[ARCHIVED THREAD] - Keyhole Marked Upper

Posted: 3/26/2006 7:37:59 PM EDT

Looking at a "Keyhole" marked upper receiver and have only seen the pics. What type of receiver is this? I tried looking for the symbols chart but can't find it.

After closer inspection its a keyhole with 3 dots (vertically) inside the keyhole. ?? any ideas?

The upper forging was made by Cerro Forge. Several mfgrs use Cerro uppers (my bushy is one).

Can't tell the upper manufacturer from the "keyhole" symbol.

That's a forge marking from Cerro forge, and many manufacturers use their products; including Colt (but would also be marked C next to it), Bushmaster. DPMS, and RRA to name a few.
