Just bought my first mini, used, off Gunbroker. Mini-30 in factory configuration with only a Simmons 3-9 added. Excellent condition, may actually be unfired. Paid $546 including shipping and transfer fee. My plan is to buy a few ruger factory 20 rounders, an accurizing system, a sling, and muzzle brake/flash hider. Can anyone give me some advice on the best way to do my planned mods (i.e. threaded brake or bolt on, good barrel strut systems, etc.) or any other mods I should consider? Also, I don't want to spark controversy, but should I shoot russian ammo out of this thing (wolf, brown bear, golden tiger, etc)? I've heard debates on both sides of this issue. Would like some clarification. Thanks in advance!
