This is one of the finest boards on the 'net. Lots of reviews and refrences. This one is on magazines: Refrence and Data
Ten round or "hunting magazines" are tough to come by, as they are usually custom made.
Thirty rounders protrude too far below the reciever, and they are heavy when fully loaded.
Twenty is the gold standard and what you'll find the most of.
What I didn't ask was if you need metric or inch pattern magazines?
The diffrence is in the front edge (bullet tip end) Metric has a small punched out tit thats triangular in shape. Inch pattern has a bar accross the front jinda like the M1A or Ruger Mini-14 magazines.
Your reciever MAY
accept both. A search of the FAL Files should illustrate pictures of the diffrence.(send me a PM or e-mail if you need help).
I'd like $5.00 each for my magazines and they are all in good to very-good condition, just let me know.
