Form 1 Reflex Build

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Why did you go w a pair of 180* oriented notches instead of the (3) @ 120* offset? They offer both asymmetrical and quasi-symmetrical cross-bore turbulence.

Also, how do you prevent the baffles from sliding forward using the shorter muzzlebrake? Do you use a spacer? Or just allow the pressure to force them forward during firing?
Thanks!

I had previous experience with the dual clips and knew they worked. Also I am without much tool wise, and the dual clips can be aligned and cut by eyeball with a dremel disc drum.

I cut out the spacers in this build, the baffles lock in place pretty good after shooting a mag through it. I will follow up on this long term, only 300rds or so so far (308, 300blk, and 5.56)

Not tested yet, but the same basic concept 1.5" shorter with a bore suitable for 5.56. The 308 has been a dream to shoot, so much so it hard to shoot other setups for me now. Wish I could have some purchases and builds to do over again.

1.625" solvent trap, with steel ends and internals, 16.1oz, 7" tube body, 7.6" overall. Mounted on my Compass Lake 12.5", comes back to the (carbine) gas block, clears the block by about a 1/4". Shorter overall than a 16" build. Suppressor on the reflex mount extends about 2.45" longer than a FH or Flash Comp without a can mounted.

5.56 Range Test
12.5" SBR with Reflex mount
12.5" SBR with 5.56 DM Form 1 (adds about 2.45")
12.5" SBR with 30cal DM Form 1 (adds about 3.90")
16" with 9" 30cal can

As mentioned before I had some concerns the 5.56 Form 1 would be too short, bc the shorter OPS cans are quite loud, but it turned out well. The 30cal one (about 8.8") sounded awesome on all platforms so I rolled the 7" DM Solvent Trap (came out to about 7.5-7.6" OAL) into a 5.56 reflex instead of a standard can. They can both run on the reflex mounts, or the standard QD Griffin mounts.

c5_nc, I have mailed my Form 1 for a 8" 30 cal build, and it will be an all Ti build with 1.625" OD tube, reflex design, short press fit spacer on first baffle, hollowed out end cap, and VSR's.

Questions:
1. What length should the spacers be for use with VSR's?
2. Do you recommend the DM Griffin reflex break or the DM Reflex adapter?
3. What gap would you use between end of Griffin reflex break and first baffle?
4. What gap would you use between end of DM Reflex adapter and first baffle?

Your videos were my inspiration,

1. If DM VSRs then .50"
2. Well the QD system is quite nice but more. Kinda depends on your needs.
3. Geez mine is were it happened to land, about .25" or so. Very minimal, as you are cramming baffles into a tight space.
4. I don't have one of these but probably 1" or so.

This can continues to rock, my favorite of the ones I have built. Always get comments on it at matches. Ryan

The QD Mounts are 1"-20unf.... is that what you were asking? Tube ends are 24tpi

I'm not sure if would be any different from any other can. It has been mostly used for 3gun and training for 3 gun, which rarely more than 50-60rds before the stage is reset.

Might have missed this but how are you keeping everything tight in the can?

Is it just on big spacer with a blast baffle? Or does the stack rest up against the end of the reflex break?

You could use a blast baffle spacer, but the cones are tight to the walls so I did not use one, they stay in place and can be pressed out for cleaning if needed. You can do this in front of of them but not behind them.

I want something a bit lighter, so Ti intenrals and ends this go around. Tube is slightly downsized from before, 1.5"x1.375" at 7", 7.5" OAL. Single clips, coned endcap, and radials this go around. Was aiming for 10oz.

Another fantastic build.
Are you using the same reflex mount from the pic in op?
Did you work up to the clip size/depth or just go for it? Performance?
You should anodize those parts. Some crazy color schemes you could have there.

Its actually configurable between multiple mounts. In the standard configuration it will work with Griffin's standard QD muzzle devices, it will also work with a 1.5" DM reflex mount. The DM reflex mount extends less than 1" past the barrel, so it (in 1.5" or less form) will accommodate most suppressors just built for the brake (like factory Griffin cans), also it is as far back as you can go for a 11.5" with Carbine gas system. The blast chamber spacer and blast baffle can be removed and the can will fit the 2.5" DM reflex mount. The spacer between the bb and second baffle would be a spring spacer or fitted spacer to keep the stack in place. The BC spacer was removed in the two reflex cans I posted before, the cones fit tight to the tube. They are slip fit here so need help. Can looks like it would weigh in about 9.5oz for the 2.5" mount and 11oz for the 1.5" mount. I will wait for a range test, but I am guessing it won't be much of a difference and it will just stay in one configuration.

I oxidized my last Ti tube with oxiclean to a darker gunmetal color. I think I am going to do the same on this one. Leave the baffles bare.
