3 Crosman Benjamin 392s of 2026 For Action And Caliber Fit

Oct 9, 2026 12:36 PM

Shooters routinely overlook that shared legacy designs rarely share interchangeable hardware, especially when automated storefronts lump mismatched action types and calibers together. Ordering without checking the specific action often means unboxing an air rifle that demands disposable gas cartridges instead of reliable manual compression, or receiving rotary magazines that cannot physically fit a single-shot pellet tray. Combine that with the headache of accidentally ordering .177 clips for a dedicated .22 barrel, and the result is bench frustration, useless accessories, and avoidable return shipments.

Target practice and backyard pest control run smoothly once every component aligns perfectly with how you intend to shoot. Getting the right configuration simply requires checking three mechanical details before checkout: confirming the power source between standalone pump mechanics and cartridge-driven actions, matching the bore size directly to your preferred pellet caliber, and verifying whether the breech accepts rotary clips or single-load ammo. Here is how each option stacks up so you can match the right action and caliber to your setup without second-guessing.

How does the Crosman 1077 RepeatAir differ in operation from a multi-pump rifle like the Benjamin 392S?

The Crosman 1077 RepeatAir is a semi-automatic, CO2-powered .177-caliber pellet air gun that runs on 12-gram CO2 cartridges rather than manual variable pumping. Traditional multi-pump rifles require hand pumping before each shot, whereas the 1077 allows rapid semi-automatic fire without manual pumping between rounds. If you want fast plinking without pumping effort, a semi-automatic CO2 repeater provides a completely different experience. You can explore our guide to the tactical air rifle styles to see how repeater mechanisms compare for target work.

Does the Benjamin RC7710 magazine work with standard multi-pump rifles?

No. The Benjamin RC7710 is an auto-indexing 10-shot pellet magazine engineered specifically for .177-caliber Benjamin Marauder and Armada platforms. It does not fit into variable-pump air rifle breeches or traditional single-shot loading channels. Pre-charged pneumatic rifles built for this magazine feature a dedicated receiver slot that standard pump guns lack. Confirm your rifle model matches the Marauder or Armada specification before ordering rotary magazines.

What ammunition do the Crosman 1077 and Benjamin RC7710 use?

Both the Crosman 1077 RepeatAir and the Benjamin RC7710 magazine accept only .177-caliber pellets. Neither product supports .22-caliber pellets or steel BBs. Feeding steel BBs into a rifled pellet barrel can damage the bore and cause feeding jams in rotary mechanisms. Always match the caliber stamping on your rifle receiver directly to your pellet tin.

Can the Crosman DSFAM spare magazine fit Crosman pellet rifles?

No. The Crosman DSFAM is a drop-down style magazine designed for 25-round steel BB capacity, and it does not load lead pellets. The manufacturer lists compatibility exclusively for the DSBR and CFAR1B platforms. It will not latch into the Crosman 1077 or standard Benjamin bolt breeches. If you want rapid-fire BB setups instead of pellet target rifles, check our overview of the CO2 BB gun models for proper receiver matching.

What are the dimensions and specifications of the Crosman DSFAM magazine?

The Crosman DSFAM magazine weighs 1 pound and measures 8.75 inches long, 3.25 inches wide, and 1.12 inches high. It carries model number DSFAM and holds 25 steel BBs, which are not included with the magazine. This unit is built in a single-pack configuration with a multi-color exterior to match compatible receiver wells.

How do you verify magazine and part compatibility across Crosman and Benjamin models?

Check the exact part number and rifle compatibility list provided on the product packaging. For example, the Benjamin RC7710 explicitly lists compatibility with Marauder and Armada models, while the DSFAM specifies the DSBR and CFAR1B. Crosman and Benjamin produce multiple distinct action types, so variable pump, CO2 semi-automatic, and pre-charged pneumatic parts rarely interchange.
