Type III Hard Anodized Billet AR-15 80% Lower Receiver - Ambi - Blemished

Calculated at Checkout


Norton Shopping Guarantee

We received permission from the Federal Court to sell this item. State Restrictions apply. READ MORE.


These are AR-15 6061 Type III Hard Anodized Ambidextrous Billet Lowers but there are some visual imperfections that do not meet our standard of quality. Aside from the issues of being off-color or having marks, they are perfectly in mil-spec and functional lower receivers.

Blemished products may include - plating inconsistencies, color variations, scratches, dings or the magwell was re-broached. 

These do not qualify for bulk purchase discounts, due to the fact they are already highly discounted.  The lower replacement plan discount code does not apply to these as well.  

Blemished lowers are a final sale item only.  

With freshly contoured lines, and packed with features, the Ambi 80% AR15 lower isn't just the best looking 80% lower receiver available, it's the most functional as well.

From a right-side bolt release, to multiple adjustment screws to tune the fit and function of your lower to your liking, we've not only given you all the features you want, we've done it at the same weight as our classic lower.
