List of Sons of Guns episodes

After seeing a suppressed shotgun in No Country For Old Men (film), a man comes into the shop and challenges Will to build it. A cannon collector brings in his $250,000 Civil War Confederate cannon, but Will wants it inspected before he and his team shoot it. With the initial design of a shotgun suppressor a failure, Will is forced to try again. During the firing of the cannon, Will gives shop apprentice Kris a "six-pack bonus" and lets him fire the first shot the cannon has seen in over 100 years.

Will briefly talks about his employees. A local SWAT consultant, Marco, asks Will to design a gun which will cut down on the time needed between breaching a door and switching to a primary firearm. Will sets out accomplishing this with a combination shotgun-assault rifle. The team is worried about meeting deadlines with a malfunctioning mill. Will buys, to daughter Stephanie's displeasure and economic concern, a grenade launcher. Will attends a live fire test of his product, with excellent results. This weapon design is easily purchased from other weapon makers that have sold it for many years, Will states this in the episode. That is where the name came from "Master Key"

After an encounter with a fellow veteran Woody Williams in a war museum, Will agrees to restore the fellow Marine's World War II flamethrower to working condition. It becomes clear to the shop that Will has a mysterious fear of using the weapon, however. Customers of the shop's store include a man looking to modify a purchased AK-47 to accept 30 round magazines, and a man who wanted to resell a fake M1 carbine. A husband comes in with his wife and works with Will to pick out a home defense weapon. After a friendly competition to determine who would use the flamethrower, the shop tests it out with a surprising conclusion.

Will spends an enormous amount of money to buy an M2 Browning ("Ma Deuce") machine gun kit, but it becomes clear he cannot put it together on his own. Stephanie works hard to sell enough guns through the store to compensate for Will's purchase, with the shop betting whether she can accomplish this feat. Stephanie lowers the price of a store weapon in exchange for a night fishing trip. The test firing of the Ma Deuce does not go without a few hiccups.

Firearms instructor Tiger McKee commissions Red Jacket with building five copies of his prototype "Shootrite Katana" lightweight assault rifle. Shop gunsmith Vincent is assigned the job of assembly. Glen, Will's friend, finds a rare "coffee grinder" Civil War–era rifle, but its authenticity is questionable. Kris, the shop apprentice, makes a mistake in painting the Katanas. Finally, after a late night of final assembly by Vincent, the gun gets tested by Tiger with great results.

Will has a swivel gun delivered and has a mount manufactured by another shop. After demonstrating an external suppressor for a client (Joe), the client asks Will to produce an integral AK-47 suppressor. Will puts the final result through its paces, and the client is pleased with the results. After modifying the swivel gun's mount to suit his preferences, the team gives it a test fire on a lake.

Will briefly forgets about shop apprentice Kris' birthday, and has to decide on a gift to give him. Glenn, Will's friend, comes into the shop and asks Will to make reproduction World War II bazookas to be used in reenactments. Although Kris makes a minor mistake, fabrication goes smoothly. However, there is a problem with the accuracy of the rockets and gunsmith Joe is tasked with fixing it. The target on which the bazooka is tested is shocking to some, but testing goes smoothly and an immediate demand for the final product surfaces.

Shop employee Charlie works Will to build and sell a "Red Jacket" collectible samurai sword and machete combination blade. The local sheriff asks Will to modify a Thompson ("Tommy") sub-machine gun for use with his SWAT team. The shop sets to work on the sub-machine gun work which suffers from multiple initial firing troubles. Charlie's efforts at sword making become a complete failure, forcing Will to take control. Will demonstrates the final Tommy gun result for the sheriff and a pair of his deputies, leaving the clients happy.

A movie producer visits the store and wants Will to convert a regular sub-machine gun into a gun that will only fire blanks. Although the money is good, time is short for the job. A counterfeit Red Jacket gun comes back into the store for warranty service. Stephanie asks the guys to surprise her dad with a double-barreled shotgun converted into a "leopard gun". Charlie is set to do the job, but it becomes clear he needs help. Will, Stephanie, and Kris visit the movie set to demo the blank-firing gun, but the result of the trip is more than one surprise, including a visit with actor Jeffrey Dean Morgan.

Red Jacket is tasked by an antique gun shop to restore and test a 19th century pistol. DB, a security contracting firm agent, asks Will to build a remote-control machine gun which can be mounted to a vehicle. Will consults with Louisiana State University for the stabilization system, but an argument arises over the remote control for using the gun. Meanwhile, a strange man comes into the store. The remote-controlled machine gun is put through its paces.

A combat disabled Marine comes to Will and asks him to build a gun system which would allow him to hunt from an ATV with a shotgun using his single functional arm. Stephanie and Will work on finding some additional help in the shop, but Kris has a problem with one of the applicants. Will becomes angry with Vince when Vince believes their ATV-shotgun mounting system is flawed. A promising applicant (Glenn Flemming, AKA "Flemm") comes to interview and tryout for the open job and impresses Will straight away by bringing along a selection of his previous builds/projects including a fully rebuilt & restored WWII German MG42. Meanwhile the ATV gun is tested in the field by the client and the price is a surprise.

