Hard Air Magazine Test Conclusions

The LCS Air Arms SK-19 is powerful, accurate and fast-shooting. This combination of benefits is one that's hugely attractive to many airgunners.

Cycling is excellent with a wide range of pellets. In spite of the selective fire capability, you'll notice that there's no mention in this review of jams. That's because there were none...

This all makes the SK-19 an easy HAM Gold Award winner!

So is the SK-19 a perfect airgun? Well, it's very expensive and rather loud. You'll also need to wait to buy one. But the fixed magazine is probably the only real weak point. With an interchangeable magazine capability it would be close to perfection for many shooters.

VALUE FOR MONEY

The LCS Air Arms SK-19 is the first model produced by this new, North Carolina-based company. Priced at $2,089.00 it definitely falls within the high end of the PCP market, but provides unique features found on few other airguns.

Its claim to fame is the ability to switch from semi-automatic to automatic shooting with the flip of a lever. There’s also a fully shrouded and moderated barrel, picatinny scope rail and extended accessory rail. Optional 480cc or 580cc carbon fiber bottles and aftermarket accessories allow considerable scope for customization.

So why would one consider owning and shooting a LCS Air Arms SK-19? We have little doubt that owning this rifle will rank high on the “fun factor” for what is currently available in the PCP market.

Although there are several other semi-automatic models on the market today, we couldn’t help but notice the accuracy that the factory installed Lothar-Walther barrel provided. Then we have the fully automatic feature that takes the SK-19 to a new level of fun in the precision airgun market.

The LCS Air Arms SK-19 provides for both fun at the range and utility in the field.

SPEED AND ACCURACY

HAM was provided with a .22 caliber SK-19 model for testing. The SK-19 proved to be an extremely fast shooting PCP rifle. In testing the velocity easily surpassed the speed of sound hitting 1,307 FPS with the 10.3 Grain H&N Field Target Trophy Green pellets.

Accuracy at 10 yards was excellent with all but three pellet groups. The least of which were the 9.56 Grain H&N Field Target Green, the 11.9 Grain RWS Hobby and 14.3 Grain Crosman Premier HP. Although these still produced 10 shot groups consisting of essentially a single ragged hole.

Speed  dropped to an average of 900 FPS with the 25.39 Grain JSB Jumbo Monster Redesigned pellets. At 900 FPS, the LCS SK-19 was dumping 45.68 Ft/Lbs of energy at the muzzle. In HAM testing this was also where it was most accurate at distance (see targets below).

Of course this wouldn’t be a HAM review if it wasn’t through. So Chad also tested the accuracy of the LCS Air Arms SK-19 on Full Automatic at 25 yards using it’s favorite pellets.

Not having tested or shot many fully automatic pellet rifles, this did take a bit of learning for the optimal hold.

However once learned, the SK-19 rewarded us with accuracy. Dumping a full 19 round magazine in under three seconds it produced one ragged hole just barely larger than the size of a nickel at 25 yards. HAM Tester Chad Kentner wasn’t able to wipe the smile of his face! (Hey it’s tough being a HAM tester!).

Of course, we were expecting accuracy to be a strong suit for the SK-19. This expectation was placed on previous experience and the fact that LCS fits its air rifles with German Lothar Walther barrels. The SK-19 tested by HAM certainly did not disappoint…

Wow! That’s outstanding accuracy for a 19-shot group on full auto. The entire group would be covered by a Quarter. Great shooting, Chad!

Chad then moved back to 50 Yards for 10 further shots with the Redesigned Jumbo Monsters. Again, very nice shooting!

TRIGGER AND COCKING EFFORT

The trigger weight of the LCS Air Arms SK-19 tested by HAM averaged 15.6 Ounces.

The setup of the trigger is a nicely curved and adjustable trigger blade. Just like you expect to find on high end precision air rifles like this one!

