FN SPR 5 round mags

[wichitaguns]

I managed to grab some fn spr 5 round steels mags from Brownells.
They just ran out, anybody got any other go to places for fn 5rounf mags?
This is for the TBM

eBay or gun broker have been the only places I have been able to find them.

Is that what came in the SPR guns as well?

 

[Mooseknuckles]

No, the 4 round mags are what came in the spr a1 guns. You had to install a tbm bottom metal to run the 5-10 round mags. Unless you went with a ptg or cdi bottom metal.

CDI converted my SPR which is why I was asking. Think I still have the bottom metal and a mag or two but I haven't messed with them in years so I couldn't remember what the deal was with them.
