...OK, I will confess!! I bought a Colt AR-15A4 Lower Receiver WITH the ideal of having the "AR-15A4" filled-in and re-engraved with "AR-15A2." I know that this is a little extreme, but I always wanted a correct looking Colt Defense "A2" with the caliber "5.56mm" markings for the collection.
I have a Colt Sporter Target upper that will be added to this project, but I'll be adding a new front sight assembly with a bayonet lug and swapping out the older Colt Bolt Carrier with a M-16/M4 Bolt Carrier.
The problem that I'm facing with this project is;
A) Finding somebody who can fill-in and re-engrave the receiver with "AR-15A2" in manner that it will be identical the font/style of the original "AR-15A4"... I figure it will be a closer match if I have it fully engraved with "AR-15A2" verse simply filling in "A4" and "hope" that it will line up properly and match... IMHO
B) Finding somebody who can correctly add a spray coating finish like Duracoat type product that matches the current Colt black AND is also super-SUPER flat without ANY signs of a sheen... Since I will be filling-in the "AR-15A4," I will not be able to have if refinished back to the original factory/USGI "anodized" specs.
Currently I'm in a hold pattern till I can resolve these two issues... I was simply going to go with a pre-ban "A2," but I'm not to crazy with the slab-side lower receiver... Yes, its a true "A2," BUT, not a very correct looking "A2." Again, a little extreme!!