Pulling back, the trigger feels different than one might expect. The wall of the second stage isn’t easily discernible, nor is there a crisp breaking point. One might say it feels a little springy. After some use, the trigger was learnable and we were still able to provide a high level of accuracy.

Given that this is a PCP with the ability of Fully Automatic functions, HAM tester Chad Kentner doesn’t necessarily feel that a lighter or more crisp trigger would be appropriate for such an airgun for safety reasons.

The latest version – as tested by HAM – does have some trigger adjustment capability. However this is limited, as would be expected for a selective-fire airgun.

The effort to cock the LCS Air Arms SK-19 is –  in a word – “none.” Once you load your 19 round magazine, flip the cover down and take the safety off you are ready to roll. For the airgun hunter and pester, this is a highly coveted option for the quick follow up shot!

Of course, this is also a benefit in any type of speed competition as well – like Speed Silhouette – at least until after shot 19 when the magazine needs to be re-loaded.

 

COMPARISON TO MAKERS CLAIMS

LCS Air Arms makes limited marketing claims about the .22 caliber SK-19 fully automatic air rifle.

LCS Air Arms does state up to 80 consistent shots per 480cc fill. At the HAM testing facility we were able to increase that to just under 90 consistent shots using the 14.3 Grain Crosman Hollowpoint test pellets.

On the website there is also a graphic showing Airguns of Arizona’s test results using what they call “Max Power” and at a lower setting of 40 Ft/Lbs of energy. Our factory-tuned test model produced a maximum of 45.68 Ft/Lbs of Muzzle Energy using the heavy Jumbo Monsters.

 

CONSISTENCY

The LCS Air Arms SK-19 was tested for 94 shots over the chronograph and displayed consistency one might expect with a regulated air rifle. The last 6 shots started to show the rifle coming off the regulator so we will look at the consistency of the first 88 shots.

Over these 88 shots, the SK-19 had an average standard deviation of just 9.0 FPS. This means that you have plenty of consistency for a day of pesting or hunting in the field using the semi-automatic function.

You should note that flipping the switch to fully automatic will continue to provide accuracy (see fully automatic test target), but you will need to quickly refill after 4.5 magazines of fast action fun.

The average Standard Deviation for the standard HAM “fast .22” pellet suite was just 5.45 FPS. The lowest was just 2.5 FPS with the 21.14 Grain H&N Baracuda Match pellets. This is about the lowest Standard Deviation we’ve ever seen in testing.

Note also that the LCS Air Arms SK-19 tested by HAM demonstrated very good or better accuracy with five out of the eight HAM test pellets. So it cannot be accused of being “pellet picky”.

 

NOISE LEVEL

For some the fun factor of the SK-19 will outweigh the noise. Although the air rifle is fitted with a shroud and factory moderator we would not consider this to be a “backyard friendly” plinker.

When using lighter pellets that will easily exceed the sound barrier a sharp crack can be heard. HAM Tester Chad Kentner described this as “sounding like the crack of a .22 long rifle.” On the other hand that sound is settled when using the SK-19 with heavier – and generally more accurate – pellets.

Shooting the LCS Air Arms SK-19, the shooter can also hear a slight “pop” with your ear over the action as the air rushes through the system. Quieter than a rimfire for sure, but still louder than other high end PCPs on the market today.

It is possible to mount a 0dB – for example – silencer on the SK-19, however you’ll need an adapter to do this and the overall length will be increased accordingly.

 

SIGHTS AND SCOPE

The LCS Air Arms SK-19 comes with a Picatinny rail for your scope. This is made out of high grade aluminum and is mounted to the top of the rifle’s action. However with some scope and human eye combinations, it could be just a few teeth longer for perfection.

The shooter will notice that the Picatinny rails are elevated. In our testing and mounting of the Aztec Emerald 3-18×50 scope, this elevated rail aligned perfectly with the shooter’s eye. HAM Tester Chad Kentner found no need to resort to a riser, although he did employ high rings.

