I have the following silencers:
RPB Industries model M11 , 11.75” x 1.75” with 380 mac threads, straight solid body
Miltary Armament Corporation model M11, 8.75” x 1.75” with 380 mac threads , 2 piece but straight body
Values?
Which one am i less ruining by recoring to modern standards?
I tend to think that the longer rpb can may turn out to be a better performing 380/9mm subgun can. I am also guessing the M.A.C. can is probably more collectible/valuable…..
How wrong or right am i?
Thanks in advance

Could you post pictures of the RPB suppressor in question? The RPB manufactured M11 .380 suppressors were the same exact design as the MAC mfg M11 .380 suppressors, same dimensions, same internals, same 2 stage 2 piece design. What you are describing, longer length, 1 piece construction, doesn’t jive with any RPB manufactured M11 380 suppressor I’ve ever seen.

Regardless, the MAC manufactured suppressor is more valuable as a collectors item than an RPB. Despite the RPB m11 suppressor being the exact same design as the MAC, the original MAC stuff is more collectible.

Here is some info on the MAC/RPB M11 suppressor and a picture of the RPB M11 .380 suppressor. It should be the same exact dimensions as the MAC suppressor and the same design/construction. The only difference would be the finish and the markings on the first stage “RPB INDUSTRIES INC”

These are not my pics

I tried reducing my picture to as small as possible and the crap uploader still won’t allow it. I sent a pic to a guy that recores them and he said it was a rpb 9mm can. Even though it is threaded and papered as 380. It doesn’t have that 2 piece look to it.

I honestly don’t know of any single stage RPB manufactured m10 or M11 suppressors. I sent a PM. Thanks!


ETA: here is the suppressor in question. It is a rare and unusual piece… this is a very early RPB suppressor, one of their own unique design. The first iteration of RPB (75-76 I believe) made some suppressors of their own design before being purchased by Wayne Daniel in 1977, when they resumed production of the standard SIONICS style MAC suppressors.

It is the bottom suppressor, long as hell for a 380! Something tells me RPB was using the same size tube and design for both M10 and M11 for these suppressors. No caliber markings on the tube. Marked:

RPB INDUSTRIES INC
ATLANTA GA USA
R 16

Unique horizontal RPB rollmark , very early SN. The R prefix remained into the production of the typical MAC style 2 stage M11 suppressors, most of which are in the 3 digits, making this likely one of the earliest RPB production suppressors.

Unique encapsulator nut design. Utilizes a flat head to remove, unlike the standard MAC encapsulator that required the proprietary encapsulator wrench with the 2 pegs.

Thanks for sharing this unique suppressor! A very cool piece of history!

Just a thought, with possible legislation around silencers, would you be better off waiting? What exactly is going to happen with cans makes me wonder about what restrictions look like in the future. It is my understanding that under current law, if you have an original Mac style can, the Manufacturer would not take your can’s specific internals and bundle them together so in the future, if you wanted to return the can to original configuration, you couldn’t. The SOT won’t be storing them. So those internals would become scrap.

There are several possibilities for silencers. The best option considered is that silencers are treated like Title I firearms. As with Title I firearms, I would think that you could own extra parts. If so, you could store your original internals. Then if you chose to, you could put the original internals back in it. There is an element of history to these cans. Market values have climbed. Every recored suppressor is on less one out there.

I also have to ask, how much more would it cost to have a completely new can made instead of being recored? I don’t know. I am asking.

Definitely repack the RPB can. Leave the MAC can as original. Some of the very early RPB cans had packing type internals.

A recore is about $350 with a lifetime warranty.

I wouldn’t recore any of them. Especially, the iconic two stage MAC can.

If you want to sell the MAC can, post it on here, you’d probably have a buyer fairly fast. The RPB (longer) can, might be rare but I personally wouldn’t buy it. It just looks too long. Especially, for the small M11 and doesn’t have that cool OG look (imo).

I think we have figured out that this can is not getting molested. It will live out its life in someone’s collection

Definitely the best choice here. There are plenty of suppressors on the market that make excellent shooters, no reason to butcher a piece of history, especially such a rare one. Normally an RPB suppressor wouldn’t be anything of any real collectible significance, but this one is, and I’m glad we were able to identify it for you and that you have made the right choice to keep it as it was originally manufactured and pass it on to a collector who will appreciate its place in Ingram history.
