http://forums.1911forum.com/showthread.php?t=293278remington says that they take standard novak cut sights. they do not. i just got burned with that. i THINK they take the 330x65 Original GI cut, but i wont know till i give it a try. the standard novak is .495 cut, way too large for the Rem. its a mess, and i called remington and they were no help. i called novak and they were helpfull. they claimed that the Rem sights were made by amscor and were the same as the rock island and dan wesson. i have not confirmed that. brownells were the ones that told me they used the standard GI 330x65. hopefully, i will have the answer soon.
Question?Older post with out a clear answer. Here it is straight from Remington's website.
On the standard Model 1911 R1, the dovetail cut is a proprietary cut at approximately 700.
On the 1911 R1 Enhanced and 1911 R1 Carry, the the dovetail cuts are Novak style.
Novak sights can be installed on the standard Model 1911 R1 but the dovetail cuts will have to be changed. Paducah Shooters Supply and Ahlman's, two of our premier field service centers, can make the needed Novak sight cuts for the R1 for around $100. Going through our premier field service centers will not void your warranty.
For the R1 Enhanced, order Novak cut sights .260 front/.450 rear. Personally, I'm going with the TruGlo TFO.
