BudsGunShop.com - Is this the heavy barrel?

Mike, yes sir to both. This has a 20 inch heavy barrel and all howa rifles purchased in the U.S. are guaranteed to deliver sub-MOA performance of 1 inch or less with premium ammunition. Hope this helps.

Hi Mike and welcome to the Buds Community. This UPC code rifle has a Hammer Forged 20 heavy barrel option with Muzzle threaded ½-28 with tread protector, Blued finish & 1-8 Twist rate. Cheers and stay safe!

Hi Mike, yes sir, this is the heavy model that comes with a No. 6 barrel that’s chopped at 20 inches. I am not finding any information that this has the MOA guarantee.
Stay safe & have a great day!
