    Purchased September 11th 2019 and arrived roughly 5 weeks later. They are extremely backlogged due to the current sale prices.

    This is a very nice piece. Handguard is surprisingly light, and to anyone concerned about how it feels in the hand- remarkably nicer than you'd expect. Everything is well machined and fits very nicely on my PSA lower.

    There are two downsides to this upper
    1. There is no front iron sight mounting solution. Optic only. I attempted to contact customer support to ask if a shorter handguard could be exchanged before shipping and received no response.
    2. The barrel is redonkulously huge. It looks like it belongs on a .450 bushmaster. It almost looks like an unmachined blank. It's not quite a bull barrel, but more than an HBAR.

    For the sale price, this is more than a fair deal. The quality is remarkable and the styling is impressive. But- I wish I had a choice in barrel profile, and I would have preferred to have it shipped with a shorter handguard so I could tap a front sight to the barrel. Lack of support response is a non-factor due to the backlog they're currently under.
