So when they first became available I purchased a FAB-10 lower (and I payed a lot for it). When I could afford it I bought a kit and built the rifle. At the time I was stoked to have something that at least looked like an AR. So fast forward to today and the FAB-10 is pretty useless. So I purchased an AR-57 upper and I figured it would perfect for the FAB-10 lower since it ejects brass out the bottom. I figure I just Dremel out the mag well and I'm good to go. So now I just need to get the encouragement to actually take the Dremel to my gun, I don't want to screw anything up.

I don't think you can screw it up!! If all you want to use it is for the AR57.

On a plus note, you can get a bolt action upper for it also: http://www.tactilite.com/models/view-all-products.html I think the gas emergency escape is through the magwell, so that needs to be open!

its worthless as is, at least you would have something functional. i would not hesitate, just make it clean.
add- a bolt action build would be a great use for that lower as well, and you wouldnt have to chop up your expensive lower.
either way, good choices.

Do it. Dremel will cut thru aluminium like butter

Yeah, that's why I bought the Ar-57 upper. Plus this gives me an excuse to build another lower

I milled one of mine out to make it a different caliber for a friend. We were gonna do a .22 but decided to mill it to accept a 6.5 10 round mag. We went a different way with the build on a different lower. Have it milled out. it will look better.

Dont do it. as a lower it is worth less, as a collectors piece its worth something as its an image of an era gone by.

leave it as is.

Speaking from sad experience (some people,*cough*:kest:*cough*, given a dremel tool and a 16 ton block of steel, would manage to break the block of steel), I would strongly recommend having a professional machinist open up the mag well. Then again, with lowers costing as little as they do (relatively speaking), maybe you should just buy a new one and then donate the lower to the NRA Museum once the AWB is consigned to the ash heap of history.

I've never seen or heard of a FAB-10 until now. What a wonderful piece. I'd keep it as-is and just buy another receiver. AR15 receivers are plentiful. The FAB-10 would still make for interesting conversation & put a smile on ones face when reminiscing about the by-gone days

Manufacturers should bring those back & call them 90% receivers

I LOL'd when I saw that. Reminds me of one of my best friends...

fact of the matter is he can actually make it work.
