The photos are a little too small for my tires eyes, but the bolt carrier appears to be Colt from the large firing pin retainer pin hole on the right side. The bolts' chrome finish and the gas key looks too mat to be a Colt. Cotter key is not early Colt. Firing pin looks to be AR-15 not M16. Cam pin?
Have seen the tri-stakes but can't recall. Correct for 601 or 602. |

I agree with PrivateSnafu.Carrier looks Colt. Bolt, gas key,cotter pin appear non colt. Original stakes would have been a single small round stake on each screw in the area between the screws. Keys were often re-staked,but your pattern is not consistant with any Colt I've ever seen. Appears to be a rebuilt set to me.
3/4 round gas key may have been on late 601,definitely on 602 and very early 604 |
