RAZZ Posted October 17, 2011 Share Posted October 17, 2011 Let's say you have a 16.5" middy laying around, and you want to do some 3-gun. The barrel is a very heavy 1 inch from chamber to gas port, and .720 to the muzzle. I want to get it turned down to take some of the weight out of it. What diameter would you recommend getting it turned down to? I'm planning on .700 for the full length, unless you guys can convince me otherwise. Thanks.

Jetracer013 Posted October 17, 2011 Share Posted October 17, 2011 I would think if you have it turned down to a single diameter the whole way, you would get some serious barrel whip. Most barrels vary in diameter to reduce this. If you want to drop weight, I would try fluting it. Link to comment Share on other sites More sharing options...
StealthyBlagga Posted October 17, 2011 Share Posted October 17, 2011 Paying to have the barrel turned will cost more than just selling what you have and buying what you want. Personally, I'd stick with the 16" HB you have - I doubt you will notice the weight reduction in the handling, and the weight will dampen recoil and reduce the effect of heat on accuracy. IMHO many folks on this site have an unhealthy obsession with light weight rifles... 3-gun anorexia nervosa Link to comment Share on other sites More sharing options...
MarkCO Posted October 17, 2011 Share Posted October 17, 2011 You just want to make sure that the gas block you use fits the diameter on the gas port, and that it will clamp or slide on as the case may be. Barrel "whip" won't be an issue with a 16" as long as you stay above .650 or so. Link to comment Share on other sites More sharing options...
RAZZ Posted October 17, 2011 Author Share Posted October 17, 2011 It's an HK MR556, so 'getting one in the diameter I want' isn't an option. They only make one size, and no one else makes a barrel for it. It comes from the factory as a 9+ lb carbine-size AR, which is a little obese. Sure, I could do a few more pushups, but I think I can get away with taking a considerable amount of weight out of the barrel without compromising accuracy. We'll see what Adco says.

oak hill Posted October 17, 2011 Share Posted October 17, 2011 Just use it! You can always do mods later as you find you have a preference towards something else. Link to comment Share on other sites More sharing options...
shooter57 Posted October 19, 2011 Share Posted October 19, 2011 Sell it or trade it for what you need instead of dumping more money into a gun only you will have made and you may not like the results. Link to comment Share on other sites More sharing options...
