SIG Sauer ASP20 Gas-Piston Breakbarrel Air Rifle, Beech Stock

  • Gas-Piston
  • Breakbarrel
  • Weaver/Picatinny Rail

SIG Sauer breaks into the breakbarrel airgun market with the US made ASP20 Break Barrel Rifle, a suppressed single-shot, gas piston rifle ideal for backyard target shooting and taking down small game.

Available in .177 and .22 the ASP20 uses a gas piston powerplant that is specially calibrated to deliver its pellets downrange at optimal speeds for accuracy and energy.  The added benefit of this powerplant is the ability to shoot in colder weather without sacrificing power as you would with a spring-piston.  Each uses a Glidelite Cocking Mechanism to ensure that your cocking effort is a smooth and manageable 33 lbs.  In the .177 caliber, the ASP20 slings pellets at 1021 fps, and at 841 in .22 to dump 20 to 23 FPE into your targets.  This design is based on the notion that subsonic pellets will fire more accurately, a maxim that proves true time and time again among premium airguns.  Built for quiet backyard shooting, those powerful shots are all moderated by an integrated suppressor.   

Moving to the action, the ASP20 features an adjustable 2-stage Matchlite® Trigger, designed for smooth and consistent trigger pulls to aid in accurate shot placement. A proprietary drill-pinned Breech Wedge Lock System also aids in improved accuracy by perfectly lining up the action with the barrel.  A long Weaver/Picatinny rail awaits your choice of optics, and all of these features are set into an ergonomic black stained beech stock with excellent checkering on the grip and forend.  

All of these options culminate in a superior gas-piston breakbarrel air rifle that lives up to SIG’s legacy of crafting airguns with improved tech, quality build, and are a thrill to shoot.

Things I liked:

Incredibly accurate out to 65yds provided your scope is new. I go through 2 scopes for every tin of pellets.

Things I would have changed:

It should come with sights, because it destroys scopes in less than 1/2 tin of pellets.

What others should know:

Mine is a paper weight. Scopes fail in about 100-200 pellets. Airmax, Whiskey3, UTG it doesnt matter. Tried 3 different mounts same result. Buy 10 scopes with the lifetime warranty and rotate them out as they lose zero. This the only way to keep this rifle in use.

Things I liked:

Shoots like a dream right out of the box. The trigger takes a little getting used to, and I reduced mine slightly, but after that great groups out to 30 yards. It does take more effort to initially cock that my Beeman R9, but is much quieter to shoot.

Things I liked:

The SIG Sauer ASP20 is very accurate. Consistently shoots 1/2-inch groups, while resting on a bag, and even smaller at times, shows the rifle is more accurate than I am. Superior to my Chinese rifle from Walmart. Trigger is light and fires clean without creep, right from the factory. Beautiful dark wood grain with excellent textured grip. Cocking is very smooth and also comfortable due to the shape of the silencer. Safety position is easily visible and accessible from both sides, eliminates the frustration of other safeties. Worked well with all 5 pellet types I've tested so far on 0.177. My favorites are JSB Heavy Diabolo, H&N Baracuda Light and Crosman Ultra Magnum.

Things I would have changed:

The barrel came with light surface scratches. Visible when viewed closely.

    • Jeffrey from USA asked:

      I've heard that the Whiskey3 scope has been discontinued by SigSauer, implying that the package deal will now never occur. Can yo please confirm this?

        There is no package. Just the rifle .
