If I were to buy one of those Colt SP1 uppers from CDNN (they have a teardrop forward assist and birdcage flashider) and mated it with a current produciton A2 lower (such as, say, a Rock River Arms), would the resulting rifle be historically accurate if I swithced out the grip with an A1 grip? Would an SP1 upper even fit onto a modern lower of a different manufacturer? Should I stop being cheap and just shell out the extra $200-$300 for a complete SP1?  Thanks. |
| the uppers that CDNN are selling, are not SP1 uppers, they are real colt A1 uppers, and will fit any standard lower with the small pin. I bought the A1 upper from CDNN with the bolt carrrier and charging handle, when they had those, and it was a brand new upper in the plastic, and fit perfectly on my A2 lower...........as for historical accuracy, the A2 lower is a bit different from the A1 lowers, but not enough that will be that noticable, if you take a A2 lower, put athe shorter A1 buttstock on it and a a A1 pistol grip, it will look right.........the only thing is that the colors won't match, the CDNN A1 upper is gray, and the color of all the A2 lowers is black. |
