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

  • Gas-Piston
  • Breakbarrel
  • Weaver/Picatinny Rail
  • Black Stained Beech Stock
  • Integrated Suppressor
  • 2-Stage Adjustable MatchLite® Trigger, 2.5-4 lbs trigger pull
  • GlideLite™ Cocking Mechanism
  • Wedge Lock Breech System eliminates barrel droop


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: Came very well packaged. It is a beautiful gun. I received my gun Friday and installed a scope and got the crony out Saturday and started to shoot,16 grain air arms shot at 785 to 805 predator GTO 11.75 grain shot between 945 and 955 H&N field target green 9.85 shot 1048 to 1055 all the pellets were shot in 10 shot groups. After 70 shots accuracy really came in I started to shoot for real 10 shots in 1/4 by 3/8 with one flyer second shot next group less than 1/4 by 1/4 from 21 yards very impressive. the trigger out of the box is hands down the best air rifle trigger I have tried by far really a 2 stage trigger that works perfect very important for precision shooting. All the pellets I shot were very accurate I used the air arms for the price point only they were no more accurate than the other 2 I tried so far the gun has lived up to the hype.

Things I would have changed: The color of the stock is really dark almost black I prefer a lighter color of wood. The barrel is very hard to break after a hundred shots I could feel it in my hands I have 2 mod 125 Hatsons and they are much easier to break by far I hope It gets a little lighter with time. The rifle is a bit heavy but not to bad the gun is easy to cock one its broken open

What others should know: I cant wait to shoot the gun some more and try some differ pellets, next time I will try 35 and 50 yards and see how it shoots, by the way best accuracy was off a rest without my hand under the gun. the gun does have a strong recoil it keeps knocking off the flip lens cover on the eye piece, it should settle down with a few more hundred shots or so.

Things I liked: Very sturdy and fully finished to a professional grade. Quite a "badass" piece. Very quiet and though the 22 cal packs a hearty punch, the recoil is not bad at all. Part of the reason the recoil is so muted I believe is the heaviness of the burly and solid, heavy duty steel construction and beech stock (which is certainly easy on the eyes). Now, YES, the truth is that it is quite heavy........ my healthy 9 year old can not yet comfortably support it when free standing, but I would rather he grow into it than toss around some under powered, foreign made, synthetic...... toy...... This is not a toy! Do you want to piss a squirrel off? Or do you want to call "LIGHTS OUT" and send it flying off of it's branch with 23 ft/lbs........ If there is any humane way to take an animal it's with a precise, clean, and powerful head shot. One and done baby!!!

Things I would have changed: Again, I wouldn't change it because it is (I believe a byproduct of quality construction) but this is quite heavy. Still new to this gun so it will take some use to vet quality of the inner components. What good is an airgun if it don't fire? Well, only time will tell if the interior is as well built as the exterior. If the air spring is built as well as the outside (which I suspect and hope it is) then I've got three thumbs up for this one. Fires great now and if it stays this way I'll be very very pleased.

Things I liked: I just got this on Sunday and have only been able to shoot it a few times and havent been able to zero in the scope yet due to daylight/work but is such a huge step up from my Titan .22 which for $100 wasnt bad but this has crazy power and is super smooth and has less recoil. I am hoping that Sig or PA will offer those of us that shelled out the money to be the guinea pigs with this gun a coupon towards the whisky scope they are advertising on the combo as I would have bought it if it was available. I havent found it difficult to cock or break the barrel as someone had complained but I have had to use another pellet to seat the one I am shooting as I dont have a pellet seater...I will make one this weekend.

Things I would have changed: I wish it had a place to attach a strap

What others should know: Its a few inches longer than my Benjamin abd other Crosman.

  • Charles from USA asked:

    Is there a way to attach a sling to this rifle ?

  • Randall from USA asked:

    Is anyone having trouble opening the breech. Absolutely awesome rifle but never had one this hard to open. Bruised palms and all i still love this rifle.

    • Tyler from USA:

      I found the lock up on mine was extremely tight out of the box. It loosened up a bit over time, but it's pretty tight still. Can't say I bruised my palms or anything though

  • Edward from USA asked:

    Is the barrel threaded or is the moderator exchangeable, cleanable replaceable removable etc. Can you use the moderator as a holding point while cocking ?

    • Tyler from USA:

      The moderator is fixed. Cannot be removed. Yes, you can use it as your holding point when cocking the rifle
