I can probably do this at some point this week, but I thought I'd seek the knowlege of those who have been there.
I'm having my LR-308's fluted stainless steel 24" barrel cut down to somewhere between 18" and 20" and recrowned soon.
While I am at it, I am having the barrel threaded.
Because I'll be cutting into the flutes, I will have to cap the end off with either a thread protector or muzzle brake.
So here's the first question...
-- What is the barrel diameter on the bull barrel at the muzzle? DPMS is strangely non-specific on this-- saying "roughly 1 inch."
I haven't been able to read anywhere that says the exact diameter. I suspect that it is either .920 or .936 based on some conjecture on my part. (I don't have any calipers handy, but my FIL has a good set that I may check this week)
I need to find this information in order to determine what muzzle brakes will fit easily to this barrel.
I may swap out the gas block while I am at it. This is where I start to believe that my barrel is .936. The largest diameter gas block I have located is .936 and I suspect that is the one I will need.
So, second question...
Is there any difference between the muzzle diameter and gas block diameter on this barrel? Does anyone have a diameter at the gas block?
I appreciate anyone's help that has knowledge on this subject.
Final question...
In practical terms-- from the long range shooting crowd-- what effect would cutting my 24" barrel down to -- say 18" or 19" have on my maximum range? I realize that velocity is affect, but would this have a practical liability for the .308 cartridge?
My shooting doesn't go past 600 yards-- ever. However, I would like to retain as much of the capabilities of the rifle that I can while balancing those with practical usage in terms of being able to maneuver the rifle sans a benchrest.
I appreciate the input you guys can provide!!!
