Who we are

Interfor Usa Group is a small FFL07 company specialized in the small batch manufacturing of tactical firearms and equipment.

Founded by long time firearms enthusiasts, the aim of Interfor is to re build legal military weapons for collectors, target shooters and weapons enthusiasts, so they can possess civilian-legal versions of their favorite military and historical firearms.

Due the high tolerance of the original military firearms and the scarce availability of spare parts and blueprints, each one of these guns must be rebuilt by hand and fine tuned and test fired before being shipped.

For this reason our production rate may seem low but we strive to fulfill orders from our customers in reasonable amount of time. Right now the backlog is about 60 days and we are working weekends to keep the production rate high. Pur best customers have ordered about 10-12 different models/version of firearms, so this must mean something.

On the other hand we can offer great flexibility to the customers, as our guns can be built exactly as the customer requests, making possible to have clones of very rare historical guns, often based on museum pictures or other scanty material.

We test fire each firearm before shipping to make sure that everything works and the customer gets a functional gun right out of the box.

Can see some of our builds in action on our Youtube video channel, Interfor USA Group or at the OUR FIREARMS page on this site.

We are also fully licensed importers (FFL 08) and registered State Department exporters of firearms and ammunition.

New video: a test fire of some of our builds. Sten MKV. Mp5 Mp5K.

 

This time we test fire some of pur builds we made for our customers. We made a Sten MKV rifle, a MP5 and two MP5K with different outfits.

For this test we used 9mm Norma 115gr @1200 fps but for these guns, especially for short barrels like the MP5K, we recommend the Nato load 124 grs. @1200 fps (or similar). The heavier bullets assures a smoother cycle even with heavy springs and dirty guns. While the 115 gr. is very good in pistols, the bullet weight could be not enough to push an heavy bolt from a short barrel.

 

New video: our Doorbuster 12 gauge firearm based on  Black Aces Magazine receiver

This time we wanted to build a door buster SWAT gun as much as legal you could have. The only legal way to do it was to start from a virgin Black Aces magazine receiver , add a SBA3 brace and a barrel just long enough to get to the minimum firearm overall length of 26". This implies that the gun cannot go under 26" overall length so the tube and brace CANNOT be legally removed.

We also made the Black Aces system a little more reliable and found a way to use PGM and Pro MAG SAIGA magazines on this gun (we will publish a video on this pretty soon).

The gun is very reliable and would say on a par with any Shockwave or similar. The PGM and ProMag magazines are even smoother than the original Black Aces mags. We will show how to modify them pretty soon. We also added a flashlight system and a solid front grip system. Enjoy.

New video: our AK Krinkov pistol with brace and our in house (non Franklyn) binary trigger

This time we stest fire our AK47 pistol in 7,62x39 with triangle brace and binary trigger. 

instead of using a Franklyn trigger we decided to test the Keybase binary design and worked perfectly after a couple modification (a longer tail).

The system is completely selectable (Safe binary semi) by the selector lever.

New video : how to assemble/disassemble a Velocity Firearms MAC10 system gun

Velocity Firearms MAC10 and MAC9 guns are somewhat different from traditional Cobray, Jaws and RPB Macs and no manual or video is available online. For this reason we decided to make a video on how to assemble and disassemble, with details on parts different from the traditional closed bolt MACs.

This video is dedicated to the late Sean Cody who was a great MAC expert and from whose site I learned a lot even before moving to the US and meeting him.

Test fir of our MP5 clone with Franklyn Armory binary trigger


 This time we test fire our MP5 clone with a Franklyn Armory binary trigger. This trigger IS NOT A DROP IN trigger as it is furnished without an ejector lever and, even in the best cases, needs a lot of fine tuning to provide a reliable functioning, so for sure you will need a gunsmith to install it or at least some gunsmithing skills. The secret is in the proper setup of the height of the ejector which is regulated by a screw in forward part of the trigger box. Once properly set up this toy give some satisfaction though.

A panoramic of our HK33 - 33k and 53 clones

 

This time we show a panoramic view of our 53 and 33k clones, both in 5,56 Nato caliber. 

We do also in .300 Blackout but prices will be higher due to higher cost of parts and ammunition to test. Barrel length are between 4.5 inches (53K) 8.5 (53) 12.5 (33K) anup to 16" (33). 12.5 barrels can be permanently extended to 16" using a 4.5 flash hider permanently pinned and welded to the barrel.

Interfor SA15 STUBBY - 5,56 Nato pistol with SBA3 brace

This time we rebuilt an old timer. A clone of the famous Olympic Arms SA15 "Stubby". 

In the '90s this gun was considered so revolutionary because it could work with 7.5" barrels. Adjustable gas block had not been invented at the time and the manufacturer invented a pig tails tube which was basically a full length tube which turned around the barrel to keep gas level down and control overgassing. The original gun was not very reliable (we discovered later that the tube tended to come off under heavy use) but was so revolutionary that it was adopted by (at the time private) escort detail of Silvio Berlusconi, not yet a politica figure.

