ADCO, I sent 2 AR10 upper receivers with all parts to have assembled. I did not send the mid length A2 handguards. Now I can not get the handguards on,,,they seem to be almost 1/4 inch too long. I am very confused, never had this problem before. Please help! Thank You!

That was a just a basic assembly order.  I don't remember it.  Some AR10s have longer gas systems. Do yours? Who made the barrels? Do they have FSBs, or gas blocks?  Is there a shoulder on the barrel the gasblock/handguard cap is up against?  Can you post a pic?

The barrels are Ballistic Advantage. Yes they have a shoulder. Yes they have gas blocks. Pictures in next post.
Thank You for the quick responses!

I'd contact the manufacturer of the barrel nut and see what they say.  from the pics the parts look like they are where they are supposed to be. Maybe Something somewhere doesn't seem compatible.  I dont have anything similar on hand that I can measure to check distance from handguard cap to barrel nut teeth.  That the first place you should check.  Maybe the barrels are bad and the shoulder for the gas block is in the wrong place.

Thank You for your help. I checked another and it is 1/4 inch longer, handguards  fit perfect. The good one is a Faxon barrel. My guess is I got screwed with barrel seconds, I will call BA Monday.
