Default DSArms unfinished AR15 blanks (0% Lower Receiver)

Anyone ever bought these unfinished blanks from DSArms? (0% Lower Receiver)

http://www.dsarms.com/prodinfo.asp?number=1001

Thinking about picking a couple up to try and do a project.

Any thoughts?

I've had my eye on these for some time. Getting from 0 to 100% is not trivial though.
80% is doable with a drill press, but not 0%

I've finished both 0% and 80% lowers. Spend the money on the 80%, you'll be money a head big time. The DSA lowers are nice, but you'd have at least 7different setups/fixturing positions to finish one. Especially if you don't have access to a mill it can be pretty time consuming.

Once set up and zeroed I can finish an 80% in a bout 15 mins. on my cnc machine with only one set up. The DSA take me the better part of a day with all the fixturing and re-zeroing that has to be done.

Edit: Also don't forget the price of tooling, most 80% have the buffer tapped, the 0% do not. Unless you can borrow one that tap alone ranges from $70-100.

Isn't this a 0% lower?



To me that one looks like a 20% or more lower.

I would only do an 0% if I had time, the tooling, and a cnc mill already. Like you said getting the 80%- 100% isn't that hard and is doable on a drill press.

There are a lot of steps to complete the 0%- 80%

I agree with a zero lower you would need a milling machine and a working knowledge of the machine, Buy an 80% lower and save yourself the headaches

Thank for the responses... decisions decision... better part of a day, sounds like a fun project but i don't know that i have an entire day or two or CNC mill time to do it.

Maybe i should go 80%. Anyone know where i can pick some up?

Took me more than a day in a CNC mill (programming and setting up takes time). Hand filing the magwell takes time. Buying cutting tools costs money. Don't do a 0% unless you can set up and run a milling machine. If your time is worth as much money as mine you'll save lots of $$$ doing an 80%.
