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 30 days and we are working weekends to keep the production rate. Our best customers have ordered about 10-12 different models/versions of firearms and having so many returning customers 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.

After the Military Arms Channel and Small Arms Solutions videos featuring our guns, we have received a lot of inquiries about our AR 70/90 builds, so we decided to post some information about them.

To have an AR70/90 clone built you need the following:

A complete AR70/90 parts kit (some parts but not complete kits can be found at Apex Gun parts site).  Our sources say that all of these rifles have been sent to Ukraine within the current military aid program so for the moment we are not expecting any from Italy. They will be back in parts kits one day but won't be tomorrow. Right now the best venue is on Gunbroker.

Once you have a parts kit you will neet a Troy Ess (essbros) receiver and barrel.

Barrels are very good but the 80% receivers are absolutely gorgeous. There are other solution (I have some flats) but the Ess receiver is way better than anything else.

Consider the Ess kit to be around $800 + shipping if sourced from us (more on Gunbroker) .

RIght now Troy Ess seems to have not many in stock so if you have a parts kit buy a set from him right now. 

And yes we do build AR70 series I too (and STGW 57, AKs, ARs , HKs etc.) but you will still need a parts kit (super super rare).

After 6 years if trying we have finally made it. We have made an RPD lower based on the AR15 system. 

This gun uses Ar15 parts and an AR10 tube and spring (for max energy) and finally we have found a material capable of withstanding the RPD energy and recoil. This is the Navy Seals 16" version and with this system is more similar to a SAW than a RPD. The original RPD stock can be used too, using a different design.

This time we wanted to make an M203 clone using a 37 mm. launcher equipped with Picatinny handguard. While mounting a Launcher on a rifle is very easy using the Picatinny, we wanted to make something really similar to the original M203. 

We designed an M203 handguard clone from a very hard to find original and we equipped it with a Picatinny rail underside.

With this handguard it is possibile to mount any launcher with a Picatinny clam on top (almost all available ahave one) and install it under the hadguard making a credible M203 system look alike. 

All cases and projectiles used are 3d printed too.

37 mm. launcher have been deemed signal launchers by the Coast Guard and are considered non firearms (respecting certain conditions).

We have been honored by Internet personality MISHACO to test and evaluate two of our AR70/90 builds. The builds were regularly paid full price so the good the bad and the ugly will be all there. We thank Mr. MISHACO for the great opportunity he has given us introducing one of our most known builds to his audience.

This is the presentation and test fire of our AR15 magazine adapter for the SIG 550 faily (551-552-553). The system is composed of one adapter which drops in the SIG rifle. The Lancer AWM magazine works "as is" while the MAGPUL Gen 2 or 3 magazine you must use the provided overtravel guard which slides on the magazine body. Other magazine model (metal etc. are NOT supported due to the variety of dimensions out there). Also each magazine will need a slot cut in the back as by jig on the side of the over travel guard provided with the kit.

This adapter is designed for steel lowers only. Aluminum lowers have different dimensions. If you have an aluminum lower see our Aluminum lower model up the page. 

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.

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.

I learned a lot even before moving to the US and being honored of meeting him in person..

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.

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.

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.

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 $1300-1500 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.
