Saw this a while back on the firearm blog and it got the gears cranking in my head. May not add up to much more then thinking of how it would work, but you never know I guess.

What would the technical and legal challenges be in modifying a rifle to feed from AR-15 / M16 Magazines without them being pinned from 30 cartridges?

Would they have to be permanently attached to the rifle and fed from the top like most standard hinged floorplate 700's? Or are you allowed to modify the magazine to fit only in this rifle and have them be detachable? (Have a feeling that is a no-go, but not positive)

Discuss?

****EDIT got the gun!****

Here is the gun with the bottom metal removed and the magazine in temporarily. In talks with a smith over the best way to do the conversion legally so the magazine will not need to be pinned to 5. The most likely path I will go down is having the magazine permanently attached to the gun so it can not be argued that it is detachable and can be put into an AR unpinned.

Interesting idea but
1- mags are the shortest you can use
2- HS, AI and LAR already have 10rds mags
3- bottom metal exists for these AI mags

This is not a legal ruling of course but merely an opinion - if the AR mag had a fitting welded to it to mate to your bottom metal and you manf the bottom metal, you may be able to get a ruling as the mag can no longer be used in any rifle except your bottom metal

Seems like a lot of hassle for a mag that will not work shooting prone

Would be super interesting to see what modification/ interface is needed to use an AR15 format magazine. It's been done, but years ago for NRA High Power Match Rifle class! Somewhere in the neighborhood of around $ 800 USD for the conversion. I've since ignored it; not worth the after tax dollars.... unless someone has come up with a cheaper alternative solution. :cool:

I was just messing around in my shop to see what would be involved in doing this mod. (I sense a money pit in my near future :p)

The scale of the rifle is a bit off because it is a .338 Lapua, not a .223, but you get the idea. The bipod is on the second lowest setting and the mag still does not touch the ground.

(So you know, I removed the floorplate to get it to fit.)

Looks like if I have a custom floorplate milled, this could work very easily.


The only thought I have is how to do the magazines. The way I see it there are three possible options.

1) Permanently attach the magazine to the floorplate. Ie. weld or similar method, and remove the pin. It would be cool to do it with a black windowed PMAG.

2) Have a detachable magazine, but modify the magazine so it will no longer fit in any AR, and will only fit in my magwell. Add materiel on the magazine? Maybe use a PMAG? (More difficult then option 1)

3) Have a detachable magazine that is either pinned to 5 or takes the LAR 10 rounder's. (Defeats the purpose, other then the side effect of having cheap and plentiful magazines. Not going down this track likely.)

Wow I must say that is truly boner inspiring :D

However I don't really see how practical it would be... but I want one nonetheless ;)
 
Simplest way to make this work is to use existing gear.

Take a factory det mag and cut a hole to allow the AR mag to fit, then weld it in place. Voila, permanent change that will not function in any rifle but a Rem. Can use existing bottom metal.

same concept as the 45 ACP conversions in Lee enfields.

I'd like to see someone shooting the rifle in the picture (with the mag) in the prone position. Somehow, I doubt it would work as the mag would put the rifle wayyy too high off the ground for it to work.

It wouldn't be too high. Do you think that the various militaries of the world would issue 30rd mags if you couldn't easily shoot in the prone? I shoot prone with a 30rd mag because it gives me a more stable platform than holding the weapon off the ground, if anything the rifle sits too low but the advantages outway the disadvantages for me.
 
Thats awesome looking... Thats something I always hated was limited round mags in bolt guns.. I converted my bolt guns to AI mags already but if you could get soething like this to work that would be cool..I would prefer to use 20-30 round cheaper AR15-ar10 mags..
 
Alright, I have convinced myself I am going to jump in on this. Funds are low right now until the spring thaw comes and I start full time construction work again, but I am moving along slowly regardless.

Got 2 PMAGS with the Maglevel window from Blaxsun last night, and I put up a WTB ad in the EE. If you got a spare R700 SPS Tactical or 700P in .223 that you don't need... give it to a good home. :D

Found this a while ago and have been in contact, they said they would check with their lawyers to see about exporting to canada. Have not heard back from them and have had no time to follow up.

If some of the dealers would look into this set up I know I would be interested in a couple of them. Then we need a mfg of AR mags to print rem 700 bolt action rifle on the side of their magazines for us.
 
The problem with that is that they are standard AR magazines, so they would have to be pinned. Unless a custom run of magazines made just for that rifle showed up, and were allowed by the RCMP, I can not see any officer or court allowing you to use unpinned magazines that are both detachable and unmodified. (Ie can be taken out and put into an AR.)

Cool though. Shows it can be done.

But will the bold feed from the AR mag?
 
Seems like it does, as the two conversions listed above both take standard factory magazines, and nether one mentioned any modifications to the bolt, feed ramp, etc.

I will find out anyways, I am in the works of getting one from a nice guy on CGN, and I will keep you posted as I move along. :D
