G'day everyone. Was just wondering on peoples thoughts about moddifying a remington 7615 in .223 that takes AR mags to fire the .458 socom cartridge. For those that don't know in Australia we aren't allowed to own semi autos and recently we have been stopped from putting 30 round mags in 7615's because they believe them to be converted into a assault weapon or some bs. Thought this would be a good project and i would have something unique at the end of it. Any feedback from someone that is knowledgable about how difficult this idea is would be appreaciated. Would it just be as simple as changing to a .308 bolt and a new barrel and feeding moddifications or would it be alot harder than that.

Save yourself the hassle - the bolt and barrel extension are different on the .223 model.

Start with a .243/.308/.30-06, hopefully they are cheap down there like they are around these parts - and add the 7615 magazine adapter.

A portion of the magazine adapter sticks up in the front and will need to be cut down a bit for case body/shoulder clearance.

Next to the last page of the pricing list is where you'll find the 7615 listings.

I bought the whole magazine adapter as an assembly(armorer contact), but I don't see a listing for the whole thing there.

Here's the related pieces I'd be looking for.

F300969 V-I 7615 MAGAZINE INSERT SCREW $ 3 .20
F301032 V-A 7615 MAGAZINE INSERT $ 3 9.00
