Re: Scope question

Being a silencer forum it seems an odd place to look for scope advice. Here's a thread from 2015 with a similar question involving the two brands you're referencing, if not the exact models: https://www.ar15.com/forums/ar-15/Monstrum_or_Vokul/18-680889/ I concur with the prevailing opinion there, in...

Re: Suppressor on Ruger PC9 Carbine?

Probably a decent choice, but I'm likely to stick with what's readily available. No Fiocchi 9mm showing up in any retailers to which I have access, though they seem to have that brand in .357 and .45. The Remington UMC cycles well, is reasonable on the ears, pokes holes close together on target, so ...

Re: Suppressor on Ruger PC9 Carbine?

Thanks a lot for your insights. I'll not waste my time and risk damaging something with that little project. In the case of the TNW Aero, perhaps the more significant bolt carrier weight and the chunk of steel they put into the front of the spring is enough to keep port noise lower than those other ...

Re: Suppressor on Ruger PC9 Carbine?

Hi ECCO. Sounds like you've tested holding the bolt closed, if you're saying it hurts. So I'm wondering if you have a guess as to how much metal might be needed to assure reliable, durable bolt restraint, as an add-on for a 9mm PCC. Have a different model of 9mm takedown carbine and more specificall...

Re: MP5 SD suppressor design - Blast chamber

If you're talking about vent holes going back into a reflex volume, a portion of the can extending back over the barrel, then one advantage is a reduction in pressure on your blast baffle and to the baffle stack overall. Maybe not a massive difference but something. And suppressor efficiency is larg...

Re: Coatings to support cleaning

White lithium grease on the first couple of baffles helps a lot, remains useful towards ease of cleaning for a few magazines' worth of .22lr anyway. Some people have baked baffles in a tin of mineral oil and reported success - there's a specific procedure outlined for cleaning and soaking somewhere....

Is there a good rule of thumb for calculating how much space there needs to be in the baffle section? Right now, cone trimmed, I am looking at 3ish inches.

Anything above about 10fpe and felt wraps and hair curlers start coming apart.

Re: 458 Socom - Lets Talk!

Add to that ECCO's fairly strongly stated sentiment that reflex volumes mean next to nothing in terms of suppression efficiency, and yeah, seems like all that weight is a bit excessive. I'd suggest keeping your design if ruggedness in terms of dropping/bashing the rifle is a concern, but switching t...

Planning on using 1.75 OD x 0.65 Wall 316 SS tubing. Just noting your type, because hey, little errors can become painfully big errors because of typos. If you use stainless tubing with a wall thickness of 0.65" it's going to weigh about 5 pounds. Probably better going with 0.065" wall. But you kno...

Huh, hadn't seen that modification to a conical baffle before. Seems they've borrowed the central jet/vent feature from a K baffle and incorporated it into a cone baffle. Cool. I can't see it working quite so well on a rimfire round as a proper short K baffle, but it probably comes close. If you wer...

Re: New guy with a bunch of questions

1. Probably legal, but why risk having to get a lawyer and defend yourself? Why not wait to have the documentation in hand before you start making baffles, or order a 'solvent trap' sort of kit? Waiting would seem prudent. 2. I've seen a lot of folks do the engraving after doing everything else exce...

Re: Creative way to drill pin wrench holes in an endcap???

What about this to get spacing even? Scribe a line through the punched centre hole in the tool piece before drilling it. Drill three small holes with a centre drill so there's no wandering, each one along the scribed line. Drill your centre hole in the tool piece and cap to spec. Mark one of the two...

Unlikely to be as quiet as a properly designed dedicated .22lr can, but it should make the smaller round hearing safe.

You could spin up the lathe and use a cutoff wheel in a Dremel to grind through the hardened layer. Not fun, makes a lot of dust, but those little fiber cutoff wheels are cheap and a few minutes of grinding should get you through.

Re: porting barrel

The more relevant problem is spacing of the ports relative to the chamber. Generally for keeping lower powered stuff subsonic it seems most go to around 4" for rimfire, sometimes closer. Some of the integrally suppressed Rugers get cut down to just 2" or 2.5", such that even high velocity stuff come...
