PRODUCT DETAILS

TECH SPECS:

The KUNA .40 S&W Pistol with Strike Industries FSA folding brace combines a compact configuration with a roller-delayed operating system designed to reduce felt recoil and improve shooting control. Built with a monolithic aluminum upper receiver and an injection-molded, glass-filled polymer lower receiver, the KUNA balances durable construction with a streamlined design.

This model features a 6-inch cold radial hammer-forged barrel with a Melonite® finish, a 9/16x24 thread pattern, and a multi-port muzzle brake. Hybrid flip-up sights provide adaptable sighting options, while the integral M-LOK® handguard supports compatible accessories. The reversible, non-reciprocating charging handle and ambidextrous safety switch offer convenient controls for different shooting preferences.

The included Strike Industries FSA folding brace attaches to the Picatinny receiver end plate and folds for compact storage. The KUNA also features a flat aluminum trigger, an AR-pattern grip with adaptive grip texture, and two 30-round translucent magazines with metal feed lips, as specified in the supplied product overview.

What is the difference between a bolt-action rifle and a semi-automatic rifle? Answers (1)

Proven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.
