Nope, I've never touched one. And the 3Gun barrel is anything but a heavy profile barrel so you should be fine with it. I've got one under a Centurion Arms CMR which is one of the lowest profile handguards currently available. In fact, the CMR is so low profile, most gas blocks don't work with it without grinding them down though the one that comes with the 3Gun barrel works.

what is the minimum length hand rail I would need to cover the gas block on that barrel?

A 12" would leave about a quarter inch of gas block exposed.

A 12" will leave almost the entire gas block exposed. The ODIN 3 Gun barrel uses an intermediate length gas system so it's just a tad shorter.

I could do some shameless self-promotion

Finally placed what should be my final order with ya... for this build. That just about finishes it up..

 

 

Some sneak peaks. Should be about week until she's ready.

WMD bcg...i'm jealous.  looking to grab one for my ongoing build - i've heard nothing but good things about them.

Yea, I wanna pick up a second for my other AR.

 

Felt pretty slippery right out of the box.

Hey PX, with the luth, what rings do you suggest for a scope. Mid or high profile?

Depends on three things.  Scope size, average target distance, check weld.

T Bill makes a good point. I use ADM mounts and have yet to encounter a situation on an AR where their mount wasn't perfect.

4-10x40, tube is 1", 100 yards, adjustable cheek weld on the stock. I have low profile rings now and there not going to work.

I have one of these with a 5-15x40 on a .308 AR: http://www.americandefensemanufacturing.com/view/product/188/

I ordered some cheap rings to test height with. Once I figure it out  I will probably go with another Larue mount. Thanks for the help through out this build. Just waiting on rings, rail section, and bipod mount to complete it. All are on the way, pictures coming soon.

Is it finished? Pics please?

I'm getting ready to go to the range so I should have pics up by the end of the day.

Very cool. Have fun.

 

Didn't get any pictures today, no sun. But here's one from packing up last night.

It came together nice, I like it.

 

What model S&W?  I've got a 3913TSW, yours looks similar but maybe a slightly larger frame.

4006. Shot it for the first time today. Very nice for 12 years old.

 

Thank you. I will be posting better pictures if we get a sunny day any time soon.
