timing muzzle devices is always a minor PITA. Having the right equipment does wonders though. Rocksett is definitely my go thread locker for anything that gets hot. Holds better, yet is easier to remove - if needed - than stuff such as red loctite.

[@hellraiserrec19]

Honestly if you torque it down to 20-25lbs you dont need the rockset. Helps if you ever want to change out muzzle devices. Rockset is a pita to remove

[@JimYeats]

@@hellraiserrec19 Not in my experience, at least using a suppressor host. A muzzle device at just 20-25ft lbs that is super hot that you are trying to get a suppressor off of has almost always loosened on me when there is no Rocksett or some other compound. Rocksett is way easier to remove than a red thread locker, again, in my experience.

[@silvergrizzly316]

Awesome set of videos!!! 👍👍

[@bangkokinc.4233]

You don’t have to torque it in?

[@floridaman9026]

Doesn't that muzzle device need to be torqued to 20-30 ft. Lbs.? That looked like it was just barely a little over hand tight.

[@jpdesimone]

The Forward Controls joint muzzle device wrench is out of stock everywhere I've looked. Any hidden gem, little online retailers you know of who have it in stock, nsz85? Or if the FCD guys might've let you know when they expect to be selling it again? Any info would be helpful. Thanks!

[@nsz85]

I personally sign up for notifications/emails for everything FCD. They are sometimes hard to come by but always worth the patience.

[@jpdesimone]

@@nsz85 Thanks. I did that yesterday so I'll just wait to hear back from them.

[@BrFishWPB]

How much longer of a barrel do you need than the handguard for clearance?

[@AWZ1287]

Would that wrench work with surefire muzzle devices?

[@Indefatigable222]

Why companies don't make black shims I have no idea.

[@Plumber576]

Check out Accu-washers from Precision Armament.

[@brorx4475]

They do, got some us made black washers on Amazon with smaller outside diameter. I don’t like the washers that are bigger than the barrel.

[@christurbo951]

I just ordered one of these.

[@InkwellFoto]

If your muzzle device doesn't need to be timed, do you need shims? All my muzzle devices are flash hinders from OSS and don't require timing, haven't installed yet cause cans are still in jail

[@nsz85]

The most important thing is that it is lined up to prevent baffle strikes. Sometimes shims can assist with that. YMMV.

[@brorx4475]

No shims should be better, you should still get an alignment rod but shims could possibly make it worse.

[@blackhammer_928]

You don't need shims

[@wassermelones4656]

do you still have that sgl from the tapco g2 installation video?

[@nsz85]

Sure do!

[@DrCap24]

What’s your thought on this device vs the solgw nox?

[@Drain09]

@nsz85 what’s the torque setting at?

[@nicg9599]

Mine was a pain in the ass to time. I used a Dead Air shim kit

[@shawn78789]

Was that Rocksett 15014 or 15015 or does it make a difference? Also,would Permatex 80078 do a well?

[@nsz85]

[@KaneGregory]

Will that make a rifle that’s 14.5 or 13.9 a 16?🧠🤯🔫

[@cory7328]

Dude you have just dropped a ton of videos in the last few days.

[@crypticplayzzz271]

Thank you!!!

[@Reisito305]

Is this the same as the SOLGW nox?

[@nsz85]

No that is a different muzzle device but with the same supressor attachment which is Dead Air.

[@timowens7214]

I don't time my muzzles unless it's a brake because they don't get ran without a can 🤷
