just can't decide to go with the 20" or 24" Besides the weight is there any disadvantage to the 24"?
also i notice there is an option for the 1:12 twist on the 24" i plan on using 40-55 gr varmint loads. so which twist is recommended? i know you can't overstabalize a bullet, but i imagine there is a reason why the 1:12 is offered.
and one last question. if buying direct from RRA, is there any other type of gas block available? would rather not have sight base type block.
