I'm pretty sure your daughter has a nicer AR than 95% of us do. Good job dad.


If you're ever looking to adopt a son in his mid-thirties let me know. We could build a bunch of cool shit together...on your dime of course.

Nice build! Bet yall cant wait to take to the range!

Her first AR is nicer than any AR I’ve ever had

What exactly is an "extended gas system"? Is that like in-between a mid and rifle length gas system?

Yep. It’s longer than a midlength, but shorter than the Noveske Extended Length, which was designed for an 18” barrel. The BRT system uses a proprietary length system, with a specific gas port size, all specifically designed for optimum functioning with a 16” barrel.

That's pretty cool. Is it supposed to mitigate felt recoil better than a mid length?

From Black River Tactical’s website:

The BRT extended length gas system was created to allow optimum performance from 16" barrels. The gas system length controls the timing of the gas cycle and overall gas drive available. Existing gas systems, while functional, don't offer the balance of factors to allow exceptionally smooth cycling with maximum reliability. The BRT design balances these factors to optimize gas system performance under extreme conditions.

Thanks, I guess I could have just googled it.
