I bought a SPR94 ( 22lr over 410) "A Remington "subsidiary at the time"
I sent it back to Spartan arms for work on the rough 22 chamber, extractor, very difficult cocking and absolutely unusable trigger--it grabs several times before firing.
It took over 6 weeks and when I got it back the cocking lever was considerably easier, the 22lr chamber and extractor was corrected.
However "they do not do trigger jobs" as I was told several weeks after I received it back.
I still have a firearm which is not usable for any kind of a aimed shot.
SO, if you choose to purchase one of these firearms (AND I WOULD NEVER DO IT AGAIN) be forewarned that it will require some extensive work at your own expense.
