I purchased an AAC SD 7.62 about four years ago. This was my first suppressor and I was never happy using it on my bolt rifle because the zero shift wasn’t always consistent. If I had known more then about different suppressors, I would have gone a different route.
At any rate, I sent the suppressor to Nick Bosco, owner of ECCO Machine, to have the mounting system change to an Area 419 Hellfire system and I’m completely happy with the end results. The machine work is excellent, I have a consistent 3/4 MOA zero height shift and accuracy is as good with or without the suppressor. I’m using it on a 6mm Creedmoor bolt rifle with a 26” Bartlein MTU profile barrel.
The modification cost around $300 with machining work, adapter and shipping.
I highly recommend using ECCO Machine, the quality of the work is excellent, Nick answered all my questions about having the conversion done and had the suppressor back to me in 2 weeks.
