hi,

What's the deal with the sig mcx in 300 blackout? They are impossible to find.

I have seen a few in 223, but there are no conversion kits available on the sig website. I like the Sig because you can easily change calibers between 223, 300BO and 7.62x39.

I'm getting interested in this caliber because I have a suppressor pending approval.

I know Daniel Defense has a rifle in this caliber, and I'll probably go this way if I can't find a Sig. Any other good manufacturers sell completed rifles ?

The list of companies that sell .300 AAC rifles or completed uppers is quite long, many of the AR manufacturers have the caliber in their line up.

DD
BCM
Noveske
Colt
Barrett
AAC


And a bunch of other lower tier makers. It all depends on how much you want to spend, and what features you need on your rifle.

The .300blk is a great round. You can buy supersonics that have terrific terminal ballistics and you can buy subsonic rounds that are vey quiet when shot suppressed and still have decent ballistics. I too am waiting for my can approval from the BATFE...and waiting....and waitiing.....
