Myself and a bunch of guys from work(custom bearing machine shop) order ten of these from quinten-laser and machined the fire control pockets ourselves on the cnc mill and they were ready for anodize. I will post a pic with the anodize. All the blue print info is out there for any do it yourselfers.

Go to http://quentin-laser.com/store/index.php?cPath=27. For 100$ all you have to do is machine out the trigger pocket and pin holes then anodize the rest is done. They work amazing and do not have to be serialized I you build them yourself for yourself

Also they are billet aluminum not cast

Man thats cool. I was not aware that anything like this even existed. I am also a machinist and it would be so easy to finish these. How is the quality of the lower? Is the same or better quality as the normal run of the mill lower? I might order a few just as a project but for the long run the extra work isn't worth it when I can buy a 100% done lower for the same price from psa. Unless the quality is better then its worth it.
I feel that because they are billet aluminum the quality is definitely better. The mag well is already cut and mags fit great. Depending on how well you machine the fire control pocket will make or break the project. I used a cnc haas mill and knocked ten out if a few hours. I will never buy another lower from an ffl again because I legally finish my own. No paper trail. I would at least try one and see if you like it and hopefully you will feel the same. Good luck

I think I will all the cnc we have are either haas or mori I personally like the mori more but haas doesn't really bother me. Do you still have the program you wrote for it?

I do have it on mastercam but not sure if it is still in the haas

You don't have to but unless you have a digital readout Cnc would be the most accurate

What is PSA I am new to the forum and looking to build an ar
Do you have to use a cnc?
I wouldn't think so but if you not a skilled manual op. Then it might be kinda tough

Psa is palmetto state armory. They have insanely great prices on everything they manufacture. To the point it is getting hard to get normally let alone with this panic of a ban talk. I'm waiting to finish putting my ar together until after this all dies down and the prices go back to normal. You can get a stripped lower for $100. Plus shipping and transfer fees. But if you could take a look and see if you still have a copy of the program laying around I sure would appreciate it. Obviously you know it would save me some time and headache. I'm not very good with mastercam yet but I can program at the machine. We both know that would take a while.

Thanks and I would like the program also if you have it

I will see what I can dig up at work(that's where the mastercam is)and get some copies

Cool I appreciate it. It would save a bunch of time.
If you look around you can find 80% lowers that have had the trigger pocket already cut. Just need the pins drilled and a few other small things done.
And I do like PSA. They have great prices and if you get a chance to ever go in their store that is off Farrow road do so. The staff that is in there is knowledgeable and nice. They stay busy though.

I go in there when I can't get ahold of something I need. I'm only about an hour away. They usually have stuff in the store that is sold out online.
I love that store. I hate that I had to PCS here to Oklahoma Ft Sill. I did go in there right before I made the trip out here.

And wanted to add that some one messaged me about some lowers that had the fire control pocket milled out and no company sells them any more! The only ones I can find is the ones that needed that FC milled out. That sucks, but I should of bought a few of them a year and a half ago when I came across them. :( Just wanted to put that out before I lead any one else astray.
