Hi,

Just taken delivery of my 15-22 MOE and bought a Supressor to swap for the flash hider. Didn't bother trying it in the shop as I thought all the threads were the same, and neither did the gun shop owner.

Slightly disappointed to get home and find the thing doesnt fit!! Dang it!!! The thread on the rifle appears to be a bit finer than the thread on the supressor. I guess the problem is having a US rifle and a UK supressor?

So, do I get an adapter to make it fit, or am I going to have to get the supressor swopped?

By the way, I absolutely love the lightweight, compact feel of the gun, cant wait to try it. Only had it a couple of days, and the girlfriend says I look "gay" carrying it around everywhere LOL!

Cheers - David

You should be able to find an adapter on the internet using a google search.

If you intend to get additional firearms to use the suppressor on, I would go the adapter route.

If this is the only firearm the suppressor is for, then I would get the correct suppressor.
 
I guess I was looking for someone to post the actual thread dimensions for the rifle? Just being lazy :)

I do not know what is customary suppressor thread pitch in the UK

Nor do I own a 15-22. But I do have several suppressors and platforms to run them on. Using adapters I have been greatly able to expand what works with what.

Based on your description it sounds like you are dealing with 1/2x28 and 1/2x36. Obviously that is a guess

You never told us what thread is your suppressor is marked as.
 
TheSupressor is completely unmarked, not even a makers name. The gun shop owner screwed it off a display rifle and passed it to me. I guess I will be taking it back in the morning. Good news is it is less than a mile :)
 
Congrats on the new 15-22 :)

Most UK .22 Rimmies are cut to 1/2 x 20 UNF threading, so there will likely be a mismatch between the rifle your dealer took the moderator off, and your 15-22.

Options would be to find a mod in 1/2 x 28, or to have the 15-22 barrel chopped & re-crowned/threaded (although that seems to be a bit of a faff) - I'm aware of Riflecraft (UK) having chopped and permanently modded some 15-22 barrels to the legal 12" limit if that takes your fancy...?

should be an adapter out there. Walther's have adapter's that screw on and the mail end is the US 1/2x28. Shouldn't be hard to find one online i would think.
 
The 15-22 has US thread - 1/2 x 28 UNEF.
My advise is buy a SAK Moderator £40. Your Gun Dealer can get it from UK IMPORTERS - JACKSON RIFLES, SCOTLAND.
SAK only do one production run of this Moderator a year with the US thread on it.
Take the old Moderator back to your Gun Dealer to exchange it for the SAK---Job done!!!
Don't bother with the adaptor.
 
yep they and many other countries in the EU are the same. matter of fact in some places i've been, it is illegal to hunt w/o one! I have a buddy that is the groundskeeper/game warden in Scotland on an "estate". he does guided hunts for "beasts" (red stag) and uses a suppressed .270 I had the opportunity to go on one when i was stationed in Germany and got to visit as our '10 year in Germany' reward.
 
So in the UK, where there is an almost complete firearm ban, you can walk in the shop and walk out with a suppressor?
Wow. Sorry to thread jack. I didn't know that.

Acquiring a suppressor in the UK requires a suitably licensed 'slot' on a Firearms Certificate (FAC). You can't just buy one on a whim; you need to satisfy the Police of having good reason to own one and they will provide space for one on your FAC.

Whilst I understand your thinking that firearms are almost completely banned in the UK, the situation is nowhere near as bad as that (although as an ex-pistol shooter - before these were banned - I can definitely say that the legal UK firearms owner has certainly been served several injustices due to the knee-jerk reactions of the legislature... anyway, no politics allowed here, so rant over!).

In the UK you can legally own and shoot the following firearms (note that all UK firearms are based on minimum legal spec of 12" barrel length; minimum overall length of 24"; there are some long barrelled pistols (LBRs) which have a 12" barrel and welded arm brace making up the min legal length)

.22LR rifles & LBPs: any mechanism up to semi-auto (e.g. 15-22) - no full autos though!

Any other (centrefire) calibre, pistol through to full-bore: single shot mechanisms only (bolt, straight-pull). There are many AR15s (and other 'military' rifles such as FALs, Steyr AUGs etc.) in civilian UK ownership, but all must have a single shot/straight-pull mechanism to be legal).

In addition, you can own a Long Barrelled Revolver (LBR) which conforms to the same min length requirements in full pistol calibres (.357/.44 etc.).

Muzzle-loading (black powder) pistols (inc. revolvers) are allowed as 'true' pistols (i.e. not having to conform to the min length requirements).

Over and above this, there are NO limits in the UK as regards magazine capacities, mag release buttons, foregrips, flash-hiders etc. so in that respect we actually have quite a bit more freedom than several US states! The amount of ammo that we can buy and hold is however regulated on our FACs (for example, I can only purchase 5K 22LRs at a time, with a maximum hold quantity of 5.5K).

For instance, I personally own the following:

.22 S&W 15-22 (with several 25rnd mags!)

.22LR CZ455 bolt action rifle

9mm AR-15 carbine (using Glock 17 mags and a specialised mechanism called a 'lever release' interrupted gas blowback system, whereby each round fired will eject the case, but remain held open until a small thumb lever (where the safety normally is on an AR) drops the bolt again)

Ruger 77mk2 .308 bolt action rifle

.357 Taurus Long Barrelled Revolver

and have permission (on my FAC) to purchase another .357 rifle, .223 rifle and .308 rifle in the future.

