Ordered while there was a small sale. I got the lower almost a month later, looked up the shop on google maps. On google maps I saw their high end CNC machines and they have a good small scale production.
When I got the lower I instantly felt how light it was compared to some other lowers. It appeared that the Cerakote was done in one layer and missed the buffer tube threads, I did ask for custom in FDE. Also the buffer tube threads seem like at the end they are slightly off but I believe it could be fixed easily.
The lower has the circle cut in the grip and is nicely machined. Really a great looking lower, I asked for 7075 but not sure if it was in 6061. Not yet built but hope to use on LMT upper. Not sure if exactly what their return/exchange policy is, but overall I am very pleased with the lower.
I don’t have their other Lowers but if I was going to buy another one, I probably would do the full or light skeleton again considering .308 is very heavy.
