I've got two both Bushmasters. Never had a lick of trouble from either of them. The 24-inch heavy barrel Varmint with 1-8" twist and two stage trigger is accurate for anything you could possibly need a .223/5.56 for. The other is a 16 inch tactical and it's plenty accurate too.
How do you like the 24" varmint, any negatives? This one is on my short list.
