Best options for mr556 modification to 416
Looking to get my mr556 modified into a hk446:
Vented Gas Block Modification (for can)
Shorten to 10.4″ and Thread 1/2 x 28
Titanium Barrel Nuts and Gas Pistons
Reached out to investment Grade Firearms a few times and don't really get answers to questions. I hear they are backed up.
Hoping for a quick turnaround, filing tax stamp next week. Used Michaels Machines for a HK11 and had a good experience l, based on recommendations here. Looking for another quality job with a decent turnaround. Searched for recommendations, but would like to hear recent experiences.
