However, he did use an incredibly powerful blaster - the LL-30, and was an excellent sharpshooter. So, technically, if you shoot it enough with a good enough gun, it'll pierce through the beskar.
The purest form of beskar was capable of repelling the strikes of a lightsaber for brief amounts of time, and could withstand direct blaster fire. Pure beskar could still be damaged by weapons also made out of beskar; because of this, making weapons out of beskar was considered illegal by the Children of the Watch.
Mandalorian beskar armor, while incredibly tough, has a major vulnerability - a gap between the helmet and the breastplate, which a skilled sniper like Aurra Sing can exploit (as shown in Star Wars: Revelations.)
This has not been confirmed by canon yet, but it is the likely reason, seeing as the only weapon that could absolutely destroy beskar - or at least the person wearing it - is the Arc Pulse Generator.
Throughout the Star Wars franchise, beskar is extremely blaster-resistant, though there are some exceptions to this. The Mandalorian and Death Watch warriors in Star Wars: The Clone Wars and Star Wars Rebels are shown being killed by single blaster bolts, which penetrate their beskar armor.
These melee weapons, including electro-bisentos (glaive), Bilari electro-chain whips (incredibly flexible sword), and vibro-arbir blades (double sided weapon), were not only capable of deflecting lightsaber blows, but they could also puncture straight through Beskar armor, as shown in Mandalorian Season 3 when a team ...
Boba Fett's armor was a suit of customized Mandalorian armor worn by Boba Fett, a human clone who became a bounty hunter. The armor was made from beskar. It consisted of a helmet, a cuirass, vambraces with retractable wrist blades, and a Z-6 jetpack.
Beskar is supposedly resistant or proof to lightsabers, but is it strong enough to prevent itself from being crushed by someone using the force? Beskar is an extremely tough metal. It's unable to be affected by blaster bolts and even lightsaber strikes.
But the closest thing we would have in real life is probably Tungsten: Now there's actually an alloy called Tungsten titanium carbide which is supposedly a mixture of the two up above.
Well, bullet and lightsaber resistant. Get in a decent hit with a lightsaber and you can kill someone in beskar armor. If you don't have one of those, get a bigger blaster. Even if the shot itself doesn't penetrate, the shock would eventually become lethal.
Notably, the Dagoyan Masters of Bardotta regarded the Jedi as thieves and kidnappers because of that practice. Some Mandalorians, most notably members of Death Watch, held a grudge against the Jedi for their perceived crimes against Mandalore during the Mandalorian-Jedi War.
During this same period, Jedi Knight Bardan Jusik was well known for wearing clone trooper armor into combat, and later on even full Beskar'gam. Later into the war, many Jedi wore chest plate armor that resembled modified clone armor designs.
Beskar is known to be able to withstand direct lightsaber hits. Lightsabers can withstand force lightning. So if beskar can withstand lightsabers, and lightsabers can withstand force lightning, then by the process of elimination, Boba's armor could probably withstand force lightning.
Cherished for its incredible strength and durability, beskar was notable for being able to withstand blows from even a lightsaber, and was commonly thought to be nearly indestructible, making beskar more prized than durasteel or cortosis.
The plasma that comes from a lightsaber blade: Can cut through pretty much anything it touches. exceptions include Beskar, or Mandalorian iron, the strongest metal in the galaxy, as well as the scales of a Zillo beast.
One of the most memorable moments involving a lightsaber is when it cuts through a thick metal door. The ability to melt through such materials suggests that the blade's temperature must be incredibly high, likely 20,000 to 25,000 degrees Celsius.
Of the two fictional metals, vibranium is far more effective at deflecting physical blows and absorbing forceful impacts. Vibranium's ability to absorb and store kinetic energy makes it more adaptable rather than just durable.
Jango Fett's armor was partly made of durasteel, and General Grievous had some parts of his body made of this material. Darth Vader's armor was mostly made of durasteel, as was Boba Fett's before he upgraded during the Second Galactic Civil War to armor made of beskar.
In contrast, Din Djarin's armor was made from pure beskar, earned through the bounty on Grogu. This made Djarin's armor rare and even more durable than normal Mandalorian armor, allowing it to stay shiny and undamaged even when he walked into a barrage of blaster fire.
Obsidian in the armor supercharged Vader's dark side power, turning anger into a power source. The Empire couldn't use beskar in the armor due to a lack of knowledge on forging the Mandalorian alloy.
It's possible that Gideon used the pure beskar from a fallen Mandalorian in order to craft his own helmet from scratch, or he just used it as is. It's also a possibility that Esposito's villain is using the same general helmet of a dead Mandalorian but made some alterations to it along the way.
When Djarin reunited with the surviving members of the Tribe on Glavis Ringworld, the Armorer informed him that beskar was only for armor, not weapons, as the spear was capable of piercing Mandalorian armor. Djarin had her melt the spear and reforge it into a garment for the foundling Grogu.
