i have found metal mags that work almost perfect in the lar8, you have to modify them with 2 cuts and a wack of a hammer ,, they are scar 17 factory mags made by fn, you have to cut the U notch just a bit deeper for the lar8 and fal, and angle cut a mag catch notch on right rear rib, that's all that's needed for the lar8, to work, you should hammer in with a punch the left side mag cutout for the scar17 as it will gouge the mag well of the lar8. and if you want to use as a fal mag , tack weld a lip on front,, they are very heavy steel, and so far have worked flawlessly ,,,, they are not cheap , about $39ea but they work.... not sure or dont know how to post pics of this here. we will be trying the ASC brand scar17 mags for this mod if we can ever find any...asc seems to always be out, i have conversed with them about converting their scar17 line to a regular fal mag it only takes 3 processes like i said..
