moderator threading

rowa

hi
i have a ruger 10/22T that i use for informal target shooting and pest control , i have a parker hale silencer ( the old steel ones ) and i want to thread the barrel so i can use it , i have been told though that if i do so the gun is out of proof and must be returned to the uk for proofing again , is this true ? the barrel does have a small proof mark about 3/8ths of an inch from the muzzel and if i thread the barrel this mark will be obliterated.
i have been told that people were challenged to provide a proof cert on ranges such as the one in the midlands .
i don't want to do this and then discover that i can't use the gun on a range or sell it on in years to come , anyone know for certain ?

if you tamper with a barrel by cutting of threading .your firearm is out of proof

rowa

thanks for taking the time to respond jwshooter , i find it difficult to believe that cutting a thread on the muzzel end of a barrel constitutes a risk of failure , especially with a rifle chambered for a rimfire cartridge, still rules is rules and i'll leave it alone or buy a threaded barrel .

Royalred

jw shooter is correct. Any interference with a firearm after it has been proofed, renders it out of proof.

Do you use a Mod yourself Royalred,.

Royalred

Dont use a moderater yet, waiting for permit. Using 6.5. Names not paul, thankyou,

I could be wrong,but Im sure I read somewhere that its not even mandatory in the UK anymore to have a threaded barrel proof tested and its definitely not mandatory over here.The only place you could have trouble is on the ranges.They have some <policy I don't agree with> of no unproofed threaded rifles on the range.

looked into this a little further today , i looked on the website for jackson rifles in scotland who do a lot of rifle rebarreling and custom rifle building , they were apparently in dispute with the proof houses in england who wanted all threaded barrels and the sound moderators too , to be subject to reproofing , as the proof houses are private commercial concerns it all wound up in court ,
from the report of legal counsel :
"the cutting of a screw thread on a barrel in order to affix a sound moderator is most unlikely to reduce it in substance or strength although each case will depend on its own facts"
jackson now advise against the reproofing of a threaded firearm saying it does more harm than good .
also i wonder if a barrel is drilled and tapped for target type scope mounts , does it also have to be reproofed ?

Go and have your rifle threaded if thats what your after.Thers no problem over here with proofing.Its a complete load of crap anyway.

Correct
Midlands I think have a policy if you have a supressor you have to show it was factory threaded or show it as reproofed though I never seen it enforced,but if you are firing at a range without the supressor there is no problem. I am nearly certain you do not need to have it reproofed it is only a money spinning gimmick so just shoot away and enjoy do not worry about it,no-one will put to nor from you over it.

No need for proof here,just get it done by someone competitent.

And what do we do if our firearm is out of proof????

Rowa,

I have some of my rifles threaded, key item is to get someone both competent and professional - I used Mr John Greene of Southern Rifle Optics.

Also take note, that moderators must be licensed by An Garda Síochána, reference - No 12 of 1990 - FIREARMS AND OFFENSIVE WEAPONS ACT 1990 - see section 7.

the process is relatively easy.
apply in letter format to your FO (see other threads on this shooting board for advise of wordings)
you need to justify why you want/need a moderator, XYZ reasons.
there is no cost for permit from AGS.
you must renew permit every year.

hope this helps.

Awh right,so the hundreds if not thousands of guns here without proof are potentially leathal??
Better stamp my Rem before the bolt blows!!!

thanks zulu dawn , i'd be doing the threading myself as i am a qualified turner and have my own lathe to do it and as for the moderator there was one hiding behind a load of junk on the shelf of the gunsafe for years , i asked the local guards was i good to go and all i got was a blank stare , they didn't know .as for the whole proof thing i know after working in engineering for years that the barrel is not going to burst , its the heavy barrel target model and all i use are standard or subsonic rounds the barrel wall thickness has to be in the region of 10mm thick , the gun wouldn't have been originally proofed in the ruger factory in america and the only reason it was is the gun came in through the ruger importers in leeds in england and was proofed there , i just don't want to have a gun i can't use at the range or sell on in the future without spending hundreds on pointlessly .

rowa not telling you what to do, just some suggestions
If you have a heavy barrel then i would cut as large a dia thread as poss,if u have enough meat on mod to bore and re cut,
Or if not,recess crown behind mod thread
Also centre off bore and not barrel if possible,
BTW what lathe do you have?(mild interest in machining)

rowa

i was going to turn up a brass spigot that would be a reasonably tight fit in the bore and use the dial gauge to center the barrel in a four jaw rather than three jaw chuck , the lathe i have is a colchester master 2500 and its good .

Thanks for reply,Have M300 long bed myself
Spigot is good idea,i know it's probably over kill in this situation but spigot on both ends and spider on spindle would be dogs nuts
Good luck with it and let us know how it goes.

I have an old .270 ruger,its a good ould rifle but I often taught about having it proofed,could you just explain that proofing technique of yours a bit more it sound interesting and would certainly beat having to send it across the water.Cheers.

i believe the americans do proof test there firearms but it is not compulsory and they have no proof houses like britain and italy do for example , i did see a documentary on the discovery channel about how ithaca shotguns are made from beginning to end and they are proofed , the procedure was after the gun was assembled and inspected a qualified gunsmith would take the gun out into the yard and place it in a clamp on a small bench , a proof round would be chambered that produces twice or three times the normal operating pressure and the gun was fired up the yard , simple as that , the smith would then inspect the gun visually and if all was well it was cleaned and sent for dispatch .
i don't see in a country like america firearms makers not ensuring there guns are safe , everyone is looking to sue everyone else over the slightest thing over there , a firearm detonating in your hand could bring you a nice little windfall , if you survived that is ,
also one of the guns i hear explode the most are glocks and they as far as i know are proofed in austria .
