SILENCER SATURDAY # 255: Prairie Tactical PTAC-30S Serviceable Rifle Suppressor

Good afternoon everyone and welcome back to TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the YHM Turbo T3 rile suppressor. Last week we had an in depth conversation with Karl Brügger from B&T. Thank you Austin. This week we take a look at the Prairie Tactical PTAC-30L fully-serviceable .30 caliber rifle suppressors. How does it rank against other options on the market? Let’s take a look.

One of the biggest debates in the history of silencers revolves around centerfire rifle models and whether or not they need to be user serviceable and cleaned on a regular basis. The majority of shooters probably wind up on the side of ‘no cleaning necessary’ while a vocal minority requires regular cleaning to prevent fouling. So who is right?

Nobody. Or everybody, if you want to sound more positive.

For those shooters who shoot high velocity ammo at semiautomatic or rapid fire rates, rifle suppressors will most likely never need disassembly (if possible) or any manual cleaning. Shooters who mainly shoot subsonic ammunition at slow fire rates may start to see a buildup of fouling after 500-1,000 rounds and could probably benefit from some type of cleaning. But soaking in a safe solvent, draining, and shooting high velocity rounds usually does the trick.

As a caveat, some specialized rifle suppressors, like those made using additive manufacturing techniques, may require more frequent cleaning to avoid debris filling in the narrow gas pathways. The HUXWRX Flow 556K 5.56mm recommends cleaning every 500 rounds. And rimfire suppressors should definitely be cleaned regularly.

As a reminder, it is up to you, the consumer, to decide what is important for your needs and buy products that perform those task as best as possible.

The PTAC-30 line of suppressors use a 1.5” diameter tube which is a solid balance of strength, weight and internal volume.

The front cap unscrews using an included wave style wrench.

The last baffle in the stack is shorter than the rest, with a sidewall height that is about 0.25”.

The rest of the baffles in the stack have a side wall height of about 0.60”. Note the deep cut “mouse hole” vent and the notches in the side wall that allow the stack to be indexed.

The notches come together to keep the stack aligned. I kept the mouse holes all on the same side, but it would be interesting to see if alternating sides improved performance in any way.

Two weeks ago we discussed the 1.375 x 24 universal mount standard that has been adopted by many suppressor manufacturers. The one downside of a 1.5” diameter tube is that it doesn’t leave enough room for 1.375” threads. However, the PTAC-30 system does use the same thread pitch as the SilencerCo Alpha line of mount adapters. This opens up the ability to use three lug mounts, and some flash hiders and muzzle brake systems. Prairie Tactical does offer a PTUM QD mount system and they are working on a 1.375 x 24 universal mount adapter.

This is a well made suppressor that is machined to precise standards. The baffle stack slides out easily, the threading is smooth and refined, and the Cerakote finish is clean and even. None of that may not effect performance, but it is indicative of a company that cares about important details.
