benedw60 Posted May 11, 2021 Report Share Posted May 11, 2021 Easy way to tell is a 21 sight has no marking and the sight will also have that royal blue finish Link to comment Share on other sites More sharing options...
gijive Posted May 11, 2021 Report Share Posted May 11, 2021 Here are illustrations of the differences. Colt's 1921 Model Front Sight WWII M1 Model Front Sight The WWII Model will also be contractor marked with an S or AOC. The Colt's sights are unmarked.

lamellarllc Posted May 11, 2021 Author Report Share Posted May 11, 2021 (edited) the reason im asking is I have a m1 front sight from Khar, and an origial lyman sight on my SBR and it shoots about a foot low at 25 yards. barrel is a current production Khar 28 finned barrel.

1921A Posted May 12, 2021 Report Share Posted May 12, 2021 21A on the right. M1 on the left. The M1 sight measured 1.475, the 21A measured 1.460.The military sight is slightly taller. 1 Link to comment Share on other sites More sharing options...

Sandman1957 Posted May 15, 2021 Report Share Posted May 15, 2021 Is it on at 50 to 100 yards? Link to comment Share on other sites More sharing options...

TSMGguy Posted May 18, 2021 Report Share Posted May 18, 2021 the reason im asking is I have a m1 front sight from Khar, and an origial lyman sight on my SBR and it shoots about a foot low at 25 yards. barrel is a current production Khar 28 finned barrel. That foot is easily adjusted out by neatly filing down the top of the front sight. You'll be amazed at how little metal has to be removed. Link to comment Share on other sites More sharing options...
