I do not have an online shopping cart. Once installed, that piece of software will automatically bill each customer for everything. As I run out of original material, I am constantly having to change customers' orders. Most orders would require more work issuing credits. If I were selling newly made items, online clearance of credit cards would not present a problem. All credit card and contact information is on each page. You can call in your credit card, email it, or send it by mail.

Grenade Launchers and Associated Equipment

Note:  No Sales or Shipments of Grenade Launchers to the State of Kalifornia

Recently uncovered in one of my buildings is a crate of M7 Grenade Launchers. They are mostly Fay and Scott, but there are also a few other contractors. As time allows, I will go through them and list the available contractors.

All items on this page are listed for sale as collector items only. Anybody who mentions he is purchasing these items to launch dummy grenades, or pyrotechnic signals, will be turned down from sale.

M7 Grenade Launchers produced by Knapp Monarch (KM). This is my favorite contractor as KM was the only producer to make every type of WWII Grenade Launcher; M1 (03 series), M2 (1917 Enfield),  M7 (Garand), and M8 (Carbine). Some KM are still in VCI wrap from the 1950's, others are not. All are approximately 95% condition and finish is like new. PHOTO  

M7 Grenade Launchers produced by Fay & Scott.  This launcher was the only M7 that did not have a staked launch tube. All Fay & Scott launchers had tubes that were roll crimped. These have approximately 95% finish and are like new.  PHOTO  SOLD OUT

M7 Grenade Launchers produced by Hawley Smith Machine Company, which are one of the harder launchers to find. These launchers were packed in VCI paper during the 1950's. During storage the paper stuck to the launchers. PHOTO  Oil and scrubbing should remove the paper.

M7 Grenade Launcher, Black Oxide Finish, some pitting. The launchers also have some lose latches. These launchers are ideal for re-enactors who do not want to spend collector type money. Each launcher has been refinished and has some pitting under the black finish. Samples are as follows: PHOTO TUBE,  PHOTO BRACKET. Sorry, no choice of makers on this one.  SOLD OUT

M15 Grenade Sight, WWII. These are new, never used and complete. Includes the sight, base and screws, carrying case, and the trajectory chart from 1944.  PHOTO The sight and components are new, but the carrying case may have slight rust on the M1910 hook (belt hook) $10.00 plus shipping.

M7 Grenade Launchers converted to fit the 1903 series rifles. Back in the mid 1980's, this was done commercially. Due to the increase in the price of M1 Launchers, which were starting to hit the $100.00 mark, this launcher was converted for those who wanted to build a display. This is an identical copy of the M7 converted for the South Vietnamese during the early part of the Vietnam war. PHOTO The original Vietnamese writing was left off to show it was not an original item. However the launcher was marked with the 03 markings. Overall condition is like new.  SOLD OUT

M7A3 Grenade Launcher, produced by Sun Ray Photo Co. PHOTO Some of these were used with corrosive ammunition and were refinished a dark black. I have several different conditions.

Prices do not include shipping:

Excellent Condition About 95% condition


I also have a few Acme Machine Works and KR Wilson SOLD OUT. Email for price, condition and availability.

M76 Grenade Launcher for the M14. Although not rare, this is one of those launchers that are hard to find when you are seeking one.  PHOTO  Used mostly by the Marine Corps, they were also issued to the Army for launching pyrotechnic signals.  Call for availability and price.

Your Government At Work

M7A1 Grenade Launcher, DEMILLED. The M7A1, the only launcher produced by Rock Island Arsenal, is quite a scarce launcher. One of the reasons for its scarcity sits in a large drum in one of my buildings. Now you can purchase a demilled launcher for spare parts, or to try to reconstruct one. This version has a serviceable bracket, locking latch and recoil mechanism.  The government crushed the tube. PHOTO $50.00 plus shipping.

M7A1 Grenade Launcher, DEMILLED. This version has a serviceable bracket, locking latch, recoil mechanism, and grenade retaining spring. The government torch cut the tube. This one is ideal for those missing a retaining spring for their M7 launcher. There are also some individuals who have produced their own version of a muzzle brake by machining and welding. Just 2 left.   PHOTO $75.00 plus shipping.

