Type: Pellet Rifle.
Manufacturer: Sig Sauer ASP
Model: Sig Sauer MPX ASP
Materials: Metal and Nylon Fiber build.
Weight: 7 Pounds (3300 Grams).
Barrel: 8 inch steel rifled.
Propulsion: 88 or 90 Gram CO2.
Action: Semi Auto, double action only.
Ammunition Type: .177 caliber pellets.
Ammunition Capacity: 30 rounds belt fed.
FPS: Up to 600 fps (When shot by a Unicorn)
Trigger Pull: The trigger pull on the Sig Sauer MPX ASP .177 Caliber Pellet Rifle is actually pretty decent when you consider the first part of the trigger pull is used to advance the belt fed 30 round magazine. One would think that there would be a lot of 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 hammer/striker which does lesson the overall amount of trigger pull required. The trigger pull is shorter than expected with all that is going on and it's not overly heavy so quick and predictable action shooting is very possible with the Sig Sauer MPX ASP .177 Caliber Pellet Rifle.
Accuracy: So far I have not done my official Field Test Shooting Video for the MPX ASP .177 Caliber Pellet Rifle but I did have the chance to get out and shoot some rounds down range at my Sig provided Quad Shooting Gallery that I had setup about 35-40 feet away. Even though I did not have my red dot all perfectly sighted in I was still able to hit the smallish metal targets fairly well using the Sig Sauer MPX ASP. In terms of velocity you can expect from the Sig Sauer MPX ASP .177 Caliber Pellet Rifle, 600 fps is a bit optimistic. Sig did send me a real world fps performance spread sheet they had conducted using both 5.25 grain alloy pellets and 8.18 grain lead pellets shooting 8 rounds and averaging out the fps. The 5.25 grain pellets averaged in at just over 500 fps while the heavier 8.18 grain pellets came in with an average of just under 450 fps. Pretty much what I would expect from a shorter barreled CO2 rifle.
Build Quality: The build quality for Sig Sauer MPX ASP .177 Caliber Pellet Rifle is excellent, 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 their belt fed rotary magazine design works in terms of feeding and operation. So far I have not experienced any pellet feeding problems at all using both lead and alloy flathead pellets.
Realism: The Sig Sauer MPX ASP .177 Caliber Pellet Rifle is for the most part designed to be used as a side by side optional training aid for the real steel Sig Sauer MPX Rifle. Sig wanted the pellet version to look and feel as close as posable and Sig has done a good job with this. Other than the lessor recoil and noise factor, the Sig Sauer MPX ASP .177 Caliber Pellet Rifle works and shoots much the same as a real steel Sig Sauer MPX Rifle.
- Has to be the best semi auto pellet rifle replica I have seen and shot to date.
- Near perfect replica of the real steel Sig Sauer MPX including licensing and trademarks.
- Awesome build quality, lots of metal parts and the nylon parts are true to form and very solid.
- Rifle has been tested to shoot over 15,000 rounds reliably.
- 30 round full size belt fed magazine has super high capacity and works flawlessly.
- Decent fps performance, about what I would expect from a multi-shot CO2pellet shooter and totally usable.
- 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 rails for your pick of sight options and other add on accessories.
- Very accurate with it’s 8 inch rifled barrel.
- 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.
- FPS claim of 600 fps seems a bit optimistic compared to real world testing.
I have been waiting to get my hands on the Sig Sauer MPX ASP .177 Caliber Pellet Rifle for some time now and the wait has been worth it for sure. There are really no other guns out there right now other than perhaps the Umarex CX4 Storm that compare to the Sig Sauer MPX ASP .177 Caliber Pellet Rifle and even so I feel the Sig Sauer MPX is by far the better of the two CO2 Air Rifles. OK so the MPX does not really come close to hitting 600 fps but did you really believe that in the first place? Still consistent 450 fps from a decent grain lead pellet is about what you would expect from a short barreled CO2 rifle. If you do want more fps then look at the MCX with over double the barrel length of the MPX, this will easily get you an additional 100+fps for those of you who thrive on velocity performance. I am fine with 450-500 fps since this is all that is needed to accuracy shoot and nock over most targets at a variety of ranges.
My YouTube Table Top Review of the Sig Sauer MPX ASP .177 Caliber Pellet Rifle:
To celebrate our Canada Victoria Day Long weekend there will be free shipping all long weekend till end of day Monday in our Canada Replica Airguns Store on all Products! Make sure to take advantage of this limited time offer!
