Big Gun, now as far as 20" vs 16". The 20" T weighs 9.4 lbs, the 16" T weighs 8.6 lbs. They will shoot the same with exception of the 20" having a 100 yard advantage. That .8 lbs is on the nose of the rifle. Remember this rifle is heavy to start with. What few people realize is the shorter barrel whips less, and as a result you can machine it lighter in profile. The 20" has this same advantage over the 24". The primary difference you must look at is velocity, how far you want to shoot. 16",20",24" is 700, 800, 900 yards respectively. So your 400y requirement is well under that. Now these ranges are the transonic barrier so as we have already covered that is not respective of hunting range.

I'll jump in on this part.....LBG, I have a AR-10 A4 CB...(16" barrel), for the most part built to a combat configuration, taking a target at 400 to 500 yards is no problem....so my advice is build what you are looking for or buy it..(my preference) and you can always add a different barrel or buy a different upper down the road if your need changes....
Oh and just for the record....and the rest of the class...
DPMS WILL NOT FIT THE ARMALITE LOWER WITH OUT BEING REAL UGLY...
notice the difference between the two..

Hey Bod

I appreciate the research. I do not have the tools, however I was thinking about purchasing for future use. There is no doubt in my mind that once I build this, I'll want to do another application. Or one of my blood brothers will want to build one. What I have pieced together thus far $I'm looking at $900. I'm thinking maybe I'll hold ff on the Timney because that is a sizeable nut. I can always add later.

Thank you so much! I'm glad there are people outthere that really want to help. I will post up the parts I put together and please tell me what you thnk. Oh, what does the "twist" mean in the barrell? I'm assuming the that's the rifeling? Can I get away with 16" rather than 18" taking into consideration I prob won't shoot over 400yds, and weight?

Rifling twist is the rate of revolutions per inches of travel down the barrel, e.g. a 1 in 12 twist will take 12 inches of travel down the barrel to make one revolution of the bullet. Generally speaking heavier bullets stabilize better at a faster twist rate than lighter bullets, all things being equal. A 1:9 is faster than a 1:10.

As far as your barrel length a 16" should do you just fine. As Bodenjager said, shooting at anything beyond 400 yards is starting to border on the irresponsible, depending on your skills and abilities of your equipment. As I said in an earlier post here you won

That's it BMS, I had it bass ackwards. I don't think the DPMS style will fit on the ArmaLite.

You ever have enough guts to try and touch one off to see it it would really work?

Big Gun,
As for the twist, it does reference the rifling. As for what to use go with the 1/11.25 as it is designed to stabilize a wide range of bullet weights. For hunting you don't want to go to heavy. As a rule of thumb the heavy bullets tend to over penetrate. The 1/10 twist is mostly used by bench rest match shooters to stabilize the heavy 175-185 grain high ballistic coefficient bullets to push the limits. I agree with Ducks last post the 16" will reach well past your hunting range. As far as your blood brothers go, Simper Fi.

That's great. So now I know what's the appropriate twist for my application. We're getting there! Slowly but surely. Thanks Bod..

Here's what I have thus far:

Armalite AR-10 lower receiver stripped $205
AR10 LOWER RECEIVER PARTS KIT W/ NATIONAL MATCH TRIGGER, BLACK $225
AR-10A4 CAR UPPER HALF, BLACK W FORWARD ASSIST $786
762 SASS : M15/AR10 A2 Buttstock assembly Black $42

Total gross: $1,263

Somebody posted the total the other day, I forget who that was, but once again, I do appreciate the research.

What do you guys think? Am I missing anything? I'll worry about glass later on. This is going to take me some time to muster up the funds, unless I start selling some stuff around my house. :laugh:

The first component I'm going to buy is the lower with kit. I'll start there. I honestly like the collapsible stock, but I wasn't able to find one for less then $100. Maybe I'm over looking things? However, the buttstock above seems like it would work better with my application.

LBG, it looks like you have pretty much everything you need...to get started...If I may, you asked my honest opinion...so my friend...here it is...
For all you have there....You could buy a complete A4 for about the same price, minus the Match Trigger...
www.armalite.com/ItemForm.aspx?item=10A4...aa-aea0-49488ec48776
Now the prices are SMRP... My local dealer has two A4s on the shelf for 1369.00, now that is just the first one....
The second, I know you said you are going to use it for hunting and competition so the match trigger will be fine...but quoting some of the Pro's "Match triggers are fine for the range and hunting...but have no place in a combat weapon"....just some food for thought...
I am not trying to be rude or persuasive, you do as you feel...if you want to build it,,,,then build it...just wanted to let you know you could buy one for what you are going to spend on it...and as for the trigger, well that is just me...so my friend...I hope I have been of some help....
I am not knocking anyone who builds their rifles...I just think the first one should be a factory one as to get used to the gun and equipment and what make them work....and the warranty of course, you get a better one a whole rifle rather than parts..

I have to agree with SASS on this one. If your not careful you could ruin an upper without an action block. If you buy a complete rifle you get an accuracy guarantee as well as a warranty.
