The Quantum Series mil-spec billet lower receiver features our patented Presslock™ design and technology, which guarantees a tight, rattle-free fitment with any mil-spec upper receiver, and also reduces wear by eliminating carrier tilt. To achieve this, a small linear cavity is precision-machined into the front of the receiver just behind the pivot pin, and a replaceable panel of aerospace-grade composite is inserted into the cavity. This composite sits slightly higher than the top of lower receiver and consistently applies six pounds of upward pressure onto the front of the the upper receiver. This causes the front of the upper receiver to lift and the back of the upper receiver to fall, just enough to remove tilt and cause the upper receiver to sit firmly in place.
If you’re looking to start or finish your premium AR-15 build, this is the receiver that belongs in your hands.

THOMAS M SPEZESKI –
Just as advertised. Great innovation, design, aesthetically pleasing, and reinforced in all the right places. With the linear compression pads, the upper and lower have no wiggle. None. Customer service is second to none. I had a few questions, got a prompt reply and spoke with a tech who happened to be in on a Saturday! Will buy from Blackout again.

Great lower receiver, very tight between lower receiver and upper receiver from another maker. Didn’t even have to use the linear ion pad like I thought. Just completed my build and will take it to the range this week for testing.

Hello,
I had emailed asking about this previously but I wanted to put this out there for suggestion and feedback. It would be awesome if the Quantum DTL lower receiver with the engraved crossout logo be offered for sale as well. My 2 cents is that I prefer the engraved logo instead of the cutout logo on the Mark 2 receiver.

Thanks for your feedback. We do plan to offer the engraved receiver for individual sale in the future.

Question
Daryl –
Is this lower receiver compatible with the complete DTL upper?

Blackout Defense –
Yes. Our lower receiver is mil-spec and is compatible with any mil-spec upper. Likewise, our upper receiver is mil-spec and although the DTL system is proprietary, the complete upper is still compatible with any mil-spec lower.

Hi – Is your QM2 lower compatible with Aeroknox’s AX 15 upper and handguard? Thanks!

Blackout Defense –
The Aeroknox AX 15 upper is advertised as mil-spec. It therefore should be compatible with our lower receiver.
