BayouSlide Posted January 9, 2009 Share Posted January 9, 2009 I seem to remember some conflicting info from what I've read in the past regarding new parts versus used parts versus the need to check with go/no gauges, etc. I'm wondering if I could safely switch parts from one rifle to another, if need be, in case of breakage during a match. Yeh, I know, just use the other rifle, but each are set up with different optics/barrels/etc. for different types of matches Help a brother out with the straight scoop on this issue...you guys I trust Curtis Link to comment Share on other sites More sharing options...
warpspeed Posted January 9, 2009 Share Posted January 9, 2009 I have done it with no ill effects but, i have a set of go / no go gauges and have checked to make sure everything was OK. There will be minor differences but 3gun, I have seen no issues on accuracy. The ideal set up if you are trying to save $ or just just cant get parts is to have a bolt dedicated to the upper and switch the carrier. I can see this especially fi you have a JP LMOS or one of the Ti carriers and the budget will not allow for 2 or 3 of them. The bolt is the real key.

BayouSlide Posted January 9, 2009 Author Share Posted January 9, 2009 Thanks, warpspeed. Or, I guess a separate/related question would be the benefit of having at least a spare bolt that was GTG after checking it in both rifles, since the carrier is more interchangeable without issues. I'm starting to think along these lines as I have a Bushmaster carbine that is getting up near 5K rounds, nearly all XM-193, on it's original bolt.

Dan Sierpina Posted January 10, 2009 Share Posted January 10, 2009 AR bolts have been closely held to dimensional specifications. Unless your barrel was chambered by a benchrest gunsmith, swapping bolts during a match will get you through the match. The correct method is to check each bolt with headspace gages for your barrel.

warpspeed Posted January 10, 2009 Share Posted January 10, 2009 The go / no-go gauges are very small, as you would imagine. I'd be happy to loan them to you to check if you need. Link to comment Share on other sites More sharing options...

Thanks, warpspeed. That's really nice of you. I just may take you up on your offer. At this point, I'm thinking about just buying a complete spare BCG and checking the spare bolt for clearance in both my rifles. Curtis Link to comment Share on other sites More sharing options...

Curtis No problem. They sit in a drawer most of the time. PM me when you need them. Link to comment Share on other sites More sharing options...
