S.I.A. De Lisle Silent Carbine.

I have ceased building De Lisle's beyond completion of current orders.

I have phased out all Enfield conversion builds.
Decent actions are now hard to find at reasonable prices.
Small critical parts have become difficult to obtain.
Many basic components still available for F1 or SOT builds.


 De Lisle's may be available in limited production from spring of 2018.
I am looking into finding another SOT interested in taking them over.
You may send an email to be put on a waiting list for notification as more units become available.
I am certain that supply will remain limited due the amount of hand fitting required.

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

De Lisle Silent Carbine is now out of production until another assembler is found.


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

Ours was not an "Exact" replica as it uses 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!

Last builds are now a separate SBR and Silencer section that come apart as original.
Buyers 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.
