bringing stuff back from the usa

[the running man]

Ok I know barrells and receivers are a no no, but can I bring back. A trigger assembly or bolt for a 10/22? I'm already bringing a load of mags and a stock or two of which I'm happy they are legal...

Secondly would it all need separating from its original packaging to convince that it's second hand or is this just in the eye of the beholder?

Bolt = NO (pressure bearing part)
Mags = ONLY 10-rd or less

You would need the new bolt as a separate slot on your FAC before you tried to bring it into the UK. Really don't know what the situation is on the exporting side.

When I asked about bringing mags back I got varied responses when it came to mags for .22's, some saying the same restrictions applied to full-bore guns and others saying that while the restrictions did apply, they were 'never' enforced for .22 mags. Not sure I'd want to run the risk without being certain as the potential penalties are severe. I'd want a letter from the BATF or similar to give to TSA.

A mate came back from the US recently with some 30 round P mags in his hold baggage. When he got home he has a leaflet inside his case which stated his case had been examined by the TSA. The mags were still present.

Ok helpful stuff! It's a no on the bolt then! And I'm only getting 10 round rotary ruger mags anyhow...

That has been my experience also.
Last year I brought back one 25 round Ruger mag, one 10 round Ruger mag and one 35-round S&W mag. I also had a large container of Strike Hold and several dummy 12g and .22 cartridges.
All of this was in my checked back. TSA inspected the bag but didn't remove anything.

How about a replacement drop in 10/22 trigger...

I should add that I always put the firearms related stuff in one plastic bag, with my FAC inside also.
I've only ever had one hiccup, which was when I brought back a tray of disassembled rounds provided to me by a crime lab based in the US.
I was flying out from Colorado Springs to Denver and then London. At Denver, just before we boarded the plane, I got called to the front desk and I was advised that these items had been detected. Surprisingly, they were trying to do me a favour: they didn't mind that I had the items, but they were concerned that I might run into trouble with the UK customs when I landed at London.
I thanked them and said no problem, I was going to declare them at customs.

When I arrived in London I collected my bag without issue and then declared the items at customs. Due to the nature of the materials they could not make a judgement on the spot and had to refer the items to a specialist. I left them at the airport and went home.
The next day I got a call saying I could collect them. Note that I had certain research documents which greatly improved my chances of retaining the items, compared to somebody who just wanted the rounds for a wall display. I have an open research project involving gunshot wounds, so it is reasonable for me to have these items and X-ray them.

I would be happy bringing that back, it isn't a pressure bearing part.

Bolts are covered by ITAR - so you'd need an export licence to bring one out

A good rule of thumb = if any part that you want needs an FAC slot, then chances are it's ITAR restricted.
