Contact one of the American firearms exporters, I used Gibraltar Arms. It will cost you but if you need the part, you need the part.

Is there any issue importing accessories from another country outside of europe like recoil pads or shims for cast and drop for a repeater?

Not for anything gun related they'll refuse it once they check paperwork ! Then you'll have to get it returned to shipper and hope for a refund.

I never had any bother bit it was only odds and sods I got through addresspal. On another note I never use my cousin for fear of ITAR on their side.

I doubt that one can use a US Address and find somebody to send something gun related on to Ireland. If it was that easy, the US gun manufacturer would sell spare parts to Ireland. Also sending as a parcel is probably also a bad idea, customs might open it ( it's from outside the EU), and apart from paying customs, maybe a fine will have to be paid.

So the whole undertaking is a bit risky.

The majority of the Irish population wouldn't know a barrel from a buttstock, and apart from what they have learned from MSM news propaganda and the Hollywoo fiction factory and Call of Duty games. They would be too easy influenced that any sort of liberalisation of gun laws here would cause us to become the Southside of Chicago in an instant!

Just to give an example without going OT or into RTKBA country here,pepper spray,which is freely available and sold virtually in any newsagent on the continent and even German police giving them out to 16-year-old girls on personal safety talks in schools,is considered a prohibited weapon here,and in the Uk.

Despite numerous sexual assaults and two murders that could have been avoided here in Ireland and the UK had the women been carrying a can of pepper spray. The attitude of even women organisations here and the UK is "It will be like America in no time! And guns are not the answer!" So with that attitude, take a WAG as to how the GP would view looser legislation?🙄

So you look about the EU for the same model,and purchase it in the EU from a country that has favoured trading for such with the USA.Also ,there are some US companies like web buy in Texas that will export to to Ireland no problem,once you sign an export certificate that they email to you before the sale goes thru.I bought two scopes off them no trouble that were unavailable in the EU at the time.So it can be done.Parts ,go to Brownells Germany,if it isnt on their website, email them and they can proably special order it for you from the US patent company.
