Frequently Asked Questions
Will the MBA-1 kit work with my existing AR-15 lower receiver?
Yes. The MBA-1 Buttstock Kit is designed as a complete assembly that installs directly onto any standard AR-15 or AR-10 lower receiver. The included A2 rifle-length buffer tube, recoil spring, and all necessary hardware mean you have everything required for a straightforward drop-in installation with no additional parts needed.
Can left-handed shooters use this stock comfortably?
Absolutely. The MBA-1 is fully ambidextrous. The cheek piece comes pre-installed on the right side for right-handed shooters, but it can be easily repositioned to the left side for left-handed use. Combined with the multi-directional cheek piece adjustment, it provides a comfortable, consistent cheek weld for shooters on either side.
Is the MBA-1 a fixed or collapsible stock, and does it require a fixed stock lower?
The MBA-1 is a fixed stock — it does not collapse or fold. It mounts to a rifle-length A2 buffer tube (included in the kit), which means it pairs with any standard AR-15 or AR-10 lower receiver. Because it is a fixed stock with a rifle-length tube, it is an excellent compliance option for states or configurations that restrict adjustable or folding stocks. Length of pull is still customizable via the integrated thumbscrew adjustment.
