SPR style suppressor

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.

SPR style suppressor

Post by BCJ »

Just finished this one for my 16" AR that has a SPR contoured barrel. I used the Spikes SPR brake mount and an Allen Engineering collar. The suppressor is all 304 Stainless steel. This one is the same dimensions as the Ops Inc/ Allen suppressor. I used 8 machines cones inside. My 14th form 1 suppressor, using a Grizzly 10x22 lathe

Nice.

I'm waiting on a stamp to do almost the same thing, just on an 18" bbl.
I'm planning to make the rear mount integral to the gas block and the muzzle device will be of my own design.
Care to share your baffle spacing?

Results?

ETA:
Where are the mounting threads? I don't see the Spike's SPR brake as having any and the Allen Collar is just a taper mount, for aligning and tensioning.

Think the shady portion at the rear of the brake is the threads

Hmm. I didn't see that one on their website and when I zoomed into BCJ's pic, I didn't see threads. Makes sense.
