lol, so can someone please enlightenment me about this model (and any similar models)? I ASSumed because it was "A2" it was the updated A2 lower receiver forging. A few pics I've seen lately seem to show this is clearly an A1 forging. Is that correct? Are they large or small (pivot) pin? LE markings? Any other thing of note? I'm by no stretch a Colt SME, but I've been P1 fan since I joined this site. I'm still amazed at some of the stuff I learn about Colt ARs. |

As noted Colt did many “transitional” variations when moving from A1 to A2. Colt did eventually move from the “slab side” Lower used on most SP-1s to the standard “fenced” lower but there is no “A2” lower. The fenced lower was standard on most M16/M16A1 decades before it was used on the ARs. |

Green label guns: pre-94. slab side lower, large 2-screw front pin, gray anodizing, no sear block,0.155” fcg pins. White label guns: pre-94. A2 lower, large 2-screw front pin, gray anodizing, no sear block, 0.155” fcg pins. Blue label guns: pre-94. These were all over the map. A2 lower, either a large 2-screw front pin or a milspec front pin that is retained with a single screw on the left side, gray anodizing, pinned steel block. Of the guns with milspec front pin, some were drilled for the pushpin spring and detent and have the weep hole, some were not. I’ve also seen slab side guns with the sear block. All blue label guns would have 0.170” fcg pins. Post 94 colt made lots of AR-15A2 Gov’t Carbines. Some were leftovers from the blue label guns that were assembled from parts on hand after the ban. Then Colt went to the A4 type receiver forging, black finish, restricted markings on the right side of the magwell, 0.155 fcg pins, unmilled web of aluminum autosear block. The 2010-2015’ish guns again had blue labels on the box, but are not what I’m referring to above wrt pre-94 Blue Label guns. |
