An inline blowback is a type of blowback design. A blowback marker is one that when the trigger is pulled, the sear is released, which allows the striker, which is linked to the bolt, to slam into the valve, which releases air into the bolt, which is redirected out the barrel. The valve also releases air back into the striker, pushing it back and recocking the marker. An inline blowback is where the bolt, striker, and valve are all adjacent horizontally in the same tube, instead of in a stacked tube blowback where the valve and striker are in one tube, and the bolt is in another tube above the valve and striker.
The blowback design in general is the most affordable way of making a semi automatic paintball marker, that doesn't need the use of compressed air/nitrogen or any type of regulation on gas.
Operation
The operation of an inline blowback marker can be separated into four stages:
Ready:
The compressed mainspring puts pressure on the striker, often called a hammer or "rear bolt", which is held in place by the sear. The bolt is linked to the striker by the linkage arm, and held clear of the feed neck, which allows a paintball to drop into the chamber.
Chamber:
The sear is depressed or "tripped" by the trigger, which releases the striker and allows the mainspring to push it forward. The linkage arm causes the bolt to move forward as well, pushing the paintball into the end of the barrel and sealing off the feed tube. This is where any misfed paintballs will be chopped.
Strike:
The striker hits the seal pin on the valve, opening the cup seal inside and allowing compressed gas to escape. A portion of this gas flows through the space between the seal pin and the valve, forcing the striker backwards and resealing the cup seal.
Fire:
The remainder of the gas flows around the valve through wide grooves milled in its sides and is channeled by the power tube to flow out the center of the bolt, propelling the paintball. The power tube usually has a screw in front of the valve which is twisted to restrict the flow of gas and change the final velocity of the paintball. Once the striker is forced back far enough, the sear catches it and the marker is back at the "ready" stage.
Ideally, the firing stage will complete before the feed tube is reopened. This prevents gas from venting out the tube instead of propelling the ball, which would require a greater volume of gas to bring the ball to the correct velocity. However, this is not the sign of a sloppy marker, as a slight pressure on the paintballs in the feed tube can help "unjam" standard gravity-fed hoppers. Some of the most common inline blowback markers are made by Tippmann.
Heavy, fast-moving striker can cause more recoil than other designs.
Basic troubleshooting
Some inline blowback markers will leak air from the barrel when uncocked. The striker sits forward against the seal pin, causing the cup seal to open enough to leak air from the valve, which escapes out the barrel. Pull the charging handle or knob to pull back the striker and remove the pressure from the seal pin. However, during storage, you should always remove the air source and leave the marker uncocked. The rear spring can be damaged if stored a long time in a cocked position.
Tippmann is an American manufacturer of paintball markers and paintball equipment, including military simulation (MilSim) kits. A related company, Tippmann Industrial Products manufactures manual and pneumatic heavy-duty sewing machines primarily used for leather, other leather-related equipment, and some industrial products. Originally a family owned business run from Fort Wayne, Indiana, in 2004 Dennis Tippmann Sr. sold a majority ownership stake to Summit Partners, a private equity firm. Tippmann designed the first automatic marker, the use of refillable air systems in place of 12 gram cartridges, the "Cyclone Feed" system, the "Flatline" barrel, and the Tippmann C-3, the first propane-powered marker.
The slide on the majority of fully/semi-automatic pistols is the upper part that reciprocates ("slides") with recoil during the gun's operating cycle. It serves as the bolt carrier group (BCG) and partly as the receiver, and generally houses the firing pin/striker, the extractor and frequently also the barrel, and provides a mounting platform for iron and optical sights.
A fully automatic firearm is said to fire from an open bolt if, when ready to fire, the bolt and working parts are held to the rear of the receiver, with no round in the chamber. When the trigger is actuated, the bolt travels forward, feeds a cartridge from the magazine or belt into the chamber, and fires that cartridge in the same movement. Like any other self-loading design, the action is cycled by the energy released from the propellant, which sends the bolt back to the rear, compressing the mainspring in readiness for firing the next round. In an open-bolt gun firing semi-automatically, the bolt is caught and held at this point by the sear after each shot; and in automatic open-bolt fire, it's caught and held in this manner whenever the trigger is released. In contrast to this, in closed-bolt guns the trigger and sear don't affect the movement of the bolt directly.
The Angel is one of the first electropneumatic paintball markers. It was manufactured by Angel Paintball Sports starting in 1997 and was introduced alongside Smart Parts' original Shocker.
The Autococker is a closed-bolt semiautomatic paintball marker manufactured by Worr Game Products (WGP). It was one of the first paintball markers to be designed specifically for the sport, and has long been known throughout the paintball community for its popularity and customizability as well as its complexity. It is commonly believed that the closed-bolt design of the marker makes it inherently more accurate than its open-bolt counterparts, though this is disputed.
