I have an AAC Tirant 9 on the way from Silencer Shop. Right now you can get one for $399. They'll ship it with one mount of your choice. You can also get the AAC $200 online store credit if you buy before the next year. Then you could buy some more mounts or other stuff. It's a great deal.
What a great promo, can't believe that deal, almost too good to be true...so I ordered one!
I'm pretty pumped to try this sucker out, just need to get the tax stamp started. Thanks for the recommend, I'd have never known about that site/promo otherwise.
