The last two batches of Marlin bolt-action XT-22's I inspected were up to 1990's snuff, as they say
the recent 60's & 795's are better than the 2005-2010 CT guns, when Marlin started having QC issues after they announced the sale of Marlin...
grumpy employees don't make quality guns...
All in all, Improvement is being seen, and since they're still learning on the job in KY & NY plants...
expect to Inspect anything you get carefully...
given the way MFR's in every field are pushing stuff out & letting customers QC it to save money,
you'd wanna do that anyway...no matter who makes what...
Preference...I'd still grab an older Marlin from a pawn shop/yard sale/etc...pre-2005 in the least...
If I were to buy a new Marlin, it would be Carefully Inspected for the known issues...At The Store...before it came home!!
At least the 2012's solved the Out-Of-Spec 60/795 Accessory Rail issue that's plagued Marlins since 2005...
Occasional Rough Bolt issues still exist, but 30 minutes on a polishing wheel resolves that...whatcha expect for $150??
DIP makes the perfect adjustable Trigger Assembly for them as well...definitely worthwhile!!
that's pretty much all the 60/795's need, other than a scope or Techsights upgrade
As far as the XT22's...I'm not fond of the new plastic stock, its better than the pre-2012 one...but its still plastic.
My first move would be to snag a Boyd's laminate of some sort & pillar bed it in

If one keeps the OEM plastic stock...best bet is to pillar bed it...its inexpensive and works WONDERS!!
