Special Interest Arms 07/C2

We are Integral Suppressor and caliber conversion specialists!
Please click the menu link at the left for details of each product.

I have now phased out taking orders for the De Lisle, 45-SC and other Enfield conversions.
May do some builds to sell from stock later, but no more custom build orders are being taken.
Decent actions are now hard to find at reasonable prices in my area.
Small critical parts are sometimes difficult to obtain causing delays.

I will have Enfield Picatinny rails in stock by the end of April, new production is nearly complete, please order now.

I have no more .45 kits in stock for sale as of 2/17/17.
Due to unrelenting demand I am making another run for April delivery
Please email to be put on the new pre-order list.
Kits only, no new builds at this time.

One last .50AE conversion still available in whatever configuration the buyer would like.

All other S.I.A. products are continuing.

Our Novem 9mm is the logical successor to the De Lisle and is built on a new action.

Standard 16" barrel Novem 9mm carbine.

Why make integral suppressors?*

We supply integral suppressors (Silencers) on several types of actions.
Making the suppressor integral to the action has several advantages.
1. Only one $200.00 tax stamp instead of the two required for a suppressor and Short Barrel Rifle (SBR).
2. More volume to reduce the shot report in a safer low pressure system.

3. Shorter overall length compared to a screw-on design.

4. Better balance as the added weight remains further back, closer to the balance point. 
5. The design is optimized for the one caliber since the suppressor will never be used for any other.

*Definition of an integral suppressor.

The suppressor tube is permanently attached to the barrel so that it's length counts for overall length per ATF regulations.

Why did we use the Enfield action for conversions?

Until fairly recently the Enfield actions had been relatively inexpensive and plentiful.
Their two-piece stocks design and wide magazine well made them easier to work with for conversions.
The No. 1 Mk. III Enfield is the only correct action for a proper De Lisle replica.

Machine guns and title one firearms for sale are listed on the Updates and Sales page.

Contact us

"Yahoo" mail is unreliable and usually not working for me as they are blocking all outgoing messages sent through my ISP.

If you are a Yahoo mail user please use another email provider so that I may respond promptly.

Yahoo is "a temporary issue" but keeps coming back, and there is no means to contact them directly about it!

"G-mail" should now be working again after changes to the SPAM filter.

My Email seems to have auto-deleted all messages I had saved for later contact regards back-order and suspended items. 

So you may want to recontact me regards De Lisle's, scope rails, etc.

 Shop visits are by appointment only as we do no local retail.
