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 fps 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 Breach 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 synthetic stock with 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 innovative technology and quality construction that deliver hours of shooting fun.

Things I liked:

Accurracy! 5 shot 1/4" to 3/8" groups at 25 yds. with JSB heavies. The trigger is excellent for a magnum class piston air rifle. The synthetic stock is set up for quick detachable sling swivels. A really nice touch.

Things I would have changed:

I would like to have the butt stock with a straight belly rather than the cut out. It would be easier to use on bench rest bags. The advantage to the cut out is weight reduction and since this is ment to be a walk around gun the lower weight is a good thing.

What others should know:

I tested several different pellets from JSB and H&N, both heavies and midweights. They all shot well and they all had a 33yd. trajectory curve that was so close that they can used interchangeably in the field. Zeros are at 25 and 33 yards. This is my second Asp20 rifle and they both shoot equally well.

Things I liked:

The accurracy! This is my second Asp20, and both of them are equally accurate. 25yd. groups of 1/4 to 5/16", and 50yd groups of 3/4" and often less. This is with JSB .177 10.64gr. heavies in both guns. Just amazing! Very smooth shooting during recoil as well, no vibrations evident. Triggers are quite acceptable for a field gun as well, quite nice actually.

Things I would have changed:

I've shot the first gun for two-ish years now and I'm very well satisfied with the gun overall.

What others should know:

I was asked to clean the Rockchucks out of a friends pasture. None of my shots were over 25yds. All of them were head shots and all of them were clean instant kills. The pellet, JSB heavies .177, all passed thru without trouble. I also use this gun for our local Field Target matches with great success.
