The RETAY USA Masai Mara is a 12 gauge semi-automatic shotgun with a 3.5-inch chamber, inertia-driven action, and natural camouflage finish. The RTS (Retay Trigger System) is a distinguishing feature -- it allows adjustment of trigger pull weight, which isn't common at this price point. At 7.40 lbs with a 26-inch barrel, it's in a reasonable weight range for a 3.5-inch 12 gauge.

Detailed Features 

 
The inertia-driven action is mechanically simpler than gas-operated designs -- fewer moving parts and less cleaning required. The 3.5-inch chamber opens up magnum waterfowl and turkey loads that won't run in a 3-inch gun. Truglo fiber optic front sight improves low-light target acquisition. Fixed stock with swivel studs is ready for a sling straight from the box. The crossbolt safety is in the standard crossbolt position.

The Masai Mara Camo gets consistent marks for offering the RTS adjustable trigger system at a competitive price -- that feature typically shows up on more expensive guns. Users mention the camo finish blending well in hunting environments.

Performance feedback is generally positive: the inertia system cycles different load types reliably without fussing with gas ports. The fiber optic sights are called out as a practical plus for low-light use. Ergonomics and comfort over extended shooting sessions come up frequently in positive feedback.

On the downside, some users note the gun runs heavier than they expected. Initial learning curve with adjustments is mentioned by newer semi-auto shooters. Aftermarket accessory availability is limited compared to Beretta A400 or Browning Maxus platforms, which matters to buyers who like to customize. Long-term durability under hard use is an open question for some, though most report solid build quality day-to-day. Overall the Masai Mara positions well for hunters who want a 3.5-inch semi-auto with an adjustable trigger without spending top dollar.