Italian cops like me watched at the gun with envy as our Beretta M12 SMGs seemed little toys in comparison to that gun.

Interfor SA15 9mm Pistol - with Torkmag adapter

We have developed this SA15 9mm pistol utilizing a standard SAA lower , a 9mm Glock upper and a Torkmag adapter 9mm.

The Torkmag adapter can use Torkmag original magazines or Aftermarket Glock magazines of any kind with a slot added using the supplied cutting jig. You can convert any Glock magazine, even the cheapiest, to Torkmag adapater standard and use them in SA15 pistol and your gun as they remain restro compatible to Glock style handguns (the jig simply makes a cut a different area).

The Torkmag is of wonderful craftmanship aand once porperly set makes a rock solid 9mm gun.

Price is $950 including shipping to your FFL.

A comment from a 53 clone customer who bought the M53 clone in 12" depicted here below.

Simon-
I just made a payment for the additional magazines and the stock.
I am so happy with the result! 
I will send you back pictures of it being enjoyed!

G3 sniper clone test and little history of the rifle

The initial test fire of the our G3 sniper clone.

IFrst employed by the Italian Army in the ITALCON mission in Lebanon (1982), the G3 sniper was a byproducts of the lessons learned after the massacre of Munich in 1972, where it was learned that in urban environment and anti terrorism operations a fast second shot typical of the semiauto rifle is often a good tradeoff for the absolute precision typical of the bolt action rifle. 

THe is the presentation of our clone of that rifle, made available to the common shooter for a very reasonable price (much lower than the $14k of the original).

 

M53 clone test 5,56 cal.  in 12" barrel length

Another PPSH41 test but in 7.62 caliber version.

We test fire another PPSH41 in 7,62 Tokarev original caliber. This caliber is little hotter and more historically accurate. The good news is that you can change caliber simply swapping the barrel. Removal is easy just open the gun and remove a pin and slide the barrel out.

How to safely load a PPSH41 drum magazine

We have had some requests for PPSH41 rifles and we decided to make a video on how to load the drum magazine. It is not difficult but it is important that you always use your fingertips and never insert fingers in the spring mechanism as it can release and bite them. Use a tool to adjust the bullets position in the magazine.

Yugo M47 test fire 9mm rifle

We test fired our Yugo M47 9mm rifle at the lab bullet trap and at the range. Seems a PPSH but the system is more similar to the Beretta 34 SMG. Love it.

RPD semiauto rifle test fire with hammer system and binary trigger

We test fired our RPD semiauto build with hammer system and binary system. All OK. Ready for cleanup and finish.

FMK-3 rifle lab test fire

We have test fired the FMK3 semiauto build before heading to the range for more tests. We loved this gun and we are building more of these as we found the design way superior to the UZI and way more reliable. Thanks for watching

RPD MG semiauto clone rifle test fire.

MC51K prototype test fire , 4.5" barrel.

This is the test fire of our prototype MC51K Dragon based on a 4.5" barrel. The locking piece is modified to make the gun open on a short 4.5" barrel and the gun is powerful but very pleasant to shoot. 

Expected price is $1500-13000 due to increasted cost of parts. The gun is still in development as the end cap for the special extensible brace we have developed canmot hold the energy of the 7,62 Nato cartridge for long before cracking. Will probably have to revert to a traditional steel end cap with folding brace. On a 9mm would not be a problem but this gun is a juggernaut so we will have to use strong materials.

PPSh41 9mm rifle clone 16" barrel

This is our clone of the PPSh41 SMG, made in rifle version in 9mm. cal. 

We were surprised by the smoothe shooting of this build and the fidelity to the original , as the 16" barrrel is just barely longer than the original barrel and consents the use of the original stock.

Sterling MKIV build with Indianapolis Ordnance parts set (receiver and bolt)

M53 (HK%3 clone) test fire FULL AUTO registered pack

There is a story behind this movie. Mr. Matt Mink runs "Naples Gun and Ammo" a shop specialized in military firearms and clones and suppressors. He wanted to test one of our guns so he bought one from a customer (so it was not a special gun made for him), installed a full auto DLO registered sear and a OSS Helix 7.62QD Ti  suppressor and tested it. Only after his tests he contacted us and we are collaborating to a new series of roller lock gun made on his specifications. Mr. Mink was so kind to send us a movie of one of his test and was very impressed by the gun smooth workings.

100 Youtube subscribers ...and new THANK YOU VIDEO on how to build your semi auto Swedish K

How a G3 is made - original German movie

found this gem on Youtube . A vintage German movie on how the g3 is made with 1000s of operations. This will help to understand how difficult is to rebuild one of these guns. 

Swedish K M45 9mm. final test fire

Final test fire of our M/45 Swedish K built on order for a customer. This is the 3rd gun of this kind we have built this month, we had to stop due to scarcity of parts kit. They are practically unavailable anywhere by now. 

Pretty soo we will publish a complete build guide from a parts kit on this site.
