SIG Sauer ASP20 Reviews

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.

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.

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.

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.

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

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.

Shoots great with JSB 18g Nice balance

Needs to come with a sling.Gets heavy after while

Great rifle for the price

The ASP20 is a very accurate breakbarrel. I am new to the breakbarrel world, so I was concerned that I would be unable to develop a consistent hold. But after just 2 practice sessions, I started hitting the target with great consistency. Man is this rifle fun to shoot.

I wish Sig Sauer made a .25 caliber.

I mounted a SeeAll Open Sight because I do back yard shooting and I didn't want to mount a scope (at least not yet). I am very pleased with the both the ASP20 and the SeeAll sight.

This rifle is very powerful and accurate.It blasts right through 1/2 plywood that i paced off at 30 feet.I purchased this rifle without a scope and later fitted it with a Sig whiskey 3 scope. Im impressed with the accuracy of this rifle .The groups at 30 feet are dime sized.I will leave feedback after i try it at longer distances at the range.Another reason i purchased this rifle that it is made here in the united states. Im going to hunt squirrels with this gun in the fall.

I wouldnt change a thing.This is a high quality rifle

Some may not like the weight it is a bit on the heavy side. Im using this rifle to hunt small game.I bought the 22 cal.

Quality of build and accuracy. I have recently purchased 4 different springer (coil and gas) air rifles, the SIG ASP20 is the most accurate out of the box.

The stock is somewhat bulky.

The ease of closing the barrel upon cocking is more pleasurable.

Accuracy. Tight groups. Handsome rifle. Enough power .22 for efficient kills on squirrels. Balanced nice. Barrel and picatinney rail very true. Minor scope adjustments to dial it in. Trigger is awesome. 1st stage travel span was set a minimum out of the box. Easy break down to charge cylinder. Locks up solid. Awesome technology and design at the lock up. Gun is almost maintenance free. White lithium grease at the pivot points.

Make it lighter but then you would have to sacrifice something.

Well made

Make gun lighter

Not yet

Very accurate. Trigger is smooth, very little creep if any. Solid breech to barrel lock up. Quiet. Easy to break and charge piston. Balanced very well. Packaged nicely in a corrugated box with foam thats reusable. Pyramid puts it in an outer shipper for protection.

Its heavy.

easy to cock with plenty of power, trigger can be adjusted lower than you can want it.. accuracy is great with almost any pellet you put in it

its a little bit heavy with no eyelets to put a sling on it

i bought the .177 based off of i had to wait to get a .22... Over all i am very pleased with the .177.. it is accurate with almost any pellet you put in it..

Ambidextrous safety. very manageable weight. grip is very comfortable. quiet, very quiet. accuracy is excellent with an 18.4 gn pellet. we are able to maintain a very tight grouping at 30 yards. 1/2" using a red-dot optic. the 18.4 gn pellet is repeatable at 720 to 730 fps and they are hard hitting out to 50 yards. very entertaining gun to shoot especially at moderate distances when shooting metal, nice little ring. trigger adjustment resolved the little takeup it came with and now feels as good as anything else we shoot.

not much, the breaking action is stiff, and that is expected. but once you break it the cocking action is easy and feels solid. snaps back cleanly.

for inside 30 yard shots on small game I don't think I have seen a better platform.

Solid ergonomic synthetic stock, steel Picatinny rail, good groups, good materials, smooth operation.

SIG need to be sure to align the barrels with the receivers and rails. Better yet, just add an underlever and be done with it. Plastic trigger would probably look better quality if steel or aluminum.

Why the break ? There is really no good reason to have a break barrel airgun design, especially since almost everyone uses a scope – this means that the barrel moves relative to the receiver and scope mount. Why ask for trouble when an under-lever avoids the problem ? Just a hair of movement equates to quite a variance in shot placement at 25 yards. Given that SIG tend to make innovatively designed precision products using good materials, and they advertised this as having precision barrel alignment and repeatability, I decided to give it a try. I took great care mounting my favorite airgun proof scope, but when I went to zero it I found that at full scope elevation it still shot an inch low at 25 yards (shot great groups, just low). I measured the angle between the barrel axis and the receiver – it was almost half a degree out, with barrel pointing down. I emailed SIG with a detailed description of the problem and they sent me a shipping label. Two months later the rifle was returned with a message that they had test fired it with their equipment and it was OK (the test target showed it shooting low at 25 yards). The documentation indicated that the customer service people had not communicated my well documented problem to the technical assessment people. Everyone knows that if you install a scope with a greater range of adjustment then you will be able to get zeroed – but my view is that I should not have to use a specific scope with large adjustment range on a rifle that is advertised as being a new generation of break barrel with revolutionary precise alignment. I solved the problem by mounting a fixed 6x SWFA Super Sniper 30mm tube scope with 140 MOA of adjustment – somewhat limiting (scope and mounts cost more than the rifle). I don’t know how many ASP20 rifles are like this, perhaps most users get it zeroed and don’t realize, or don’t care, that their scope is maxed out on adjustment. The bottom line is that I would not give any other break barrel more than 2 stars. The SIG gets 3, but would have had 4+ stars had it been manufactured properly, and had the customer service/tech assessment been better performed. Points to SIG for at least being receptive, and paying shipping both ways. This rifle has a good solid ergonomic synthetic stock, an accurately welded on STEEL picatinny rail, is made from good materials, and is made in the USA. With a little practice SIG will have a market leading winner (it is already the leader in break barrels, despite the problem). For now, there are several good under lever designs out there, so why risk it. Why did SIG risk it – they should have just made this an underlever from the start, it could have been a world-beater.

