So we have a less expensive alternative for the official aluminum MCR® adapter. $145.99 is the price of the standard adapter, ours is only $35. So that is over $110 savings. A much better price for an item that at times can get easily lost. Our magazine adapter plugs directly into the standard magazine well of AR15/M16/M4. Then with the adapter in place it allows the mounting of linked ammo containers directly to the rifle. Made with Steel Reinforced Rigid Carbon Fiber Polycarbonate Lifetime guarantee Great backup if you already have the standard adapter, but would like to have a backup. Save over $110 for the same feature and capability https://www.cryostructure.com/product/mcr-magazine-adapter/

So we have a new 3rd hole jig that works on BOTH sides of the lower. Past ones only worked on one side which could cause problems and you would need a drill press to accurately guide the pin & it was the only complaint with that past with this type of jig . With ours you just need a standard hand drill to drill both sides. This is a brand new design that has never been made before. Hardened drill bushings for a lifetime of accurate surface. Aluminum with hardened pressed fit steel bushings and pins. Just contact us, but we will have you send us a copy of your FFL & SOT. We will only ship to the addresses on the FFL& SOT license. $50 each with $8.95 flat shipping. https://www.cryostructure.com/product/sot-micro-jigs/

Are they in somewhat high demand?

I was looking for manufacture precision bullets using a screw machine for the US market at the best value price for the precision. I was wondering at what prices and quantity that people would be looking for? I can probably beat the prices on all solids for the same materials in the country, if I had a good baseline product. I'm looking for advice on what to make and if anyone would be interested at certain price levels. Thanks ~ Paul
