Don't know I just went with the base model And planning on upgrading later when Financial situation improves
I'm back on a rig Wednesday I bin off work for seven months
I got my MH used the darrel was way too heavy
I replace the barrel with a thin one and will put in a order for two carbon fiber hand guards and matching buttocks later this year haven't picked out a lightweight stock yet can't be something that's not going to snag in the bushes and it has to be quiet and no rattling parts
if ATR make a complete upper in a different caliber for larger game I will get one as well hopefully we will see 6.5 Grendel
