SKU:
In Stock
$ 299.99



Total: $359.99

Type: Pellet Rifle
Manufacturer: Sig Sauer ASP
Model: Sig Sauer MCX ASP
Materials: Metal and Nylon Fiber build.
Weight: 7.75 Pounds (3.5 kg).
Barrel: 17.7 inch steel rifled.
Propulsion: 88 or 90 Gram CO2.
Action: Semi auto with internal blowback. Single stage trigger single action trigger.
Ammunition Type: .177 caliber pellets.
Ammunition Capacity: 30 rounds belt fed.
FPS: Claimed up to 495 fps with 4.2 foot pounds of energy (5.7 Joules).

Trigger Pull: The trigger pull on the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is actually pretty light and smooth when you consider the first part of the trigger pull is used to advance the belt fed 30 round magazine. You would think there would be more added friction from the belt but this does not seem to be the case. There is some internal blowback action going on but it is only used to cock the internal bolt/striker which does lesson the overall amount of trigger pull required. The trigger pull is fairly short considering all that is going on and it's not overly heavy so quick and predictable action shooting is more than possible with the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle.

Accuracy: So far I have not done my official Field Test Shooting Video for the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle. That said I have performed shooting test with my Sig Sauer MPX and Sig Sauer MCX Virtus. Both of these Sig Sauer similar styled Air rifles where able to get nee tight groupings close to .5 inch groupings form 30 feet and 50 feet respectively. It will be interesting to see what the actual fps is using a standard lead .177 caliber pellet as the rating on the box is in Joules and not fps. I will assume a little under 500 fps.

Build Quality: The build quality for Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is very good, you can tell Sig Sauer had a lot of hands on in the design and production of this Pellet Shooting Air Rifle! The materials used and fit and finish are top notch and the mechanical function again is really good. I am kind of amazed at how well Sigs belt fed magazine design works in terms of feeding and operation as all the Sig ASP Rifles use the same mechanical system and magazines. Sig also tests their APS Rifle line to withstand 15,000 rounds reliably.

Realism: The Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is a 1 to 1 replica of the real steel Sig Sauer MCX Rifle and looks absolutely the part other than the rear stock which has to accommodate the 90 gram CO2 tank. If you didn't know the rear stock was covering up the large 90 gram CO2 you probably wouldn’t have any idea and would probably think it was juts an aftermarket rear stock. Everything else about the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is pretty much bang on in terms of realism including a fully working ambidextrous selector, magazine release and drop out magazine, charging handle and pop up sights.

Pros:

  • Few pellet firing multi shot semi-auto replica rifles on the market.
  • Near perfect replica of the real steel Sig Sauer MCX including licensing and trademarks.
  • Awesome build quality, lots of metal parts and the nylon parts are true to form and very solid.
  • Gun has been tested to shoot over 15000 rounds reliably.
  • 30 round full size belt fed magazine has super high capacity and works flawlessly.
  • Canada Legal version with max 5.7 Joule, should get decent fps.
  • Trigger feels really good, not too long or to heavy and very consistent feel on every shot.
  • Fully adjustable pop up front and rear sights.
  • Lots of rail options for accessories, Picatinny and M-Lok.
  • Expecting it to be very accurate with it’s 17.7 inch rifled barrel form my experience with other Sig Sauer MCX and PMX Air Rifles.

Cons:

  • Rear stock is none adjustable so the gun may feel kind of cramped for larger shooters.
  • Internal blowback action does not advance the belt fed magazine but does cock the internal hammer.
  • 88 and 90 gram CO2 can be a bit pricy but yields lots of shots per CO2.

Comments:

I really like the line of Sig Sauer Asp Pellet Rifles and it’s nice to know have one to offer to our Canadian Online Replica Airgun Shoppers! Some people have given the SIG ASP Air Rifle Line a bad rap but I think fo rte most part this is due to poor pellet choice. My findings with all of the Sig Sauer ASP Air Rifles is that once you find a pellet that works with it, you will have consistent pellet feeding and excellent accuracy. There are now a lot of CO2 BB Modern design Air Rifles out there but not many that shoot pellets in semi auto with a rifled barrel and high capacity magazine . Sig Sauer has done a great job bringing this missing product to the Airgun industry.

lots of fun

Ran about 600 rds through this, so far just a few jams, nothing serious, good and powerful at 10 yards, sighted up wit a pinty scope,( not the best ) Totally satisfied with the power and accuracy, using Crossman Destroyer and a few different 7-10 gr pellets, found most to work pretty well, drills a hole in 1 and 1/2 inches of interlocking floor mat foam from 10 yards using Crossman pointed 7.9gr. Solid for about 150 shots, then starts to drop FPS. Look good, feels god, fun to to fire.

