kieran1141

rang the guy that threads my guns today and he informed me that i could not interchange a ase utra northstar n3 from my 243 to 308 as my mod up to 25.06 max, told me to bring it down and he will drill it 1 1/2mm wider as he has done this for a few lads and it will go on the 243 as well, thread stays the same, would loose about 2 or 3 db's but would not no the differance, said .25 and .30 same mod onely .30, 1 1/2 mm wider. saves on another mod.

In theory it might not sound too bad, but i'd say its not one of the manufacturer's recommendations...
loosing 2 or 3 db could be the least of your worries:eek:

tuukka, he pops up on a few forums and works for ASE so should be able to answer your question, i've heard of it done before but i don't know if i'd do it with out hearing more

Just wondering, currently with over 30yrs service I never knew any gunsmiths only armourers in the DF's

Yes can be done, by a competent gunsmith
Put mod in Lathe and bore out 7.9mm
Will be a shade louder, but not much.

I use a .30 cal mod on .308 and .223 for the record

I personally would have a chat with the likes of tuukka!!

Having a .308 mod on a .243 is one thing but machining a mod to open it up to suit a larger caliber is a different story

I could be wrong but you are weakening the mod and due to the gasses that are expelled from firing the rifle the now altered "silencer" may not be able to hold the pressure and could possibly fail, your talking about thousands of an inch with firearms and the suitablility of materials for firarms

That is just my thinking

If i were you i would sell the existing mod and buy one that is suited to the .308 cal or buy the likes of a willdcat predator with a .243 baffle and .308 baffle

I'm using a 30cal ASE Northstar on both the 223 and 308 without any problems.

I'd say drill it out it's not even a couple of mil in difference.

Moderators can be drilled out but it depends on there baffle design. Most commercal suppressors are simple so there wouldnt be a problem.

you will have to excuse my ignorance, but he calls himself a weapon technician he says or armourer, and works at gunsmithing.

thanks clivej, we'll give it a shot lol....

Gunhappy is right. My take would be, if the manufacturer of the mod has
the same design in a larger cal and the baffle shape allows boring out, then go for it.
Important is to have evrything centric. 308 needs at least 8.5mm diameter hole.
I know that some A-tecs with 8.4mm can be finicky.
My 308 mod has a 10mm hole, no worries with accuracy.
