S.I.A. De Lisle Silent Carbine.

De Lisle conversions no longer available to order, may do a few to sell from stock in 2017.

We have ceased building De Lisle's to order.
We may do a few next year to sell from stock as built to our own specification.
The De Lisle may become a two-stamp "Mk. II" version with a new baffle system and Ti tube.
If I do this the new Mk. II De Lisle price will be $3,500
Current standard De Lisle now $2,500 when available.

You may send an email to be put on our waiting list for notification if more units become available.

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

Due to incessant demand I am making one last FINAL short run of .45 adapters.

So a few more De Lisle's may be available in 2017.

Since this page is popular I will leave it up primarily as a reference archive.

De Lisle Silent Carbine is now out of production.

No Silencer components may be sold in kit form per BATFE regulations.

Ours was not an "Exact" replica as it used our standard .45 conversion components.
It uses unmodified M-1911 type magazines and is much simpler and stronger than an original De Lisle.
Except for the magazine adapter the appearance is very faithful to an original.
The charger guide is usually removed as was done to most originals.
If scope mounting is planned the charger guide needs to be retained.
We are currently using original type baffles in stainless steel, a mono-core design is planned 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 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 as original 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 war-time design.
