These are cheaper and easier.... all my MR and AR's have them.

I don't know who had those or bought them, but mine as much nicer and more elaborate. My Colt guy says that they're probably worth 80% of what I paid for the pistol.
It doesn't matter, as it's a memory piece.
A little diving, and came up with this....

Just got this from a deceased friend's brother. My Colt expert friend, will be cleaning and tuning. The ammo in the ejected mag, was from 1980.
I have a pistol from from many of my deceased friends.....
I've been giving all my old and weird ammo to my FFL, for decades. He's had all kinds of old stuff displayed all over his store. I don't really have any fondness for stuff before my generation in my hobbies.
My first build was a 45 carbine. I'm sending the barrel off for threading.
The second will be a 9mm SBR. Have all the parts, just have to do the form-1.
