dirtypool40 Posted June 28, 2005 Share Posted June 28, 2005 OK, newbie to Open / Tac 3-gun. Regular carry handle mount, on an M4. If I zero a good optic on an AR then remove it, will it still be zeroed when I strap it back on? I want to switch back and forth between iron sights and TAC class at matches or between matches and don't have time to rezero every time. thanks in advance.

BigDave Posted June 28, 2005 Share Posted June 28, 2005 LaRue Tactical (click here) I have the Aimpoint and SPR-E mounts for that very reason. So far, so good as far as repeatability, at least at close range. I haven't tested it at any distance, but I'm confident that the repeatability is great. Mark's stuff is spendy, but it is rock solid and high, high quality. You will get what you pay for. Link to comment Share on other sites More sharing options...
dirtypool40 Posted June 28, 2005 Author Share Posted June 28, 2005 I guess we're on the right track, but I don't see anything for carry handle mounts. Link to comment Share on other sites More sharing options...
EricW Posted June 28, 2005 Share Posted June 28, 2005 DP, I just don't see repeatability happening on a carry handle mount without some serious fitting. I think it would be easier and cheaper to simply change out the upper receiver for a railed one. I was able to remove and replace even my B-Square mount without too many gyrations. I just put a witness mark on the mount and the rifle so that I got it back in the same spot every time. E Link to comment Share on other sites More sharing options...
dirtypool40 Posted June 28, 2005 Author Share Posted June 28, 2005 EW, this is a hypothetical in case I wanted to use an issued M4, but I see your point. My match gun is built on a flat top. Just trying to see if it's possible. Link to comment Share on other sites More sharing options...
jhgtyre Posted June 28, 2005 Share Posted June 28, 2005 I guess we're on the right track, but I don't see anything for carry handle mounts. <{POST_SNAPBACK}> One of our local 3 Gun gurus said something along the lines of "I hope all of my competition uses carry handle mounts." You might think about getting that flat top. -ld Link to comment Share on other sites More sharing options...
davidwiz Posted June 28, 2005 Share Posted June 28, 2005 Using the Trijicon ACOG mount for my TA-11, I can remove it and put it back on w/ no loss of zero. Link to comment Share on other sites More sharing options...

Bronco Posted June 28, 2005 Share Posted June 28, 2005 Long ago before flattops were common I used a B square carry handle mount that would come back close say 2". The thing you run into with carry handle mounts is the height above the bore, on close targets its an issue and also with some of the ports in walls you'll stick the barrel through the port but all you see through the scope is the wall.

dirtypool40 Posted June 29, 2005 Author Share Posted June 29, 2005 how often doe that happen? Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted June 29, 2005 Share Posted June 29, 2005 How much bending can you do to the carry handle before anyone notices or complains? Back in "the day" we'd pinch the sides of the handle slot until the scope base was a snug fit. Then, use a witness mark ont he tightenign nut to get it tightened to the same spot each time. We could get a remounted scope to come back within an inch at 100 yards. Link to comment Share on other sites More sharing options...
George Posted June 30, 2005 Share Posted June 30, 2005 As Patrick has pointed out, you will have to DIY if you want "real" return to zero in a detachable on a carry handle. If you use a flat top and the Larue mount Dave mentioned, or the Armalite one piece QD scope mount, you will get a "real" RTZ As far as optics on a carry handle goes, just don't take upper A/B shots unless you have absolutely have to and make sure you test and practice the offset. Saying it and doing it are two different things once the timer goes beep ;-) Welcome to 3 gun! -- Regards, Link to comment Share on other sites More sharing options...
Garrett Posted June 30, 2005 Share Posted June 30, 2005 I've used the ARMS throw lever ring mounts, and have had no problems returning to zero. I would use these to switch between a red dot and a 3-9x scope, and I never had any problems. More recently though, I've mounted a Vari-X II 1.5-4 on my AR (using these rings), and haven't had the need to remove it. http://www.armsmounts.com/catalog.php?action=124&item_id=72 Link to comment Share on other sites More sharing options...
stingerjg Posted June 30, 2005 Share Posted June 30, 2005 OK guys. I think what dirtypool40 is looking for is a mount to go on his ISSUED rifle. I dont think he has the option of changing it to a flat top reciever. When i was in the Army, i had a cantaleaver mount for an Aimpoint. I took it off once to clean the rifle. It wasent even close to being zero'd. I may suggest if your going that route, is to get a laser borsight device to re check your zero. if you check it b4 you remove the optic, and it changes in the process, you can get it really close.

kellyn Posted July 7, 2005 Share Posted July 7, 2005 My view of "repeatability" is right out of the X Files: TRUST NO ONE. I have had sights removed and replaced and come back to zero but I've also had the same sights not come back to zero. One MOA off is 3 inches at 300 yards. That's quite a bit on a 8 or even 10 inch plate. Would you go to a major match and just pop your sight on? Not me! Link to comment Share on other sites More sharing options...
