Ordered one of these standard AR barrel nut mounts from from Midwest Gun works (look at the link) for the Tikka Tac A1's. If my math and scale was right I will be going from 1.6 oz with the factory set up to 1.1 oz (plus or minus some change) with the CMR Mlock in a 12 inch. Rifle is currently the 20 inch barreled LE version. Are their better options than the CMR that uses the standard barrel. Limited to float handguards that use an AR barrel nut....
