As a little FYI, Peter has released M4 mags in 1/16 as an option https://www.shapeways.com/product/P66HK6G6F/1-16-spm-16-022-5-56-magpul-hk-mags-in-fastmag-p?optionId=73178927 As a service to you all, I’ve ordered some and will let you know just how good they are soon. Being a big fan of all things Samofptr, I expect the mags will be worth the money.
These arrived today, and are excellent. There are quiet a few mags on the sprue in different configurations. All are excellent. Thanks, Peter.
