Great Deal on Spikes Tactical Gen 1 Multi-Cal. Stripped Lower Receivers

We currently have a really great deal on these Spikes Tactical Generation 1 Multi-Cal. Stripped Lower Receivers. Spike’s changed the way they do their markings, and we were able to get a good price 1st generation models.
Here is the skinny:
New Spikes Tactical Generation 1 multi-caliber AR15 stripped lower receivers. This is the basis for any top quality rifle. Machined from a 7075 T6 Mil-Spec Forging. Mil-Spec Type III Hardcoat Anodized finish. Low Shelf for use with RDIAS. Lazer engraved markings. Bullet Pictogram markings in the Safe/Semi/Auto positions. While supplies last.
So what is the difference between these, and the current model? Good question, and a popular one.
The difference is the depth of the markings. These were lazer engraved so the markings are not as deep as the Gen 2.
There is no other difference.
Generation 1:

Generation 2:

These lowers are proving to be very popular. We still have a few left, and have the final shipment showing up early next week.
