Thanks for the reply's.  I may swap the hand guard and 1901 sight on my cut down "carbine" and give it a try.

Ned, is there a place if can use to figure out the correct front sight blade height?

Thanks again!

Edit: Looked around, looks like 0.43" is correct.  Also know understand difference between 1901 and 1902 sights - some I looked at did not show the peep on the 1902, all I saw was the notch.  Not having to flip up the ladder like on the 1901 to use peep is handy when using a hat - had that issue with the M1917 in a match!!!!  :(  Then again, the sight is much further out....

Edit:  Holy smokes, 1902 handguard cost's more than the 1902 rear sight!  Can anyone steer me towards more reasonable handguards?  Maybe where one can buy the set?
