Hi Marcus, I would contact Bud's and see if this is still shipping with no brace or not. Since the ATF has been over ruled, braces are now legal again. It is possible Bud's is shipping with brace once again. 1-859-368-0371 9am-9pm EST Mon-Fri. or use the Blue Chat now button at the bottom right corner 9am to 8pm Mon - Fri
If no brace, it would be very easy to install, but personally, I would not spend this amount of money only to have to purchase my own brace, which is going to an extra $100-150.
Stay safe & have a great day!

yes one can be easily installed

Hi Marcus and welcome. No Sir. This already has the slotted buffer tube and it would literally take 5 seconds to attach an SBA3 Brace : budsgunshop.com/product_info.php/products_id/143779/sb+tactical+sba3x-02-sb+sba3+synthetic+flat+dark+earth+5-position+adjustable+for+ar-platform --------- Cheers and stay safe!