Gas Cylinder Lock Screws Ordnance Part No. B147851-Not Your Common Ordinary Item

These locks screws were the first vented screws produced. The screws were Remington's design which was delivered with the T14 Launchers, for trial. These screws are now known as the "Non Closing" type, not be be confused with the massively produced and used, "Poppet" type. They have a small curled wire form, referred to as a retaining spring, which retained the valve. Once the lock screw was opened by the M7 Grenade Launcher, the rifle was no longer semi automatic, due to the venting of the gas system. This was done to prevent damage to the rifle and injury to the operator, when launching projectiles. In order to return the rifle to semi-auto, the launcher had to be removed and a round fired. The gas pressure would then close the valve. The bulk of the WWII grenadiers originally had these lock screws until the poppet type was produced in quantity and distributed (circa Apr or May of 1944). After the war Rock Island had a project to removed this type lock screw from unused launchers, pack them with an M15 sight and dispose of these screws as most rifles at that point had the poppet type already installed. Most of these screws were scrapped. Very few survive today.

After having gone through original packs PHOTO from WWII, I sorted them as shown below. The most common one in this batch was the SA light finished, which history shows to be the second scarcest. The Carbon Steel version is by far the scarcest, having found only 3 out to 250 plus.

To learn about the history of these screws, click on this link:  Lock Screws

Most M7 Grenade Launchers require one of these S marked screws to restore them to WWII combat configuration.

Many do not understand that these Lock Screws shown below are very rare.   Approximately 36,000 were produced during late 1943 (Sept to Dec) and these were all used with Grenade Launchers on the M1 Rifle.  The later version came out and some say Jan, 1944, but my contracts only show them started in March of 1944.  Anyway the requirement was to change this Lock Screw with the later version and most never occured.  After WWII, Rock Island Arsenal had the responsiblity to get all these early versions and make sure they are never to be used again.  Very few exist today and I got a few dozens on an Army Bid circa 1987-89.  If you read the histories of the screws, you can learn a lot more about these.  They are RARE.

Inert Rifle Grenades

M29 Anti Tank Rifle Grenade, Practice (T42). This is the scarcest of all versions of US Rifle Grenades. It was also known as the Energa Rifle Grenade, its Belgium designation. In production from only 1950-1953, not many survive. The training version was designated M29 and was the design of Mecar, of Belgium.

The M29 is quite heavy compared to WWII Anti Tank Grenades. It replicated a huge 75mm warhead, which resulted in one heck of a wallop against armor. The M29 was used in training until 1961, when the M31, a lighter, slimmer design replaced it.  Unlike the M31, the M29 was used over and over again due to its ability to hold up to ground impact. Available for sale are the earliest versions in black, marked with the test designation T42 and are dated 10-53.  It was not until later that American production made them in blue, the color of inert ordnance.  The black ones are quite scarce.

I have none in mint condition. On auction boards they bring very big money. Because these were used in training, I am pricing them reasonably. This batch came from Pueblo Army Depot in 1962.

Each M29 started out with 6 stabilizing fins. All that are left are listed below. Overall the condition is pretty good. As so few were made 55 years ago, what is left fits many collections. Others would repaint them and/or install fake markings. To keep their history as is, I am selling them as they exist 55 years later. For display purposes each warhead can be rotated so the missing fins are hidden in the rear.

5 out of 6 fins version

Sold Out

2 or 3 out of 6 fins version, only ones left, and many are missing some of the markings because they were well used from the 1950's up to 1961.

Grenade Project Adapter, M1A2. This adapter was originally an M1 from WWII, which held the MKII "Pineapple" Grenade. During the Vietnam War, Ordnance modified this design to accept the M26 "Lemon" Grenade. PHOTO  $26.50 plus shipping.

M16 Grenade Launching Retaining Spring, fits on barrel directly behind the Flash Hider. Manufactured during the 1960's, this retains the rifle grenade until launched. $ 25.00 plus shipping. There are two different fakes being made and most are Gray and some are 3 to 5 dollars, because they are baking them less than 75 cents in either China or India.  These are originals with proper finish.  PHOTO
