The .45acp carbine is in like new condition with less than 100 rounds fired through it. It has a 21lb. recoil spring (stock for the 9mm and .45acp is 11lb). Two 7 round mags included (1911 style mags, they work perfectly in my Springfield 1911A1).
The 9mm I bought from a retired cop so I can't say for sure how many rounds are through it. Doesn't look as perfect as the .45acp carbine, but still in good shape. I have installed a 16.5lb. recoil spring in this one. 10 round mag included. It also accepts S&W full capacity 15 and 20 round pistol mags.
Both carbines have performed 100% for me and are very accurate. These are discontinued from Marlin and are no longer available. They both have deep blued finishes and wood stocks. Both are drilled and tapped for a scope mount. The Camp .45 is $500 and the 9mm is $375. Both prices include shipping to your FFL.
