Sicario is the new and improved version of our QAS line of integral silencers for 2017. We went back to the CAD program and after 28 monocore designs emerged a PATENT PENDING 2 piece quick detach integral that is not only quieter than its predecessor but comes apart for cleaning in about 30 seconds. No more tedious parts to manage! Although the end cap is broached for an allen wrench like the remainder of our designs, there is no allen wrench required as you can use the factory magazine to disassemble the entire suppressor. The monocore is constructed from 2024T351 aluminum and TYPE III anodized for a lifetime of use. There is also a stainless insert in the rear of it that will not fatigue. Alignment on your weapon is easy with our new Patent Pending “fast attach 28” thread mount system. Fluting is in now included on all silencers at no additional cost to you.  

YES, Your current silenced MKI, II, III™, or 22/45™ can be upgraded to this awesome design! Please email us today.  

Price is for silencer on your pistol.  Add a SS MK IV™ for additional charge.


What is the SIC adapter? I dont understand what is does? Is this what makes the Sicario a multi use Silencer?
YES! Not only is the Sicario the worlds best Integral silencer, it is the only Multi platform host. The threadless tube design with the SIC adapter allows you to remove your Sicario from its host MKIV™ or 22/45 platform and make it a screw on .22 rimfire silencer that will fit any .22 host that is threaded 1/2 x 28tpi.

Why is the barrel ported?
  The barrel is ported so that the majority of bulk high velocity ammunition will be 1000 fps. Most bulk ammunition chronographs between 25 and 110 fps which make it challenging to offer one model that works great with everything. CCI ammunition is the most consistent based on our testing and it only varies 2-15 fps making it the ideal choice for the Sicario. The porting holes are very small which allow CCI standard velocity to still reliably function.

Can the porting be eliminated?
  Yes, In Services section on we offer a port blocking option so that the user can make the decision based on his or her needs and ammunition requirements, however it will increase the overall sound reduction by more than 5db which is far below hearing safe @ 119db 

Why is there 3 cuts on the end of the barrel?
   Before the Sicario, Integrals have always been a pain to disassemble and assemble. Mainly, during assembly, trying to get the barrel nut screwed on inside of the tube and on the barrel at the same time. The Patent Pending Sicario Monocore has the threads relieved on the inside of the monocore threads so that, much like the popular 3 lug mounting systems, you can drop the core in the tube directly over the relief portion on the barrel threads, find the sweet spot, and install it effortlessly. 

Do you recrown the barrel?
  We crown the barrel to an 11 degree target crown which enhances the accuracy from Ruger.

What threads are on the barrel and the monocore? 
  1/2 x 28 tpi 2A threads. All of our threads are checked with factory calibrated Go and NOGO gauges.

Do you shorten the factory barrel? 
   Yes, we shorten it 1", the factory barrel is 5.5" long and the Sicario barrel is 4.5". Due to the tension we put on this barrel with the Sicario, it makes an average shooting handgun more accurate.

Do you make the Sicario Shorter than 8"?
  NO! The Sicario is 22 years of experience poured into one perfect Integral Silencer. There were dozens of cores and barrel lengths as well as tube lengths tested during this upgrade and the 8" version with this barrel length, porting, crown and overall length are what sets it apart from the competition. Not only is it the only multi use integral, the quietest, easiest to use and best looking silencer on the market, it is far more affordable than the competition.

Can I buy just the upper receiver and Sicario silencer from TBA?
No, all of our Sicario silencers are built on factory Ruger MK IVs (TM? wtf) If you want to buy one from us you have to purchase the complete weapon from us our send us your upper receiver for the install.
