S&W M&P-15 Compatible .22 Magazine for the dedicated .22 AR-15 Platforms

cults3d

Here are our 3d print files for the S&W M&P-15 .22 AR-15 rifles. At the moment we just have a 10 rounder available, but hope to have a 20 rounder at some stage in the future. If you purchase this 10 rounder now and see the 20 rounder is available, send me an email and you'll get a copy of that for free when it's available. I print these out in PLA+ and use an off the shelf round spring. The springs I use are 9mm OD with a 0.8mm wire diameter. I buy these as a 1m length and trim them down to about 110mm. You can see these magazines running here: https://youtu.be/7OIXiViNs74 Please be aware that your local laws may not allow you to make these, or may limit your capacity (here in NZ we're not allowed the 20 rounders any more). Don't be that guy that gets us all a bad rap!
