Near-Replica of the De Lisle Silent Carbine.

Production of our version of the .45 De Lisle Silent Carbine has begun.
We have obtained and registered several additional No. 1 Mk. III actions for additional builds.
Retail price is $2,250.
Dealer pricing available.

Ours is not an "Exact" replica as it uses our standard .45 conversion components.
This means it accepts unmodified M-1911 type magazines and is much simpler and stronger than an original De Lisle.
The tooling is more complex than our earlier 45-SC model due to the off-set bore line.
Except for the magazine adapter the appearance is very faithful to an original.
The larger picture below is the final prototype, incorporating our new fore-end.
The charger guide has been removed as was done to most originals.

We are currently using original type baffles in stainless steel, a mono-core design will be available soon for those who prefer it.
 

The bolt remains full length, and the 16" silencer tube is integral to the action so that only one NFA tax is required.
Feed and extraction are vastly improved over the original, and the barrels chamber is fully supported in the receiver.
We DO put a black Delrin® insert in the bolt handle to prevent it from clicking when closing the action!


Test firing on several occasions confirms that the design is very quiet and very accurate.
The sound pulse is very short with no following hiss. We have confirmed that a shot cannot be heard at fifty yards!

We can do a separate SBR and Silencer section that do come apart on request. $100.00 additional cost, buyer will require two NFA stamps.
We have had a few request for an "Exact" replica.  Sorry, but we have no desire to replicate the flaws of the original design.


Please email for an NFA item order form.
Our order form for non-NFA items is at the bottom of the Enfield Conversions page.

Our .45-SC, inspired by the W.W. II De Lisle, but built on a No. 4 action using a concentric tube and modern "M" baffles. From $1,250
We are still producing our integrally suppressed .45-SC.
Very quite, with standard 230 gr. ammunition they sound like a BB gun, high velocity Remington "Golden Saber" 180 gr. sound like an air rifle.
They are available with wood or a black synthetic stock.    
On F3's in Nevada, prices begin at $1,250.00 and NFA tax.
We always have a few of these in process, we use a sinker EDM to port between the barrel lands for perfect burr free holes.

45-SC with all options.

To simplify production all synthetic stock 45-SC's will now have the fore-end cut as pictured above.
A solid AR-15 type free-float cover will be standard, a rail type is optional.

A long .45-SC video.

The close-up video has some errors in the dialog but does an excellent job of displaying the gun and it's features. 
None of the guns in these videos are a true De Lisle replica, they are all our standard 45-SC's.
They are inspired by the De Lisle but are updated with modern technology, built on a No. 4 action.

Our true De Lisle replica is now being delivered to customers, built on No. 1 actions as original.

 
The 7.62x39 "K" version of our Silent Carbine is limited to only three units.
One has been sold, and I am keeping one for myself!
Due to the round normally being supersonic it is not as quiet as the .45-SC or De Lisle, but is "hearing safe".

Sub-Sonic ammunition is commercially available, allowing 300 BLK level performance. 
One only available at $1,400.00.
