From the information I've gathered from the recent post, yes. Please correct if I am wrong, the backpacker 10/22 stock length is ~19" with the Dlask 8" barrel the OAL will be 27".
Close. We make the standard 10/22 barrels in 8 in but the Takedown barrels are 9 in. You need the extra inch on a Takedown in a Backpacker to make it 26.5 inches and thus N/R.
