• It can hold 5 .22 caliber cartridges.
• Unlike the many early 3D-printed firearm designs, which were overbuilt in order to withstand the pressures and strain on the material from modern gunpowder cartridges, the Reprringer is small and only slightly larger than an equivalent gun made from steel.

• Created roughly after a year the first-known metal 3D-printed gun was produced.
• Has the word "Reason" etched on it, along with an excerpt from the Declaration of Independence on the barrel.

• First 3D printed railgun structure.
• Closed source - designs and code released to research institutions only.
• Employed a mixture of traditional and additive manufacturing. Rails were traditionally machined, as well as the fasteners and electronics.

• Uses a plastic frame, slide, and fire control components with a steel barrel liner, breechblock, firing pin, and spring.
• First in line of "PG22" single shot pistols and revolvers.

• The MKII was released to work with a string of smaller releases, including an improved barrel making process and V2 Menendez Mag. Includes the "ButWhatAboutAmmo" tutorial for fabricating ammunition.

• A mostly printed .22 LR pistol. Uses a DIY metal barrel, firing pin, and spring.

• The receiver was able to handle enough stress to fire more than 600 rounds.

• Charon V3 weighs 0.2 pounds and showed no signs of strain after 96 rounds of 5.56 AR-15 ammo were fired.

• According to the creators, "It requires a bufferless upper to function, such as the ARAK-21 or Rock River Arms PDS Carbine, or a regular upper with a CMMG Style .22 LR Conversion installed."

• Based on Colt CM901.

• Compatible with Hi-Point C9, CF380, JCP, and JHP parts.
• Extremely cheap due to the high availability of the required parts kits.

• First 3D printed frame to be successfully tested with 1000+ rounds full auto in one sitting without failure.

• Utilizes a 1911 slide for the upper, and an AR-15 fire control group.
• An updated version, called the 3011DS, allows the use of double-stack higher capacity Remington and RIA magazines.

• A 3D-printable frame for the Avidity Arms PD10.
• This design is notable as the first firearm released by commercial company designed to be 3D printed.

• The magazine holds 30 rounds.
• The initial prototype was created using an Objet Connex26 using VeroClear printing material (a transparent material) in order to show the magazine's round count and feeding action.
• It was able to handle enough stress to fire 342 rounds and can fire 227+ rounds in quick succession.

• A 30-round AK-47 magazine.

• During testing, the bullet penetrated a 2×12 piece of pine wood, creating a hole in a wire reel.

• Designed to tame the recoil and muzzle rise of an AR-15 semi automatic rifle chambered in 5.56×45mm NATO (.223).
• It fired 7900 rounds during testing on semi-auto. During a test on full auto, 10 magazines of 62 grain green tip 5.56 rounds were fired without any issues.
• US Special Operation Command's (USSOCOM) Science and Technology Directorate invited Neal (the owner of Sintercore) to demonstrate the 3DX muzzle brake for possible use by its elite troops. They tested it on August 5, 2014.

• An additively manufactured titanium weapon suppressor. It is 50% lighter than some conventional steel suppressors.
• Oceania Defense has made three variations of the 5.56mm/.223 suppressor so far: the 556-45 Samson (an AR-15 suppressor designed to operate on semi auto Short-barreled rifle to 12.5" barrels), 556-SBR (designed for hard use on 10.5" barrel for AR-15 firearms in 5.56mm/.223 ammunition) and 556-45 Suppressor (direct thread on suppressor which overlaps the barrel designed to reduce a baffle strike)

• An additively manufactured titanium weapon suppressor.
• 50% lighter than some conventional steel suppressors.
• Oceania Defence made 3 variations of the 7.62mm rifle suppressor. the 300 BLK Long (designed for use with the 300 AAC Blackout cartridge in both subsonic and supersonic. It fits under the rail of a Samson or similar rail system on the AR-15-type rifle, but can to perform acceptably on bolt action 7.62×51mm/.308 rifles as well), 762-AR10 Suppressor (designed for the AR-10/LAR-8 7.62mm/.308 rifle but will also work with any bolt-action rifle in .30 caliber or less) and 762-G3 Suppressor (designed for the Heckler & Koch G3 and fits the HK91 series of 7.62mm/.308 rifles, as well as the HK33 and HK93 series of 5.56×45mm rifles).

• Long version is designed to operate on 9×19mm Parabellum carbines firing fully automatic.
  • It fits under the rail of a Samson or similar rail system on the AR-15-type rifle.
  • This is a sealed can and is only suitable for use with jacketed bullets.
• Pistol version is designed with a Neilsen which allows it to be used with most of the common John Browning tilting-barrel designs, including the swinging-linked M1911 and the cam-lock system operated Glock pistols. The Neilsen is an assembly in the aft end of the suppressor that allows the gasses to push the suppressor forward while allowing the unimpeded rearward movement of the barrel and slide assembly using a stainless steel spring and titanium piston.
  • It is able to function well with a wide range of ammo, although its sound reduction performs best with subsonic bullets heavier than 124 grains, with 147 or 158 grain bullets being the quietest.
  • It is designed to be run wet or dry, averaging 127.7–128.4 dBA with 147 grain or 127.6–134.2 dBA with 124 grain when dry and 123.1 dBA with 147 grain or 129.1 dBA with 124 grain when wet.
• It is an additively manufactured titanium weapon suppressor. It is 50% lighter than some conventional steel suppressors

• A 75-round drum magazine for .223 Remington/5.56 NATO AR-15 rifles.

• 75-round drum magazine for 7.62×39mm AK-pattern rifles (e.g. AK-47, AK-102, AK-104 and compatible variants).

• "The idea was to create a muzzle brake with no equal; one that turns the recoil of an AR-15 into a slight push with zero muzzle rise."
• Produced for 5.56x45mm (.223 Rem) or .224 Valkyrie rifles with 1/2x28 threads.

March 2021 (v2)

• Dry fire testing of the v2 design suggested a lifetime of over 1000 rounds.

• A fully printable swift link that enables full-auto fire by pressing on the disconnector. Compatible with most AR-15 lowers.
• Classified as a machine gun by the ATF.
