I own a S&w 15-22, it is a fine gun, but i got it from someone that owed me some money for computer work.
I just have a problem with the cash price.
If you are looking on a budget, i would suggest a Mossberg 702tactical or 715 tactical.
I have owned 2, both had the same internal .22 semi rifle inside a polymer shell.
i won't call it plastic because it is more of a glass filled nylon.
The first was a used one with the long funky looking forearm and fixed carry handle.
The handguard was slightly loose fitting on the action, so the front sights would rotate a half a degree or so left or right.
Good for rifle drills out to 50 yards on man sized targets.
But it fed almost everything i shot through it.
the only malfunctions i would credit to the cheap federal bulk ammo, and you could hear the difference in the report of the round and the empty case would be ejected (if it had the power) only a foot from the gun, the others would land several feet away.
Fun gun, but not control wise accurate to an ar-15 (safety, mag release, and charging handle)
The second one i owned had the flat top and removable sights, and the flash hider on the barrel.
Internally, the same gun.
Externally, quality control wise, it was heads and shoulders above the previous one.
Same control locations as the earlier one, but the action was tight into the shell, and much more accurate compared to the other one.
Red dots fit easily, was adjustable in length of pull, fun to shoot, younger shooters like it too.
Detail stripping/cleaning sucked.
15+ screws in the shell, then it is about the same as cleaning say a marlin model 60.
Normally I am a clean gun nut. but decided to see what the 715t would do with minimal cleaning.
No dissassembly, and other than spraying some CLP into the open action, scrubbing with the small end of an m16 brush, spraying with a little compress air, then running a bore snake down the bore and a shot of CLP on the bolt and work the action a few times.
in over 6,000 rounds no problems i could not contribute to cheap ammo.
CCI Minimag, and CCI Tactical ammo it ate like a kid eats m&m's.
Same with Winchester m22, and winchester bulk white box .22.
Remington bulk 325's i could hear the power difference with the bad rounds, same with federal bulk.
Hope this can help you some.
