    purchased with 9mm upper

    Posted by Col.451 on Nov 29th 2021

    Excellent quality and am headed to range this week with it. Pricey but you get what you pay for. Fit and finish superb and the shorty upper is exactly what I've waited for.

    No brainer. If you're unsure of this product then you haven't been paying attention. Buy it. If you buy a dedicated lower it most likely won't have last round hold open