Jamais déçu avec Sig Sauer

Excellent rapport qualité prix, construction comparable aux model d'origine. Sig garantie a vie ce produit cela en dit long. Super le fun à tirer. Elle est lourde et solide bonne ergonomie elle est agréable a tenir. Elle est aussi bien précise pour un modèle de style combat " ce n'est pas une carabine pour le tir olympique" j'ai grouper a 1 pouces sur mes premières cibles a 20 mètres avec les mires d'origine. C'est la gachette qui fait cycler le mecanisme de distribution de plomb dans les magazine "roto belt" je suggérerais de bien graisser les chaînes dans les magazine pour faciliter le cycle cela améliorera "le triger pull". Personnellement a ce prix la je ne m'en passerais plus. Je l'aime.

low velocity

It is a fun gun when you get it sighted, but does it ever eat pellets to get there.Loading takes awhile but you get quicker the more you do it. I had to move my table from 45 feet to 30 feet for this gun to have any chance of hitting a target. Gonna upgrade to an Air Venturi HPA to see if that helps. If not, I've wasted a lot of money. Good thing I kept my Stogear

Screams quality

The moment you pick this rifle up and feel the weight of it, you will know you made the right choice. Extremely well made with solid craftsmanship you should expect coming from SIG SAUR. Every moving part of the gun came well oiled including the Iron Sights that come with this gun, which are fantastic. The Picatinny rail is high quality and the Suppressor on the end is metal which was a nice surprise when I picked it up for the first time. This gun is extremely accurate and comfortable to shoot so if you're looking for a training tool to keep your shooting skills up and run drills with, this is definitely an excellent choice. To date, I have put over a thousand pellets though this gun and haven't had a single issue. Jerry from customer service recommended that I use RWS Meisterkugeln Wadcutters and I haven't had a single jam thus far. There is not much else to add that hasn't already been said in the reviews above but so far it operates exactly as advertised. I will update this review if I encounter any of the issues some reviewers encountered. RAG.ca is an excellent site, this is my first purchase with them and I'm happy with the customer service leading up to my purchase. My next purchase will be the Dan Wesson 715 4" Stay tuned.

Sig > Crosman

In the past few weeks I have brought a few SMGs in to my home. Three to be exact. One is on my kitchen table with a nice scope, laser and a flashlight mounted as well as a bipod to go with the existing handle that came with it. It is set up at 30 feet and it is awesome. Looks awesome, shoots awesome, accuracy is ok but considering the two automatic capable Crosmans I have bought (one from here) have a BB stuck in the exact same spot on each after shooting a total of about 100 shots between them, I go with the Sig every time. Mind you competition isn’t stiff, I’m just not sure I will ever buy another Crosman product.

Love it!

I’ve put 500 rounds through this gun now and I’m very happy with it! Seems to be quite accurate with two different types of pellets I’ve tried. CO2 lasts for about 300 shots which is amazing! Just such a fun gun for target practice in the yard! Highly recommend it!

Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle Field Test Review

The Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle is my third go around with the Sig Sauer ASP Series of MCX and MPX Air Rifles. Back in 2016 I tested out the Sig Sauer MPX ASP .177 Caliber Pellet Rifle and it performed pretty well for me. Recently I reviewed the Sig Sauer MCX Virtus PCP .22 Caliber Pellet Rifle and again got good results once I figured out the right pellet for it. So here we are again with a very similar Sig Sauer Air Rifle....

The Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle performed well for me in general, I did find that occasionally the belt did not index resulting in a misfire (no pellet fired) but the next pull of the trigger would index the belt resulting in a pellet firing, there where no jams and all rounds from the belt where fired. I am not sure why this happened as this did not happen to me with my other Sig Sauer Air Rifles. Perhaps I short triggered it a bit not getting a full belt index. I know many of you have been waiting for a Canadian version of the Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifle, now that we have them in the All Black Iron Sight Version and FDE Red Dot Version, make sure to get one as once we run out I am pretty sure we will no longer be able to get these Canada Import Legal Sig Sauer MCX ASP .177 Caliber CO2 Pellet Rifles.
