- 223 moderator silencer
Interesting maths behind that physics. 0.256-0.224=0.032 divide that by 2 for radial clearance and you get 0.016" which is 0.406mm.
Worked another way 6.5mm minus 0.94mm = 5.56mm.
How thick is a bawhair and how loud do you want your BANG?
Happy to be corrected on this
Are the ase cqbs over barrel? If yes, can someone kind please measure the diameter of barrel that it would accept? TIA
I know that a .223 bullet fits through a 6.5mm mod, in fact I've used one on my .223 Rem.
I also know that .30 cal DPT mods are really efficient on .308 rifles because that's what I use on mine and I would happily recommend them and I'm in the process of buying another.
What I'm saying is that the maths behind the physics using your figures does not add up to a radial clearance of either 0.47mm or 185 thou of an inch and I notice that you have not addressed that point. You were initially talking about .20 cal baffles and not those in a 6.5mm mod, which will be a tad bigger than 6.5mm.

Just ordered a Stalon X108 from @R. Macleod & Son
had it in stock and great price.
Looked at reviews and seems the X108 is hard to beat when priority is weight, size and moderation are my priorities.

Yes my figures are out. I also missed a decimal point as it's 18.5 thou not 185 and you are correct the radial clearance is .4mm or 16 thou not 18.5 thou
A 6.5 mod has a 7.7mm hole/bore, thats not a tad bigger thats an enormity and yes a 5.56mm bullet will 'fit' through a 7.7mm hole.
I was talking about a 20cal mod. Which has a 6.5mm hole through the middle.
If you measure the hole/bore of your DPT 30cal mod, you will find it has a 8.89mm hole (0.35").
The .308 bullet is 7.82mm in diameter, which equates to a sh1t load of clearance ....
My point was that if you have a large chamber and a close fitting bore the moderator will provide more suppression than a moderator wth a similar voume and a larger hole/bore.
In your case a DPT 7mm baffle stack will be a tad quieter than the 30cal baffle stack you currently use, and the bullet will fit through it as the bore is approx 0.7mm smaller which is still 0.4mm larger than the .308 bullet.
If you could cool you moderator it would provide more suppression too, maybe thats the next gen, finned mods ?
@Miki Thanks for checking and addressing my query of the figures. I understand the physics and agree with all the points that you have made about reducing the radial clearance to a safe working minimum in order to achieve the best sound suppression. I can also guess a number of reasons why manufacturers produce baffles for given calibres with greater clearances.
I’m all honesty doesn’t it really matter. I know some one on here who has chased ultimate suppression and paid a hell of a lot of money doing so. They now run an Ase Utra CQB for convenience. Any silencer is such an asset over nothing and the real world difference between the suppression capabilities of any on the market now days are nearly indistinguishable to the human ear and there will always be the perceptional awareness of the witness that influences any opinion.
Although these internet discussions are great and keep me entertained whilst hold up unable to get out and shoot.
The problem might be that when they change models, new baffles are no longer available for the old model.
As a Stalon fan I have the 145 on my 270 and rate it highly, I handled the Victor at a show it’s lighter and slimmer can’t speak for the sound reduction

I have a Stalon Xe149 on my .270 which I really like, but I have a ASE JetZ CQB .223 rated moderator on my .222 which I rate as pretty much the perfect foxing moderator.
Excellent sound reduction, nice and compact. Not the lightest but my .222 has a heavy barrel anyway and 99% of my foxing shooting is off the bipod.
Brilliant service from Jackson Rifles if you have any old Atec or ASE moderators that you can trade in.

Hadn't heard that! I have some 7mm Mk1 baffles and ordered a new 7mm moderator. A Mk2 turned up, so I'm going to use the old Mk1 7mm baffles on the 223 Mk1, now that the 223 baffles are almost cut enough to take a 308 bullet. Tempted to get a full set of stainless baffles next time!Aye, DPT tried that, everyone kicked up stink, sales went through the floor, 44.5mm baffles, bridges and vertex chambers available again ....

I've a wildcat Evo on my .223. Cant complain about the mod. A bit sh!t they dont ship parts anymore but other than that, its pretty good
