I'm looking to replace the factory DBM system with something that holds more rounds. My rifle has the A4 stock and I hate the factory mag system. I've seen pictures of the same rifle with bottom metal that excepts AICS mags. Any help will be helpful, thanks.

OOHHHH

Thanks for the heads-up. I was under the impression this was something I could do myself. New to the precision rifle thing and still researching...

How much work for a good gunsmith to do this?

Thanks,

Re: FN-SPR bottom metal

I spoke with Jeff about this and he says that his DBM is based off of the FN factory DBM inletting with slight modifications to the mag well portion.

From this picture you can see that the front tang of the DBM is rectangular in shape compared to the standard hinged floorplate that is rounded off.

Here is picture of the Williams one piece bottom metal that FN is using. You can see how much more rounded off it is.

Hope this helps out.
 
Re: FN-SPR bottom metal

I have the FN PBR with DBM, and I have the CDI unit also, it mostly fits the inlett but seems to need some minor work. I didnt get to much into it when I was home short of just piddling with it. But it doesnt look like it needs much work
