AR-15 magazine five round block

[RCS]

Here is a part you never see and rare to find as most were tossed out. Years ago
when you bought a new Colt AR-15 SP1 sporter the magazines were blocked
to only hold five rounds for hunting. 494864948749488

Yup . . . .
This is what was on my early 1965-era SP1. The floorplate was stamped .223 REM. . . . . .NOT 5.56mm!

A short time later, I found another at a gun show.

pretty common to pull the rivets and take out the U shaped block

I think I have a few at the shop somewhere

My 71 SP1 came with 2 blocked magazines marked .223. Since Washington state did not allow any large or medium game hunting with .223 (at that time) I saw no sense in the blocks and removed them. They were not riveted and have been lost in time.

The early magazine block was drop in

My three digit SP1 shown in first post had the magazines with the
small CAL. .223 stamp which I believe is the first unless you count
the Armalite magazine49489

These early waffle magazines are very expensive now, there are repros available

two pocket pouch is Air force used by others, there are variations and a rare four
pocket pouch too49496

Interesting that you should post about the early .223 magazines. Yesterday I was digging through an old foot locker and buried on the bottom was one of my old Sp1 magazines. I was surprised because I thought I had sold them both with the rifle. Still looks in good condition. I guess I didn't use it much!