 

SHOOTABILITY

When shooting the LCS Air Arms SK-19, HAM Tester Chad Kentner was pleased with how it handled and shouldered. The accessory rail allowed for a convenient nonslip service for the forehand when shooting off hand as well as a stable platform to mount a bipod on.

Coming in at 10 Lbs 1 Oz with our Aztec Optics and sidewheel mounted and 35 inches in length. We found the SK-19 rifle to be well balanced and the AR-15 style was maneuverable in the field as well.

It was brought to the attention of HAM that the model tested is considered as the second generation of the SK-19. One of the upgrades that was made to the platform is the aforementioned accessory rail. It has been beefed up to provide less flex and for stability than the first generation.

HAM Tester Chad Kentner found the loading to be a little cumbersome at times. With the magazine not being removable, it made for slow loading of pellets after a fast and furious round of automatic fire. You will need to manually rotate the magazine after loading 4-5 pellets. Our tester just wished the fun didn’t have to stop and that he could immediately go right into another 19 rounds!

During testing we found the switch between semi and fully automatic was well located and easy to switch between on the fly.

Regulator set pressure, power level and rate of fire are all adjustable on the SK-19. However, the HAM Team recommends leaving all of these controls exactly where they are set by the factory. At least until you’re very familiar with the gun. Fine tuning for a specific pellet is quite easy. Large adjustments are unlikely to improve performance but you could possibly make things worse if you’re not careful!

Filling the LCS Air Arms SK-19 with air is just about as easy as it gets in the PCP market. There are no extra fill adapters or bottles to be removed. Instead the shooter simply needs a female quick disconnect on their tank setup.

Your fill assembly will then easily and quickly attach to the male quick disconnect on the side of the rifle. It’s situated immediately behind the tank on the opposite side of the gun from this photograph. This is a great design as you will certainly be filling the tank on a regular basis.

 

APPEARANCE AND FINISH

The LCS Air Arms SK-19 shows it’s true tactical roots found in firearms like AR-15 designs. The carbon fiber shroud and moderator give a slick semi custom look that many airgunners enjoy. They even went as far as designing cooling holes around the barrel to further the SK-19’s tactical appeal.

The glimmers of silver add a nice touch of class to the rear of the rifle. These highlights also standout as the parts of the rifle that are most often used by the shooter for loading and adjusting the rifle.

Speaking of the back of the rifle, it should be noted that the cheek piece and the coverings of the rear of the barrel are made of polymer. These being flat black in color they blend in well. They also provide a little warmth compared to the cold hard feeling of aluminum on one’s face when shooting some other bullpups.

The two gauges (pressure and regulator pressure) were easily readable by our tester and their position on the rifle didn’t interfere with the usability in the least.

 

BUYING AND OWNING

The SK-19 is available through Airguns of Arizona and Precision Airgun Distribution dealers across the USA. But demand is so high that there’s a constant backlog of orders! The best way to order is to place a deposit with AoA. This reserves your place and they’ll contact you as soon as your gun is available to ship to you.

You will want to ensure that you have a ready supply of air on hand as the LCS Air Arms SK-19 will absolutely use it! You may want to consider upgrading to the larger 580cc bottle or even a twin bottle setup that is available as an aftermarket part. A hand pump with this rifle just wouldn’t be fun.

Finally you will want to take note of and fully read the owner’s manual. There are some little tricks to loading and using the rifle that you will want to be aware of before taking the SK-19 to the range for the first time.

The manual is well-illustrated throughout. It’s in English only.

Otherwise this beautifully designed as well as fun, accurate and useful air rifle will provide the owner with many fun trips to the range.

All LCS SK-19 air rifles are warranted to the retail consumer for three years from date of purchase. This warranty applies to the original retail customer. The warranty covers faulty workmanship and defective materials. Proof of purchase is required in the unlikely event that warranty support is required.
