Walmart in Newnan is selling the bushmaster m4a3 as you all know now but also they are selling the sig m400, I don't know much about ars but they are so very similar, both same price but which one would you guys pick as a better rifle?

Both rifles are very similar. The Sig however has a 1:7 rifling and the Bushmaster has a 1:9 rifling. I like the 1:7 better because it stabilizes heavier grain projectiles better. It is just more versatile. Also I am really just not a fan of Bushmaster.....
Sig wins hands down in my book.

The sig looks nice. All the reviews ive seen online were good. Im really proud of walmart. They are getting me all misty-eyed.
1:7 twist wins. Being able to stabilize an 80+ grain bullet really makes a difference in the effectiveness of the 223/5.56 round. It not only improves stopping power, it extends the effective range.

Lady at counter said it was same price as bushmaster almost $900. She told me they have the sig m400 but it's not on display. I asked if they have sold a lot of the bushmasters and she says they haven't sold the first one(Newnan loc). I was super surprised, I figured many people would be buying the heck out of them. Bushmaster website has msrp of over $1200 for the m4a3 which is the model at Wally.
Walmart isnt your first choice for purchasing AR's
That is probably why its still there.

I have some 75 grain Hornady bullets, I've had them for several years. My 1/8 and 1/9 shoot em' fine. I just don't ever shoot much of anything over 62-64 grains.
If 1/7 is so great, why doesn't everyone use it. It certainly cost no more to make a 1/7 barrel than it does a 1/9 , 1/12 or any other rate of twist.
The 1/9 works great for 40 grain varmint bullets and everything else I shoot in .223. If I want to shoot anything that a 1/9 won't stabilize, I'll shoot another caliber. I don't get the fascination with 1/7 barrels.

A 1/7 is to fast for the lighter bullets. It will cause a 30 to 40 to plain. This and the fact that there are a lot of 1/9 and slower barrels out there is why more people don't use the 1/7. The faster twists have been developed as people want to get more range out of this round. I also use a 1/9 and 75 is the heaviest it will stabilize. I can get 1000 yards supersonic out of it....barely. The next one I get will be a 1/7 or even a 1/6.5 so I can use the 80 and 90 for max range.