It is a good as advertised. Quality is high. Built to last. If accuracy is the primary objective, consider this rifle.

Nothing

Trigger adjusted to 2 1/4 pounds.

Impressive crisp trigger out the box. 1 lb. 10 oz. Phenomenally accurate with a variety of pellets. 1/4" groups at 25 yards. Smooth cocking, but not easy for me unless I use both hands. Picatinny rail is a nice touch instead of a dovetail. Power level seems to be perfect for the 22 caliber, 800+ fps with medium weight pellets. Really likes the H&N Hunter Extreme pellets.

Not a thing. Sig Sauer nailed it with this one.

Make sure your scope and mounts can handle the sharp snap of the recoil action. Buy premium (pro) mounts. The guns seem to be in short supply, so be prepared to preorder. Well worth the wait, though.

First, the packaging! SIG did it right...the gun arrived in a heavy box, with foam cut out to actually fit and protect the gun. -Hefty, Beefy, Stout are all words I would use to describe this gun..and I like them all. -The barrel "lock up".....simple concept, executed in an outstanding manner, and I believe its a major reason this gun is so accurate. -ACCURATE!! -Surprisingly good trigger. Out of box it is perfect for me. -The welded on rail! Gosh I wish all air rifle makers did this. -The stock is design/built so I can actually rest my cheek where is should be, without "reaching" to see through the scope.

-Safety...just awkward all the way around.

When this gun arrived, I checked it over, and everything was tight from the factory, then clean it. The bore was surprisingly clean. After cleaning the bore with goo-gone, I used a bore mop slathered in Mothers Caranuba cleaner wax in the bore, let it sit for a couple of mins then followed it with a couple of clean patches. Some might think I'm nuts, but I believe doing this aids in a guns accuracy. For years I've done this to my powder guns with increased accuracy.....and it seems to work in air gun too. (check the pics) To date this is the best piston gun I have seen/fired. SIG did it right, and for me this gun is certainly a keeper!

Shoots great, handles well but hard to cock. Enjoy shooting it.

I enjoy shooting an accurate rifle and this is one for sure! My son sighted it to zero on the mil-dot just below the crosshair and as long as you do your part, that is exactly where the pellet goes. We used Crosman Premier hunting pellets and H&N sniper pellets and the zero was the same even though the sniper pellets were a bit heavier than the Crosman pellets. The trigger works flawlessly and it breaks really crisp. I'm not sure of the pull since I don't have a gauge to check it with, but it is very light. I would guess about 2 to 2.5 lbs. Overall, a very nice gun and I am very pleased with it. SIG did an excellent job with this rifle!

This is not a complaint but it is a very heavy rifle. It is even heavier than my son's 308 that he hunts with.

My son said that the cocking effort is a little on the heavy side and it is, but it isn't nearly as heavy as some other magnum power air rifles. If that is an issue for you I would say to try one out if you can before you buy it.

The quality of the gun is amazing. My son, Jordan, helped me to mount the scope that I bought for it and even though I haven't had a chance to sight it in yet, the first shot only landed about five inches below my aim point. I am looking forward to finishing this review later. I am very impressed with this rifle and the folks at Pyramid Air are great. I will come back and update when I get the scope sighted in properly. Thank you so much!

Nothing!

If you are looking for a quality air rifle, SIG-SAUER has you covered hands down.

This rifle is very well built and of high quality, an excellent value for the money spent, and is extremely accurate! I highly recommend this rifle!

Nothing, this is a great rifle!

Purchased the Asp20 in .22 with whiskey3 scope.Did a lot of research on other high end break barrels and decided on this rifle.Couldn't be more happier.I can't put it down.Very powerful and scary accurate.The scope is truly amazing.I purchased a lazer range finder to use to it's full potential.In some hunting situations hold over with the mil dots work best.But when you can range your target and know exactly how far it is,and be able to dial the scope to that range and hold dead on...Truly amazing.
