The truth is, you'll only have to invest a fraction of that to build it yourself...
And even better, because you're building it, it will be 100% custom to how you like it.
In fact, because you'll be only using the parts you want to use to build your rifle, you'll be able improve anything you don't like ...
If you want a better trigger you can do that ...
If you want a stock that fits you better, or the color you want, and the rail style you need, it's all your choice...
If you want better sights, or a certain scope, that's easy too ...
The truth is it's all up to you and it might even save you money.
Look at it this way: many people buy an AR-308 for $2,000 or more.
Then they don't like the stock, so they spend another $70 or or more to get a stock that fits them...
And they don't like the rail, so they upgrade to a free float rail for another $100 to $200...
And they don't like the trigger, so they spend another $150 to $200 upgrading the trigger ...
After just a few upgrades -- they've already spent near $1,000 upgrading a brand-new rifle!
Doesn't it just make sense to simply build the custom rifle you actually want, from the start?
