Great Product and excellent customer service.

Yes, I was very happy to finally receive my MPX last October (2021) I also received the MCX soon afterward. The packing was excellent, with nothing missing, Just load and shoot, basically. Replica Airguns was quick and professional with the shipment. I ordered 6 more mags for them, lasers, a bi-pod ( MCX), and a scope. 40pcs- 88g CO2 cyl, a hundred 12 g cyl, targets, and some other stuff. Spent the last few winter months inside, target shooting and getting familiar. Easy to use, ambidextrous, fast rate of fire. Just good old fun. Can't wait to get outside. Then, last week, MPX stopped firing, no gas was getting into the chamber. Called SIG, and sent it in for repair under warranty. (Very responsive service department by the way ) The next week, the MCX did the same thing. Both of them had something loose inside that I could hear. So, I sent that in as well. Now, I am hoping that I can have them repaired and back soon, since it's time to go OUTSIDE to shoot, and I have no air rifles. I will update this review as soon as I hear what is going on with these Airguns. I also have an M17, P226' and a pair of P320's, so I do believe in this company. UPDATE. GREAT, I have received two replacement rifles from MD Charlton, the company that takes care of the Sig products in Canada. These guys were great. Michael and the staff had inspected the rifles and decided to have them replaced. I was expecting to wait 8-10 weeks, but I had my replacements within a month. No hassles or delays, questions or excuses, just excellent service and updates on the return as requested. I have run a few rounds thru each, and all works well. I would add that this is an honest review, and I am not being compensated for this. I will say that I am very happy with my new airguns and more than pleased with the excellent service from MDC and Sig Sauer. Thanks, guys and gals.

Sig Sauer MPX ASP .177 Caliber Pellet Rifle Field Test Review

Sig Sauer MPX ASP .177 Caliber Pellet Rifle Field Test Review

730 - 11/2/2021 6:23:03 PM

In this Review Video I focus on the shooting performance of the Sig Sauer MPX ASP .177 Caliber Pellet Rifle to find out what kind of FPS we can get out of it and exactly how accurate the MPX is from 30 feet back using a fairly stable semi rested shooting position. I'll tell you right away my Chrony Chronograph has officially called it quits and I will be looking at replacing it for future Field Test Shooting videos. Lucky for us Sig sent me their real world inhouse testing using both 5.25 grain high velocity pellets and standard 8.18 grain lead pellets. Read full article here:

Sig Sauer MPX ASP .177 Caliber Pellet Rifle Table Top Review

227 - 11/3/2021 6:35:40 PM

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 steelrifled. 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) 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. Read full article here:
