SP10 suppressor

[UKMan]

Getting tired of looking/watching videos..the rabbit hole is real. Seekins SP10 6.5cm will be arriving hopefully soon (Going on 7 months at the moment).

Looking for maximum sound suppression and direct thread. What do people have experience with/recommend? My bolt gun .30 suppressor does a wonderful job but has an upper heat limit of around 500 degrees…I am not mag dumping but would prefer not to worry about it on the SP10.

What I have on the radar:

Lower end of Budget
-Otter creek Polunium 30

Top end of Budget
-Otter creek Infinity
-Griffin DUAL-LOK PSR 7 7.62MM
-Thunderbeast Ultra 9 Gen 2

I keep reading great things about the Polonium 30 for the price (besides being gassy). Other options are 2x the cost but I don’t mind spending the money if it’s worth it.

Any help to help me stop the search would be appreciated!

I am using a rugged Radiant on my SP-10. I am using QD muzzle break, but I think it can direct thread also. The Synthe TI from Silencerco is also a great performer.

I wouldn't put a TBAC Ultra on a semi-auto.

Get a low back pressure flow through design. Easy button on semi autos which won’t be as quiet as a bolt gun anyways. You can put it on and take it off and not worry about adjusting gas.

Take a look at the B&T that has a free tax stamp on it now too. I have one and it works great.

I wouldn't put a TBAC Ultra on a semi-auto.

Why? I use a TBAC ultra 9 on my ar15’s and ar10’s. Zero issues. I’m not mag dumping on the 10’s but do occasionally on the 15’s.

From TBAC website:
"Material Properties
The Ultras were designed to be the "ultimate" lightweight precision rifle suppressor. This means we used materials to meet those goals. Titanium, even Grade 5, is ultimately limited by temperature. The Ultras are very strong but excursions above 800 degrees are not good for the material. If you take it far enough above 1000 degrees, it will get too weak to sustain the blast and you would eventually get a failure. We recommend keeping the Ultra series less than 800 degrees.

Full auto by itself does not really increase the pressure or stress on the can, it's the heat energy input in combination. Full auto or bursts would be fine on an Ultra as long as the material temperature does not exceed that 800 degree safety mark. In our testing, one magazine fired rapid (mag-dump) from from an AR-10 or AR-15 does not exceed 800 degrees. Keep in mind this is firing at a full-auto-like rate. At that point you'd just have to let it cool. The second magazine may or may not cause it to exceed it depending on ambient conditions, loads, barrel length, etc. A shorter barrel will cause more heat input into the suppressor and its temperature will rise faster."

Just a bad fit for this firearm.

Why not pick something designed to handle rapid fire and not need long cool down periods?

I have two Ultras, a 7 and a 9. Great cans, but I run mine on precision bolt guns.

I too would go low backpressure. With .300 blk subs my higher backpressure traditional baffle cans are fine. But with supers I prefer the lower backpressure options now.

The experience for the shooter is more pleasant (less port pop), the guns run better (at least mine do), guns don’t get nasty as quickly in terms of receiver crud, and the only real downside is slightly more noise for bystanders. It’s all compromises and I guess that’s where I’ve landed now.

Silencerco Velos 762 with Recoilx brake. Great suppression, low back pressure and excellent recoil reduction.

I have a PTR Vent 1 that's fantastic so far. The next can(s) on my list are Ridgeback Defense Sahara 762 or 300. Looks VERY promising at a nice price point.

My CAT JL is extremely quiet but haven’t yet tried it on a gas gun. Their website says it was designed around a 20” m110 so should be great on an sp10.
You’ve already got the infinity on the list which would be a great choice too. The FOR systems Monarch 762 also seems to perform really well. All of these options are lower backpressure and available in inconel or Ti.
I’ve found on precision guns (like an sp10) I haven’t felt like I needed an inconel can.
