AI - 12mm to Picatinny Adaptor - Does it exist?

[Roy W]

Does anyone know if there is a picatinny adaptor rail which fits onto the original dovetail on an old AI PM?

 

I am trying to mount a PMII onto one using an AI 34mm one piece mount, but the turret housing touches the bases and won't allow the rings to close around the tube properly, therefore I want to use a picatinny type mount but need to convert the dovetail to accept it.

 

I believe it is a 12mm dovetail fitting?

 

Thanks

I'm pretty sure I have seen the centre milled to accept the turret housing of the PM11.

Mill a slot in the base of the mount to accomodate the belly of the erector housing

 

Or buy a length of 12mm dovetail picatinny from AI and the pins / screws to fit this to your action

Sporting services sell the modified mounts

Many thanks for the replies. I will look for a modified mount as I don't want to drill and tap the original receiver

My AW came with a shallow 20 MOA picatinny rail bonded to the 12 mm dovetail. The picatinny rail is unusual inasmuch that it fits as a female rail over the original dovetail. There is no way that's going to move.

I don't know if this is a later adaptation ( my AW was one of the last before the AT was introduced) or if it's an after-market offering.

Roy, I have 4 AI mounts in a drawer if you want one to hack about at. Dovetail fitting and came off early .338s I think with PM11 3 -12 x 50.

[Roy W]

TSG, that's a very kind offer but my hacking will consist of a hand file, several cups of tea and a DIY finish.

 

Are they 34mm?

 

The adaption that Brillo was talking about is the kind of thing that I was after, but one which gripped the dovetail by means of being nipped up with allen bolts like a set of rings.

They are 34 mm. Drop me a PM with ur address and I will put one in the post if you want. You may find a Picatinny adapter in an air rifle magazine but it will be made of cheese I suspect.

Alan Rhone http://www.alanrhone.com/products.html have loads of adaptors, rails etc. They may be able to help if you are still looking.

Roy,just get a groove milled across a mount as suggested. Works perfectly.

When I needed the dovetail to pic adapter Sporting Services were flogging these:

SS were charging £125 a pop - don't know if they still stock them as this was a couple of years back now. If not you can probably source direct from the US.

 

I'm not sure you can order the factory adapter (i.e. as installed on a new rifle) as a spare part...if you could, I think SS would be flogging that rather the aftermarket one....
