My RRA stainless carbine upper has no markings on it. Even under the handguards there is nothing. Wanted to find out how to tell the twist rate of the barrel. Anyone have any ideas? Iheard of useing a cleaning rod with patch to see how many twists it has as it goes in the barrel.
HELP PLEASE!!

Tight patch on cleaning rod inserted in to barrel. Mark a point 12" down rod and put a piece of masking tape. Mark top of masking tape with tic mark. Push rod in 12" and count tic marks revolutions.

i use a sligt mod of above, tight patch on rod, black sharpie marks on rod every inch, in a straight line up the rod, push in slowly, count how many inches in for one full revolution. slightly quicker than above b/c no math involved.

You could bring it over to my house and I'll take a look at it. Of course the fee would be that you either give me the upper or the money equivalent in ammo. Maybe you could contact RRA? Hope this helps. Take care my friend. And welcome to ARFCOM.

Thanks for the welcome. Its the first one I have gotten. You know 38 posts and all... ( kinda makes me a little weepy eyed) If I bring it to your house I will need your first two born in trade for my RRA. And also 200.00 in cash.I will try the RRA phone call tomorrow. Thanks.
