ACR Specs Thread

I’m proposing that we make a sticky thread of the ACR specs TO BE DETERMINED AT THE SHOT SHOW. We’ve all heard, read, seen, talked to this person, that person this magazine etc. that has given us preliminary specs. The fact is we will not factually know this till shot (and dang hopefully not after). I would like the sticky to be strictly factual, and for questions, and void of complaints and comments. A quick go to for everyone, since I’m pretty sure that every individual legally qualified to by a rifle wants this thing. Adding pics will be awesome!!

Here’s a start of the info I think we’ll want to know:

Last Question: When is the Massoud launching?:D

Looking around here and there, checked the Bushmaster acr site, but can't find the actual weight of it. I am hearing some think it is to heavy but I cant find the weight, and read that the remington version is listed as lighter. Any help? Thanks

bushmaster stats 8.2 lbs, but remington says 7 lbs, dunno why theres a large difference like that
