Happy to say that I got my Quentin Defense receivers last week! I ordered two AR15ChatterBox billet lower receivers and a single QD billet upper receiver. I'm in the process of building one AR-15 now (CB0029) and saving the other lower (CB0030) for a future build. I didn't want to get legislated out of the chance to get another lower in the future.

Quentin Defense stripped billet lower receiver:


Quentin Defense billet upper:


Both of them together:


My plans are to start assembling the lower this weekend. I don't have the barrel, handrail or sights yet, so I'm not really in a hurry.

Thanks to Jason and all the Quentin Defense guys! They did a great job on all my parts and they are just like I wanted them... They are almost too pretty to shoot... Almost!!!

Thought I'd put up a list of the parts I used to build my AR-15. I always liked to look through everyone elses parts list when I was putting mine together... Also a couple of pictures, since it's completed and shooting now!

Awesome! I love that upper.

Thanks, guys...

My plan is to build a Mark 12 Special Purpose Rifle... It's not going to be absolutely identical to a genuine Mark 12... I'm going to get different hand rails and a few other things... but it should be functionally similar to a Mk 12.

I'm going to use this rifle mostly for target shooting... There's a 12 to 100 yard range pretty close to me that has reasonable prices and a 200 yard range within 40 miles... I'm buying pretty good parts for it because I plan to shoot the heck out of it.

I have most of the parts and tools to build the lower and the tools to build the upper... I am planning to use the stock DD LPK trigger because I'm going to spend the money I was going to use on a better trigger on a better barrel. I can swap the trigger out later, while I'm not so likely to switch barrels after the build...

My plans for a barrel are not very original... I really like the 18" Noveske Stainless Steel Barrel that Bones got. It has pretty much everything I am looking for in a Mk 12 barrel... 1:7 twist... Intermediate gas system... comes with a low profile gas block... Only down side is that it is expensive... Hope to order it in a week or so...

Still need a flash suppressor... rails... and sights...

Props on the barrel choice.

Assembled my QD Lower Receiver and thought I would put up a few pictures... I am very happy with everything so far... The billet QD receivers are truly a work or art, but somewhere along the assembly they have turned into a rifle that I can't wait to start shooting!

I "borrowed" Rusty's idea about threading the takedown pin hole and putting a set screw in it to hold the spring and detent. It worked well except that it made the takedown pin too hard to push out. I suspect the right answer is to trim the takedown pin spring a bit, but I didn't think of it before I assembled the buttstock.


Here are a couple of pictures of the assembled lower receiver...


The upper receiver is just installed for looks... I'm still waiting for the barrel, flash hider, and hand rail...


The trickiest thing for me so far has been the trigger installation. I used a DD LPK with a standard trigger.. getting all the springs and levers took a while... I know it's not difficult for you guys, but I wanted to make sure I got it right of course.

Looks great!
Yep, next time you take it down, trim some coils off of the spring.

Great job! I had the same issues putting together my first lower. I think I psyched myself out that it was going to be more difficult than I thought. When I finished, I kind if looked at it and muttered "that was it?".

I've only put 4 together I think, and the last one was the only one that a spring didn't shoot across the room and lead to a 2 hour search.

Of course my last lpk had extra springs in it so it wouldn't have mattered. When the first 3 lowers' springs shot across the room I didn't have any spares. I did drop one and found it in my chair.
