    Reliability of the AR-7 is highly dependent on the condition of the magazine and on the ammunition used, perhaps more so than with other models of semi-automatic .22 caliber rifles. The feed ramp is part of the magazine and subject to damage from mishandling. Flat-nosed bullets tend to jam on the edge of the chamber of the barrel. The transition of cartridge from magazine to barrel can be smoothed by minor beveling of the chamber of the barrel, by using round-nosed as opposed to flat-nosed bullets and by paying attention to condition of the feed lips and feed ramp of the magazine. Later production magazines include an external wire spring to align the cartridge; earlier magazines used two pinch marks at the top of the magazine body, which could become worn over time.

    All iterations of the AR-7 from the Armalite to the Henry use bolt and dual recoil springs that are heavy compared to most other .22 semiautomatics. The AR-7 requires high velocity ammunition for reliable functioning. The manufacturer recommends use of 40 grain round nose bullets in high velocity loadings. It is still possible to manually load a single round into the firing chamber, allowing use of flat nosed bullets or low velocity or subsonic ammunition.

    The barrel takedown nut tends to loosen after firing and may need hand tightening to maintain both accuracy and reliability.

    Since Charter Arms sold the design and rights to Henry Repeating Arms in 1980, the Henry AR-7 has regained a reputation for reliability.[citation needed]

    With the Golden Boy, from these forum comments even the simpler lever action does apparently present occasional feeding problems with short/half stroke or slow cycling.  Henry's customer service response is also praised.
