Sorry, there is a temporay back log on adapters.
We got barrels in, now we have to make more adapters.

Our kit is superior to any previous Enfield .45acp conversion set.
We use Montana RiflemanĘ premium barrels and our improved design.
We incorporate a spring loaded ejector stud, our design ejects spent brass reliably.
 
Our .45 magazine adapter holds the magazine exactly in it's proper location.
  Note the location of the magazine release lever, no more cutting your stock or trigger guard!

Due to strong demand we doubled our production for this run of kits.
Please specify barrel length with your order, 16.5"-18".

We assemble complete guns for only $100.00 on your action.
Please copy and print our order form for inclusion with your payment.

Build manual.

The Enfield .45 is also available with an integral suppressor!
The suppressor is integral to the gun, so there is only one NFA tax.

New products for 2010 include an integrally suppressed .45 Carbine inspired by the classic W.W. II "De Lisle".

We can build non suppressed "Delisle" near replicas for reenactment and residents of non NFA states.
     

 Enfield to CAR-15 collapsing stock conversion adapter, only six available as of 8/6/10.
They seem to be fairly popular, we are researching a less expensive manufacturing method. 
They are currently made from billet on CNC equipment, then mil-spec Black hard-anodized. 
Price is $200.00 each for the adapter and retaining bolt.
A CAR-15 stock and pistol grip is NOT included.

An example of what can be done with the CAR-Enfield stock adapter and some imagination!



Enfield "K" in 7.62x39!
By Special Interest Arms.

The classic #4 & #5 Enfield's have been updated to shoot the inexpensive and accurate 7.62x39 cartridge!

The converted gun uses interchangeable 5 and 10 round single stack AK-47 detachable magazines!

No modifications to the original Enfield receiver are required.

"K" for Kurtz*, the 7.62x39 round uses the same .311 diameter bullet as the original .303 British caliber, but with a lighter 125 gr. bullet, in a shorter cartridge case.

Ideal for youth, ladies and anyone else desiring a .30 cal. rifle with light recoil!

Inexpensive to shoot, plinking ammunition is typically only about $5.00-$8.00 a box!

Soft point hunting ammunition is readily available!

Reliable bolt action design, conserves on ammunition cost and promotes accuracy!

All Enfield #4 rifle accessories remain fully compatible with the new Enfield "K"!

The bolt action and heavier barrel appear to greatly enhance accuracy over that to be expected from SKS or AK-47 type rifles!

The new complete "K" kit price is $350.00
