Ronin (MCU)'s weapons
Hawkeye is seen with two separate recurve bows: the first is seen while he is under Loki's mind control and in the direct aftermath at the Battle of New York. It is a heavily customized Hoyt Buffalo in 'blackout' colors and is capable of folding on itself for easier transport and concealment by way of added hinges located by the tiller adjustment bolts. It also has multiple buttons on the bow's grip which are capable of selecting specific arrowheads stored in his mechanical quiver. A laser sight to assist in targeting can also be found on the riser. The second recurve bow Hawkeye uses is the Hoyt Gamemaster II, seen in his hands during the Avengers' attack on the HYDRA Research Base and War against Ultron. Like the Hoyt Buffalo he used before, the customized Gamemaster II has several selector buttons on the grip so Hawkeye can choose the arrowhead he needs. The bow has a capability to transform into a bo staff which can be used for close quarters combat. The bow was destroyed by Black Panther during the Clash of the Avengers.
Hawkeye's quiver was supplied with a multitude of different arrowheads in the bottom. By dialing up an armament setting from control on his bow, Hawkeye could cause the quiver to affix these special arrowheads. This effectively increased the capabilities from conventional arrows to explosive arrows, a grapple line, and more.
Hawkeye has a number of trick arrows, utilized to perform specific tasks.
When Thor broke the perimeter S.H.I.E.L.D. had set up around Mjølnir, Hawkeye was one of the agents who responded to Phil Coulson's order to neutralize him. Although Coulson requested that a firearm is used for the job, Hawkeye chose the Mathews Apex 7 compound bow instead. Hawkeye aimed at Thor from an aerial position in a crane but ultimately did not fire.
Hawkeye used once the Wristbow as his weapon during a security exercise to test the security systems of the Helicarrier, where he was disguised as a mercenary who had to battle Natasha Romanoff. Hawkeye used a newer model of the Wristbow during his time after the Decimation that contained several smaller arrows that he could fire with ease if he wasn't using his bow.
Heckler & Koch P30
Hawkeye carries a Heckler & Koch P30 as his main sidearm, holstered his left leg during any of his missions. He used it to fire at Nick Fury and at Maria Hill's car while he escaped from the Joint Dark Energy Mission Facility after being brainwashed by Loki. He still carried it during the Clash of the Avengers, but he kept it holstered not to harm his former allies.
Busse 'Hawkeye' Dagger
This dagger was made by knife manufacturer Busse, and was made specifically for Hawkeye (though this design would be standardized, replicated, and sold as an official Busse product). He used this blade while fighting with Black Widow on board the Helicarrier during his raid, on Loki's behalf.
Clint Barton resorted to using one of these guns to confront Pietro Maximoff at Avengers Tower, shooting it to the glass floor below Maximoff and making him fall to the floor below.
Hawkeye uses an arrow cartridge capable of holding nine collapsible arrows. He stores a case on the outside of each leg, which easily come off and quickly expand the nine arrows.
Barton carried a collapsible metal baton hidden under his quiver. He tried to use it to attack Vision, but it shattered in half against the android's Vibranium skin once he had increased his density.
Going under a different guise after the Decimation, Barton started using a different an assortment of weaponry, similar to that of a samurai, including wielding a katana when going around killing criminals who survived. Barton continued to wield the katana when he was reunited with the Avengers, fighting against Thanos and his army.
Going under a different guise after the Decimation, Barton started using a different an assortment of weaponry, similar to that of a samurai, including shuriken when going around killing criminals who survived. Barton used this weapon to throw at enemies that were not at close range.
Ronin (MCU)'s equipment
The fifth uniform resembled that of a samurai, with a primarily black suit with gold outlines throughout it. It features a black mask with a gap over the eyes, a hood, and armor on the arms and legs. There is a belt that contains his smaller, projectile weapons, as well as a back holster for his sword, and a new Wristbow. When Barton reunited with the Avengers, he wore a altered version of the Uniform without the gold armor, mask and hood.
Advanced Tech Suit
This suit was designed in order to time travel through the Quantum Realm safely. It is a white, red and black suit that materialize around the wearer's regular clothes, managing to be summoned when time travel is required again, and disappear when no longer in use. It has size-shifting adaptability down to subatomic levels and a wrist gadget that allows for displacement through time and space.
