Pro's and con's from a previous owner -
Pro
Definitely MagaForce
Recoil is Very low, due to the 12lb weight unloaded, 13-15lbs loaded weight and the long-recoil gas system.
AR pistol grips will fit, but not ones with enhanced backstraps.
The rear sight riser accepts any -A1 style scope attachment.
Con
10-rnd magazines are difficult to find, 20-rnd drums are near impossible.
AR pistol grips will fit, but not ones with enhanced backstraps.
Milling off the rear sight riser and attaching a Picatinny M1913-spec rail gives a much wider range of sight systems.
FMCO used to have magazine pouches, today you'd have to get them custom made, but that's too difficult nor expensive.
I saw one for sale at a gun show in early March. I'm pleased to say that the $1,214.00 I spent in early '91 was a fantastic buy.
