I've been considering building a .308 AR. I would like to do a lightweight carbine. If I decide to go through with this, I think I want to use one of the CMMG lowers that takes G3 mags, because I already have plenty of those and not having to drop $200 on a combat load of new mags would be preferable. I've handled the Bushmaster ORC .308, and I like the weight. But I like the MOE .308 they do better because it has an FSB. They say it only weighs about 7 lbs, which is where I want this to be at or less, otherwise I've got other rifles that fit the bill.  

So far, the best idea I've come up with is to get the CMMG lower, and then an upper from Bushmaster. Unfortunately, they don't have uppers, or barrels listed separately yet.

Any other ideas?

So basically, here are my perimeters for a carbine:

1)It needs to weigh 7lbs or less empty.
2)It needs to use G3 or possibly FAL mags
3)I want it to have a regular FSB and a forward assist on the upper
4)I don't want it to cost me the rights to my first born (i.e. less than $1500 total)
5) I would prefer to build it myself rather than buy a rifle

Wrong forum. You want AR Variants. This is for ArmaLite products.

oops...

That is a tall, if not impossible order.  Let us know how it works out.  I am interested to see what parts go into it.

That's the hard part.

I see basic DPMS 16" rifles on Gunbroker as low as $800, a possible starting point.

Don't the CMMG G3 lowers only accept DPMS .308 uppers?  I plan on building an AR ,308 also and really like the G3 magazine option.

CMMG G3 lower with a DPMS A4-style upper.  The rest is just "buy the lightest thing you can find"



 

hmmm well I guess we'll just have to see what we can come up with
