I'm very interested in an XT-22TSR with the tube fed magazine.
I just got back from shooting my XT-22 for the first time, and I had a blast. Here's a quick review:
Ergonomics/Feel:Very natural in my hands; holding it just feels 'right'. The mag release, safety, and bolt are all well-located, so you can actuate them without moving your hands much or at all.
Trigger:Super smooth, right off the bat.
Sights:I was shooting at 10 yards to get a feel for the weapon. After a little while I really had the hang of it. I don't have a ton of experience with firearms (yet), but I was surprised how accurately I could shoot. I much prefer these sights to the stock 10/22 sights.
Bolt:A little bit tight at first, but very smooth by the time I left.
Magazine/Feed:I have the 7-round magazine (not the tubular you're looking for, MSP). Good design, fed flawlessly.
Fit and Finish:I have the plain jane wood stock, but it's a thing of beauty. Much nicer wood than my 10/22. Marlin puts out a product that looks as good as it functions.
Overall Impression/Recommendation:As I mentioned, I don't have a lot of experience with firearms, so I can't compare to other bolt action 22s. However, objectively, I can't imagine another firearm performing better than this. Time will tell how it holds up, but I have a feeling I'll be passing this on to my kids or grandkids one day. Two thumbs up.
