Re: New Remington AAC, is the Wyatt's metal good?
I would say Pass on the wyatts, Save a litle extra cash and be ahead in the end( only about 100 difference with inletting for an ai style) go with anyone of the ai mag compatible systems.
CDI, Hooper, Badger, Seekins,or others.
Mags are easier to use, readily available, shorter ( prone shooting) and if you ever were to sell it will be easier to get your money back.
If comp is not your thing I suggest sticking with a bdl style guard, from PTG, Williams, or Badger ( the PTg is a drop in, others will rewuire inletting)
Good luck, would like to see pics when completed
