I am filling out a form one to build a sbr. I will be getting a 10.5 upper. What is the overall rifle length wth a collapseable stock fully entended?
Thanks

Mine is right at 28" with a slightly longer than average Troy Claymore.

The proper measurement for a Form 1 is stock extended and no muzzle device.  My 10.5 with Magpul CTR is 29"

Measure an AR with a 16" barrel and then subtract 5.5 inches.

Use an existing barrel, SHARPIE, masking tape an STANLEY are good friends  

Figure approx 29 3/4 OAL  (with A2 hider on end)

That works fine, only don't measure the muzzle device if it's for a Form 1.

Should be 28.5-29.75 depending on your choice of stock. My 11.5 came in just shy of 30".

No. There's so many variables to overall length, they have no idea if it's correct or not. They'll approve it. If you get the gun assembled, and it turns out to be different, you can just notify the ATF in writing, although it's not required.
