Re: Accoracy Int AE ?
To answer your question on the barrel ordering without the receiver shipped to GAP. Yes and you will need to ask them for their requirements. A barrel for an AI to us is a barrel, in an out of a receiver which is 8 years old with a new barrel, torque, headspace check and you are off and running, just that simple. But this is not normal as you know with other weapon manufactures. If they request the receiver that is entirely up to them for direct replacement barrel. I would say on the AE, if you are going with the .308, you will not find a better replacement price on the original barrel than the AI OEM barrel. So I would highly recommend you contact one of our distributors for pricing. So hope this answers your questions.
On the barrels in and out with mutiple calibers wearing out the threads, receiver or parts. The answer would be no. I have been doing this exact operation for near 15 years with these weapons and no reports of issues from either myself, factory or customers to date. As another stated, it is an AI, enjoy the simplicity, follow a standard installation, maintenance and cleaning procedure and shoot.