A police officer comes into the shop with a M1919 Browning machine gun and asks Will to convert it into a shoulder-fired weapon for a competition—in a few days. The crew sets about replacing and adding parts to make the 1919 shoulder mounted and lighter. The aftermarket parts they install have multiple issues requiring Vince to work through the night to meet the client's deadline. The demo becomes, according to Will, "a hoot". Flemm gets hired on with Red Jacket.

Security contractor Marco returns to Red Jacket and requests Will to design a non-lethal weapons system to deter sea-based pirate attacks. Based on a Katyusha rocket launcher design, Joe takes the lead designing the rockets and launching system. A customer comes into the shop with a 1910 Maxim machine gun, but the costs of repair are immense. Kris shows his brother around the shop. Testing of the rocket array goes off with a bang.

A friend of Vince asks him to build a weapon which can kill an alligator humanely without damaging the valuable hide. Will tries to ease the workload on the shop by hiring mechanic Christopher/"Mikey" as well as asking Vince and Kris to help out on the phones. Flemm assists Charlie with testing some vintage weapons. Vince and Will go out to the field to test the alligator kill stick.

An active duty navy gunner asks Will to tie two M16's together for better fire support ability. However, Will tasks Joe with designing a water cooling system when the gas tube/barrel turns bright red under sustained fire, causing premature primer detonation. Stephanie and a customer test out some shotguns.

Will is inspired by Charlie's cool folding pellet gun to get the Red Jacket team to create a combination flashlight and survival kit that unfolds to become a semi-automatic M11 SBR rifle. Then, new guy Flem is tested when Will tasks him to build an MG 42 machine gun—aka "Hitler's Buzzsaw"—from a parts kit. As the build gets underway, Charlie's excitement causes him to prematurely advertise the product, much to Will and Stephanie's dismay; meanwhile, Vince is not too thrilled at having to build "MacGyver's Lunchbox".

With the 10 year anniversary of Red Jacket approaching, Will looks back on how far Red Jacket has come. To celebrate, Will decides to build a 3-in-1 M16 machine gun "triamese" as his Anniversary present; meanwhile Stephanie secretly organizes a surprise party; however, an error made by Kris is going to make it more difficult than expected as people begin showing up by the numbers before the celebration. An unexpected object falls out of an antique gun repair, which turns out to be a tooth. Will's surprise party goes off with a bang.

Will decides to build a gun with the accuracy of a sniper rifle and the semi-automatic dependability of an AK-47 despite the doubts of Vince. World Champion archer, Chris Brackett, asks Will to make an arrow gun and exploding arrows. A customer has Red Jacket bring a WWII Arisaka rifle back to firing condition, at the same time Charlie is given the assignment to search for its ammo. The popularity of "Sons of Guns" takes its toll on Stephanie.

This episode coincides with the second episode of the second season of American Chopper: Senior vs. Junior titled "Big Guns". Kris sketches up a crazy idea to create a chrome dipped 1919 into a chopper war machine - a gun styled to look like the handlebars of a motorcycle that might be made on American Chopper. Will then talks to Paul Teutul Jr. from Paul Jr. Designs and invites him (as well as Mikey) to come to the shop to test fire the new 1919 dragon gun. Stephanie is upset at the fact that she was not put in the loop in regards to the Teutuls visiting the shop. Vince requests help from Deep South Choppers and his tattoo artist to design aspects for the Dragon Gun. Once the painters complete the design, the team overlooks one minor detail which has Flem and the team scrambling to call back the painters. Meanwhile, world's fastest shooter, Jerry Miculek, stops into the shop and bets that he can shoot the Semi-Automatic, Silenced AK-47 faster than the factory full-auto version. Kris finally gets to use his "guitar gun" as a reward. Will and Vince head up to New York to see the PJD Team and give Mikey's birthday present from Paulie.

Will tackles the ultimate challenge: taking four MG 42 machine guns and combining them into a German version of the classic WWII "Meat Chopper" anti-aircraft weapon, but the question is will the team succeed or has the team finally bitten off more than they can chew. Then, a customer brings in a rare antique French palm pistol that sparks a father-daughter debate about how to run the Red Jacket business. Joe and Charlie create some flying targets on the side for the "Meat Chopper", but Joe's flying skills are something to be desired. (Taken from Discovery.com)

Meanwhile, Kris takes it upon himself to make a hunting rifle float for a customer much to everyone's chagrin. Will, Joe, and Charlie play with the concept of a gunpowder version of a Soviet Ballistic Knife. Flem and Steph begin to go at it in regards to a paycheck and Will has to step in the middle. Later, Flem gets tagged by one of the shop machines, which causes him to black out. Steph starts stressing out as paperwork piles up in the office. With the Mk19 close to completion, the team overlooks one minor detail, which could prevent the team from making the deadline and Will prepares to lose it. (Taken from Discovery.com)