I was excited when I first heard that Sig Sauer was coming out with their own line of pellet shooting airguns and that was about 2 years ago! So it's been a long time coming for me to finally get my hands on one of Sigs own in-house Airguns. Sig Sauer was kind enough to send me three of their ASP (Advanced Sport Pellet) airguns, one of which arrived last week, the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. I will also be receiving Sigs P250 and P226 CO2 Blowback Pellet Pistols for review when they are sent to me hopefully soon.
I will be performing my standard Table Top and Field Test Shooting videos for all of the Sig Sauer Airguns being sent to me but wanted to get out this preview video for the Sig Sauer MPX ASP .177 Caliber Pellet Rifle to give you a little info on it right away and also let you know what's coming up in terms of Sig Sauer product reviews.
In this preview video I do a little bit of fun backyard shooting simply because I could not resist having a go with this awesome air rifle any longer and needed to shoot it. I was not disappointed! Every pellet I placed in the 30 round belt fed magazine fired flawlessly from the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. I used both Sigs high velocity 5.25 grain alloy pellets and some flathead 7 grain RWS lead pellets and all my ammo shot well in the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. I have not done a Chronograph test so far for the Sig MPX but can say the pellets where getting to my Sig Sauer Quad Shooting Gallery Target in no time and I had placed a good 35-40 feet away. Once I figured out my sights I was able to continently hit what looked like pretty small targets from where I was standing, this was no surprise since the Sig Sauer MPX ASP .177 Caliber Pellet Riflehas an 8 inch rifled barrel.
Sig has done some real world pellet fps testing on their own using both light weight 5.25 grain pellets and heavier 8.18 grain pellets and the numbers for an 8 shot average came in at around 505 fps using 5.25 grain pellets and around 450 fps using 8.18 grain pellets. That's plenty enough power to rip into your targets setup even further down range.
My Sig Sauer MPX ASP .177 Caliber Pellet Rifle is the open sight only version but you can get one already paired with Sigs Red Dot system or add your own sighting system, since there are plenty of rails to add just about any kind of accessory to the Sig Sauer MPX ASP .177 Caliber Pellet Rifle.
Check back shortly for my office Table Top and Field Test Shooting videos for the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. And when I do finally get the Sis Sauer p250 adn P226 ASP Air Pistols I will have review videos out for them too.
Seems like all I am focussing on is Airsoft guns lately, well that's just what is coming across my table at the moment... Don't worry I am sure there will be some BB gun reviews coming up shortly :) Anyway in this Field Test Shooting Review I take a look at the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol and test its accuracy and velocity. If you want some more details on this gun I have already made some other videos for the 4.5mm steel BB version so you can watch both my Table Top and Field Test Shooting videos for the 4.5mm Steel BB ASG Bersa BP9CC CO2 Blowback Pistol.
Getting to the actual Field Test Shooting review, I performed my standard five round Chronograph velocity fps test using .20 gram plastic Airsoft BB's with a brand new 12 gram CO2. The fastest Airsoft BB achieved by the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol was 413 fps and the slowest came in at 342 fps with a five shot average of 390 fps. The slowest shot was the last one in my Chronograph test and it even sounded a bit different like it wasn't getting full CO2 from the valve. This would present a problem later on in my accuracy test as it seemed the CO2 valve need to working in before this gun started to perform properly. I am guessing there may have been some debris in the valve area that needed to work its way out?
On with my Field Test Shooting portion of this review to determine the accuracy of the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol. I set myself up 30 feet back shooting from a semi-rested position (Sand bag up front and standing in the back). This shooting position serves to provide a stable shooting platform for overall accuracy and what I should expect to get from the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol. Keep in mind the results are always dependant on how I shoot on the day of my testing.
I shot rounds through the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol but as I mentioned before I believe the CO2 valve was messing with the guns performance, so what was happening was some shots would get full Co2 and work fine while other shots only got a portion of the CO2 which did not allow for the blowback action to fully cycle and caused the internal hammer to not get set in the full cocked position. I did get about half of my shots to hit the target but my results where not what I would expect from the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol. It is more than capable of getting at least a 4 inch group from 30 feet out so don't take this particular test to seriously.
After tearing down my camera gear I decided to load up another CO2 into the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol and shot several magazines through it. This did seem to fix the problem and which leads me to believe that I simply needed to work this gun in a little bit. Out of the box Airguns can have some machining materials in them that can cause performance issues as I believe was the case for the ASG Bersa BP9CC CO2 Blowback Airsoft Pistol. Luckily I was able to get mine working properly!
