Special Interest Arms - Enfield Conversions

Enfield .45 Carbine and kits.
I have phased out the De Lisle, 45-SC and other Enfield conversions.
Decent actions are now hard to find at reasonable prices.
Small critical parts are difficult to obtain.

I have used up the magazine adapters I had on hand.
.45 conversions are done unless I can find a way to make them more easily.


I am leaving this page up as a reference archive.

Our kit is clearly superior to any previous Enfield .45acp conversion set.
We use McGowen Precision® premium barrels and our improved design magazine adapter.

Our regular kit or build incorporates 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 our magazine release lever, no more cutting your stock or trigger guard!
Please specify barrel length with your order, 16.5"-18". 

As of 2/15/16 our .45 conversions kits are no longer available unless we decide to make more adapters late in the year.


Still available for 2016

Optional barrel nut to accept AR-15 type free-float or rail hand guards.
$25.00 clearance sale.

We have perfected an improved ejection system which is not visible from the outside for all .45 variants we assemble.

A little too complex for home builders, we can add it to any kit for $50.00.
We need your old bolt head for this upgrade.
