Has anybody attempted to fill the large holes & re drill to Mil Spec? The detent hole will also need to be drilled. What say you? |

I don't have pics to show but did it to a Colt Sporter about 10 years ago. I had a bolt that was same diameter (don't remember the exact size). I tapped and used Locktite on the bolt straight through both ears then used a Dremmel with cut-off wheel on both sides of each ear. Used a small hole upper and center-bore bit to locate drill placement and finished with Testors black model paint with enough white to match the "Colt gray". Had zero problems with any small-hole uppers I used on it totaling about 3000+ rounds and sold the rifle with the buyer aware of the mod. However, with the easy availability of normal small-hole lowers today, I wouldn't do it again. |