Many of our club members shoot Marlin underlevers in .357 or .44 for gallery rifle competitions too, as these are perfectly legal and quick enough for action style comps.

Not an exhaustive list (as there are also some pistols held on a Section 5 licence in the UK, including vintage collectible firearms), and perhaps the biggest ? Is the fact that while shooters in mainland Uk had to hand in their pistols back in 1996/7, shooters in Northern Ireland (also the UK) and the Isle of Man...?!?

Very interesting. Thanks you Blue. So what are the "good reasons" to own a suppressor?
As you may know in the US, there are a bunch of hoops. back ground checks, finger prints and as of now 9 to 10 months for approval. I have one due for release next June and one in August.
 
Thanks for your interest! It's very easy for people in the US to just believe that firearms are banned outright in the UK, whereas many folk over here probably think that everyone in the US is given a gun on their (10th!) birthday (yippee ki-yay and all that ;) ). Indeed, the shooting fraternity tends to keep itself to itself in the UK, so many people don't even know what kind of firearms are in UK civilian ownership - probably best, as the media tends to want to vilify anyone who shows the slightest interest in guns...sigh :/

Good reasons for a moderator/suppressor here would be for health & safety (noise reduction) concerns or if the firearm is to be used for vermin control/hunting bunnies etc. (so they don't all scarper after the first shot!).

Y'all think we wait until ten . . . . That is so precious

My Father's 22 rifle was waiting for me when I was born. Now it waits to be passed to the next family member

As an instructor, I have had several students under the age of ten. Now that is the exception and not the rule. They were gifted children and needed to have their skill developed

Let me say thanks for the explanation on the UK. One more question on that thought. While you OWN these firearms, are they stored at your house? Can they be in a wall rack or glass rifle cabinet? Can you toss one or more in the car and head out to a farm for some open air plinking on a whim? Or does the UK control location ans usage as well and what can be owned? How hard are these FACs to acquire? or have lines added to?

OK, that was more than one

Yep, the 15-22 in the UK is exactly the same as that in the US, so all (factory threaded barrels) will have 1/2 x 28 threads (UNEF). Indeed, there are no restrictions on the 15-22 in the UK (no 'compliant' models required here), so threaded barrels, flash hiders, large mags, collapsible stocks are all good to go :)

On the UK FAC questions:

Firearms and ammunition that is listed on an FAC can be kept at the licence holder's home, but must be kept securely - generally this requires suitably securely fixed separate gun and ammo safes. This has to satisfy Home Office guidelines and local police firearms licensing officers, so wall racks and glass cabinets would not really pass muster!

The FAC will also stipulate where the firearms can be used (e.g. mine is for target shooting, so that includes my own range, any that are affiliated to that, and any upon which the appropriate insurance is in place for me to shoot). For over land shooting, the licence holder would require permission of the land owner and the land would have to be considered safe to shoot on - there are restrictions relating to using a firearm near to a public highway, for example.

Obtaining an FAC is not particularly hard, as long as you are deemed fit to hold one and can demonstrate good reason for needing particular firearms (e.g. sport shooting of a relevant discipline, or use for hunting/pest control). Application is to the local police firearms licensing team and requires filling out a form relating to your personal details, medical state (also allowing the police to approach your doctor for info) and disclosure of any previous offences (if applicable). Also required are 2 character references (including one from a club official if a member of such - in order to hold an FAC for target shooting, you need to be a member of a Home Office approved shooting club).

FAC applications currently cost £50. Granted FACs last for 5 years, with renewals costing £40. As an FAC will stipulate exactly what types and calibres of firearms can be purchased, official variation of these is often required to accommodate the licence holder's change of intention as to what firearms he/she wants to acquire. A "one-for-one" variation (simply changing one slot entry for another) is free, but adding any slots would cost £26.

Whilst there is technically no specific limit on the number of firearms you can hold on an FAC, the granting of these is at the approval of the local licensing team. As such, first applications are unlikely to be allowed for a large cache of guns (licensing officers dislike speculative 'shopping lists' on FACs!). Also, many authorities stipulate that a home alarm system with telephone call out is required for possession and storage of 10+ firearms. I'm at 9 slots, and that'll do me fine for a while! On topic: each moderator/suppressor held would also require an authorised FAC slot.

There are many more subtleties to the UK licensing system (each separate county police authority has a different 'take' on the overarching Firearms Act and Home Office guidance), but in a nutshell, that's about it :)
 
Now i know why Most of the Europe hates americans, its easier for us to carry guns there! lol

My fiancee is from Lithuania. I am not. We visit her parents quite often and I refuse to go ANYWHERE unarmed. So after a long battle I was granted a EU firearms permit :-D Its expensive, its a pain in the rear but it legally allows me the right to carry a firearm in any country that is under the European Union :-D Called an EFP which is legal in any state that is a member of the EFP. I understand its mainly used for dignitary forces security, hunters and target competitors but can be generally issued to anyone

Can you guys get those in the UK? I know i visited England and one of the cops I talked to was shocked that I was even issued a permit like this.

Mmm, I'm not aware of a trans-EU carry permit that also allows having a sidearm in the UK (but I live to learn!).

To my understanding, there are some permits allowing holders to (concealed) carry a firearm in the UK on the grounds of personal defence, but these are at the extreme discretion of the Home Office - and certainly not something that a 'normal' civilian shooter could apply for (self/home-defence is NOT a good reason for holding an FAC in the UK!).
