Ever Wanted to Shoot a Grease Gun?

Developed in the early ’40s as a replacement to the Thompson M1 SMG, the M3 (and later M3A1) is commonly referred to as the “Grease Gun” because it looks incredibly similar to the mechanic’s tool. The Grease Gun was primarily chambered in .45 ACP, and uses 30- or 32-round magazines. The M3A1 variant was introduced in 1944 – with several design improvements over the original – and saw a little combat at the end of WWII, but saw much more extensive use in the US-Korean War. This weapon is a simple, no-frills SMG: cheap to make, easy to produce, but still a lot of fun to shoot.

Customer Reviews

  • The Only Firearms Dealer I Trust

    “I wanted to thank Machine Gun Tours and especially Kyle, who helped me in every way and helped me make an informed decision in purchasing my first Colorado handgun, the FN-5.2. We took it to the mountains and let me tell you. It’s the firearm of the future. Thank you Kyle, you really took the time for us to do it right. Now you and your company are the only firearms dealer, I trust or for that matter anyone else should either. And less expensive I might say. Don’t waste ur time, like I did with other dealers, go here first. Kyle, Because of you. I’m going to come back for an AR next.”

  • This Is My Go-To Gun Shop

    "I am new to Colorado and made my first gun purchase through Machine Gun Tours. When I first walked into the store I thought it was a little “beat up” looking, but realized that they have a lot of product and just need to stock it and make it a bit more presentable. The staff was lights-out knowledgeable, and very friendly. While I was waiting for my background check to come through, I was watching them interact with other customers. In my opinion they were looking out for the customer’s best interest as opposed to overselling them on junk they didn’t need. They had intimate knowledge of the firearms they sold and made solid recommendations to me and others that either walked in or called in. They also offer concealed handgun permit training and other services that gun companies can’t offer. These guys are top notch, despite the not so spit and polish showroom. I plan to buy again soon and won’t consider buying anywhere else at this time. This is my go to gun shop."

  • I Will Buy Again From These Guys, Hands Down

    "I was looking online for parts for my AR and was having a hard time were I live in western Colorado. Finding Machine Gun Tours online I gave them a call was pleasantly surprised to find a store the was very informative and stocked quality parts. So much that I even made the trip over to Denver to even have them work on my gun. Thank you. The best thing I thought was a true benefit was that they have employees that have real world knowledge of the AR platform and knew what they believe is quality and what’s not. They have extremely fair prices on parts and services and can beat anyone I have encountered with knowledge. I will buy again from these guys hands down…"

  • You Will Not Be Disappointed

    "If you are not 100% satisfied with were you are going for your arms and accessories you have to give these place a try, you will not be disappointed. I dealt mostly with John and Alan and I can’t say enough about them and MGT. First off, these guys don’t have a hint of arrogance that we all know so well that usually comes with other local shops/ranges. They both were nothing but professional, easy going, and respectful, once again NO ATTITUDE or ARROGANCE. They spent a good amount of time with me on different choices and even after the purchase made sure I was squared away for the paperwork that would follow. I’ve been buying firearms for over 25 years and have never run into a group or shop that has such down to earth respectful guys behind the counter, hell you’ll want to hang out with these guys at a BBQ. Anyway, I usually don’t take the time for these things but wanted others in the area to know these guys are the REAL deal, they run their business like it should be and like what we all once used to except. Definitely give these guys a shot, you’ll most likely be like me…..a customer for life. Also, an incredible stock and reasonable pricing. A+ all the way. The other gun shops and ranges should take lessons from the pros."

  • The ULTIMATE Shop

    "WOW, the ULTIMATE shop with firearms you can’t find anywhere else. Plus if you’ve ever wanted to shoot a machine gun, this is the place to do so! I’ve used them to pick up my first home defense guns, take my CCW class so I can get my Colorado concealed carry permit and had a great time shooting fully automatic guns at their private shooting range."
