Do Magupul Ranger floorplates fit LAR-15 mags?

Newbie question. Does the Magpul pmag fit in the LAR-15 pistol. The reason I ask is, if it does fit could it not be argued that the pmag is an aftermarket LAR-15 pistol mag. As such could It not be purchased pinned to 10.
As I read the law the weapon that the mag is put in is not where round limit is decided but the wepon that the mag is designed to fit. There for a pmag pinned to 10 would be technical legal to use in my ar-15.

The only legal way to have 10 round PMAGs would be if Magpul were to make a dedicated 10 round version and mark it as being intended for the LAR-15 pistol.

I have modified my LAR-15 magazines by fitting the Ranger Plates and modifying the follower to retain the 10 round capacity. I do this by marking the rear leg of the follower at 1.025" from the top, cutting with a hacksaw, and filing to fit. A little trial and error is normally required to allow the full magazine to be inserted with bolt forward without excessive force while preventing an 11th round from fitting.
 
Just to report, found some USGI Ranger floor plates at Full Spectrum Gear in Petawawa, and with some judicious sanding down of the follower legs was able to get them to hold ten just fine. Thanks everybody for the advice!

Tks for the tip. Just ordered some from them. A kick in the teeth price wise though, but hey, begger can't be choosers.
 
exactly 2 weeks, usually I get a shipping notice within a day or two. Is it possible yours have been shipped but you are waiting for the items to clear the border? I use a US box as I am only a 5 minute drive from the border crossing, generally speed things up alot but with there mass buying panic down there things have slowed up quite a bit.
 
So you mark the follower from a flat spot on the top of it and mark 1.025 then cut right.Do you know how much your cutting off it's my first time and I don't want to screw it up. Thanks
 
Correct. The solution is to file down the follower posts by 2-3mm so that you end up with 10.5 rounds and can load on a closed bolt (actual amount depends on the type of follower, which has varied with production).

Thanks I was looking for that info, so now I ordered 3 sets of ranger plates from brownells.
