Description
Our new and improved billet AR-9 80% lower is here!
Featuring an updated design with better aesthetics, a new magazine catch and ejector fasteners, our second generation AR-9 80% lower is better than ever. Made from quality billet 6061-T6 aluminum. Compatible with standard AR-15 lower parts kit components, and all 9mm AR uppers.
ONLY compatible with standard 9mm GLOCK® OEM magazines.
- LRBHO (Last Round Bolt Hold Open) – Since our AR-9 lowers do not house an internal linkage for the bolt catch, you’ll need an upper receiver with integrated LRBHO to keep the bolt back on an empty magazine. Double-check your upper’s specs to ensure full functionality.

WILLIAM CULLUM –
Appears to be great quality
Brian Shepherd –
Fast shipping. Looks to be a very high quality lower. Very satisfied
Phillip Olsson –
Part has multiple dimples from rough handling prior to coating process. Also open area of mag release por has many burs left and then coated. Also slopes around grip area didnt mesh will with mogpol grip, had to sand down the grip to get it to sit flush with the lower. Not sure if that plast incident was lowers issue or grips issue. Havent fitted a. Uppto the iten yet, but i have milled the item, fit in jig perfectly. Milled nicley, still need to do an assembly to see what else is noticed. It is a nice piece but i feel some final honing processes had been skipped…
Thomas Greenhaw –
Am on my third lower from your site and am completely satisfied with the first two and have the expectations that the one I just received will perform as described
Joseph Frost –
Excellent service and super fast shipping.I need a new jig and hope to get it soon.Shame that the legislation is muscling in on our American rights and customs.Get in while you still can.
Andrew Hartsfield –
Ultimate home defense weapon. Nice and light, easy to move in tight spaces. Very nice! Probably my favorite AR.
Danny Troy –
This AR-9 lower is the bee’s knees!! Beautiful machine work. Couldn’t be happier. The upper couldn’t have mated up any better. Not a bit of light came through anywhere. Shipping was amazing! I was so happy with 80% Lowers, I had to order a .308 lower. Witch turned out to be another work of art! Not even the Louvre museum is worthy of what 80% Lowers offers. O I can’t forget about the crazy low prices?!!? I’ve ordered paper weigh lowers else where for close to twice as much $$. I’m definitely a repeat and loyal customer from this day forward!!
Mark Luther –
Haven’t got to it yet but if it’s like all the rest of your lowers I know it’s a great product
Peter Tricoche –
