I’ve been shooting for 7 years and I’m picky about where I buy accessories online. Americans Gun earned my business. The Rock Island Meriva 12 Gauge Pump Action Shotgun with 18.5″ Barrel – Black Finish CR103 arrived in 3 days, packaged well, and fit my G22 without any modification. I put 328 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.

Bought this as part of a larger build project. Americans Gun had the best price by a decent margin and shipping was fast. The Rock Island Meriva 12 Gauge Pump Action Shotgun with 18.5″ Barrel – Black Finish CR103 itself is well-made — OEM-spec fit. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.

Third purchase from this store. Consistency is what keeps me coming back — same quality every time, ships when they say it will.

Product is fine but shipping took 6 days instead of the 3 they estimated. Not a huge deal but worth mentioning.
