Enfield .45 Carbine and kits.
Due to unrelenting demand I made a FINAL run of the the Enfield/De Lisle .45 conversion kits.
Selling kits or adapters ONLY at this time! 
Less than ten sets still available as of 11/26/16
No build service available from me at this time, maybe next year?
I do not have time to search for decent actions at reasonable prices.
Small critical parts have become more difficult for me to obtain.
Same price but I will not be supplying the magazine, easy for you to  order from Brownells.

In stock, for now.

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 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!
Barrel length 16.5". 

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 kits.

A little too complex for home builders as it requries TIG welding, we can add it to any kit for $50.00.
We need your old bolt head sent to us with your order for this upgrade.