The A-5 is a semi-automatic pneumatic marker made by Tippmann for playing paintball. Inspired by the look and feel of the Heckler & Koch MP5K submachine gun, it was first produced in 2002 in the USA. It utilizes a loading concept called the "Cyclone Feed System".Tippman A5 is the fully loaded model in the Tippman arsenal and cost more due to all of the built in features that come standard. Tippman guns they are reliable, rugged and dependable. With the built it cyclone feed the marker really has a feature that is unique in paintball. To get the same performance from a hopper on any other gun would require an electronic hopper, which adds considerably to the cost.
Smart Parts was a paintball manufacturing company in Latrobe, Pennsylvania, which filed for liquidation on July 28, 2010. As of August 22, 2010 Smart Parts Assets and IP was Acquired by Kee Action Sports.
A paintball marker, also known as a paintball gun, paint gun, or simply marker, is an air gun used in the shooting sport of paintball, and the main piece of paintball equipment. Paintball markers use compressed gas, such as carbon dioxide (CO2) or compressed air (HPA), to propel dye-filled gel capsules called paintballs through the barrel and quickly strike a target. The term "marker" is derived from its original use as a tool for forestry personnel to mark trees and ranchers to mark wandering cattle.
Paintball is an equipment-intensive sport and in order to safely conduct a game, every player requires a marker with propellant to fire the paint, a mask to protect the eyes and face, paintballs, and a loader to hold them. To ensure safety off the playing field, a barrel sock or plug for the marker is also compulsory.
A ball detent is a simple mechanical arrangement used to hold a moving part in a temporarily fixed position relative to another part. Usually the moving parts slide with respect to each other, or one part rotates within the other.
The Automag is a paintball marker designed by Tom Kaye and produced by Airgun Designs, Inc. It bears the distinction of being the first semi-automatic marker ever to win a paintball tournament. Team Swarm used Automags in their victory at the 1990 International Masters.
The Tippmann C-3 was the first propane powered paintball marker. It operates on a unique system Tippmann calls 'Propane Enhanced Performance'. The name 'C-3' may refer to the chemical formula of propane, C3H8.
The Spyder MR1 is a MilSim paintball marker designed and manufactured by Kingman Group, now superseded by the Spyder MR2 and MR3 models.
The Bushmaster 2000 is an electro-pneumatic paintball marker produced by Indian Creek Designs, (ICD), a manufacturer based in Idaho.
The CCI Phantom is a Nelson-based pump action paintball marker developed and produced by Mike Casady. Production began in 1987 after about six months of prototype work. The name for the marker was derived from the much more stealth-oriented and drawn-out style of play that was typical when the game was first developing. The Phantom was designed to be powered by a single 12 gram CO2 powerlet, but larger tanks may also be used by removing the powerlet adapter or using a dummy powerlet. When first introduced the marker featured a fixed barrel assembly referred to as a "unibody" combined with a modified Crosman air pistol frame and brass bead sight. However, since roughly 1989 the body and barrel of the marker have been two distinct parts and no longer feature the bead style sight. The marker is also capable of supporting bulk gravity fed hoppers by using a different breech type. The Phantom is one of only a handful of readily available markers acceptable for use in the various forms of stock class paintball. However, because the Phantom is capable of auto-triggering and features barrel porting it is considered to be a modified stock class marker.
The ICD ProMaster is an electropneumatic paintball marker manufactured by Indian Creek Designs and first released in 2005. The Promaster was designed to replace the aging Bushmaster 2000 model, which had been Indian Creek Design's flagship marker between 2000 and 2004.
The ICD Freestyle is an electropneumatic paintball gun, or marker, made by Indian Creek Designs of Nampa, Idaho. Except for the air line, it is built completely of precision-machined aluminum.
Airgun Designs, Inc. (AGD) is a manufacturer of paintball markers and equipment formerly based in Wheeling, IL. The company is now based in Cary, IL. They are best known for manufacturing the Automag paintball marker. Tom Kaye founded AGD in 1987. As one of the oldest paintball companies in existence, AGD has been responsible for several innovations now common on the paintball scene.
The TPX/TiPX is a magazine fed paintball pistol made by Tippmann. New to the paintball pistol market, Tippmann released the TPX in 2009. This paintball marker uses an air system that allows for 12 gram CO2 cartridges to be placed underneath the barrel. This was meant to eliminate bulk in the grip of the marker caused by placing the CO2 cartridge in the magazines. In 2011,Tippmann changed the name of the pistol to the TiPX to market all the improved parts at that time, as well as differentiate it from the TPX baseball line by Louisville Slugger.
An electropneumatic paintball marker is a paintball marker that uses a pneumatic solenoid to actuate the hammer and/or bolt's movement.
