The 10/22 NEEDS more aftermarket parts than the Marlin.
Never buy a 10/22, just buy all the parts and make your own, which will be better than anything Ruger ever put out.
Or, get a Marlin 795 for $129 (or less on sale) at your local sporting goods store.
Marlin has a $25 rebate as well on their website.
Marlin accessories also tend to be MUCh less expensive than Ruger accessories.

Ramline Lockarm stock for a 795 - $14.90

Why pay more for less performance??
Get a 795 and be HAPPY
