AR-15 Build

I blame you guys mostly. I'd look at a picture of a sexy AR and keep repeating to myself, "Thats nice, but I don't need one." Well, I could only take so much. Thanks a lot guys...:mad:

I would like to hope I have the skills to build one from scratch, so thats what I'm doing. I figure if I do the research and do it myself, when something goes wrong I won't need a gunsmith on speed dial.

Starting with an M&P 15 lower to support the locals. DPMS lower kit and Daniel Defense upper are the first things to show up in the mail. A lot of the items I want are back-ordered so this will take longer than expected. Good thing I have time.

So my first problem has already arisen. I can't find a Daniel Defense barrel with a 1:9 twist, only 1:7. I've read that a 1:9 is desirable, but will I make a bad decision getting a 1:7? FYI, I won't be shooting any tracer rounds or going full auto.

I can't really help you but that is a very nice Lower. I am doing a build for the Mrs. She doesn't know yet.

1:7 might be problematic with lower grain, less than 55, varmint rounds...what barrel length are you thinking of? What types of shooting are you planning on...plinking, longer range 200+, coyotes?

I was thinking between plinking and yotes, no long range for this one.

1:9 would be the most versatile for those situations giving you acceptable performance across a range of bullet weights from 40-69ish. Anything lighter or heavier may have self-destruct or understabilization issues, respectively. A 1:7 will help on the heavy end of the scale but would most likely take the 40gr option away, either will handle the M193 55gr standard.

Step one complete.

The qquality of the machining on the M&P's is awesome. Why don't you check out some of the other barrel makers other than DD? There are a ton of options out there.

I'm open to suggestions. I was just going with DD because of the quality. I can't own one of their rifles, but I can build one as long as the lower is MA compliant. http://www.aks-glos.org.uk/cms/media...20confused.bmp

I am pretty sure J and T sells individual barrels. They only use Wilson Combat and ER Shaw. Nice stuff at an inexpensive price. You can download their catalog online
