NYMetsFan86 9 Posted November 2, 2013 Id like to start a 9mm AR build soon. Always looking for different configurations to set my builds apart from others. I saw this polymer lower/stock combo that may be what im looking for. Any opinions on this lower in particular? http://www.marksarmory.com/GWACS_CAV_15_MKII_Polymer_Lower_Receiver_p/gwacsfde.htm Quote Share this post Link to post Share on other sites
Heavyopp 167 Posted November 2, 2013 Doesn't the lower on a 9mm build need the mag well machined for the proper mags??? Did you plan on using some sort of insert instead? Quote Share this post Link to post Share on other sites

NYMetsFan86 9 Posted November 2, 2013 yes i planned on using the adapter insert. similar to this... http://www.jsesurplus.com/promag-15-1-1-1-1-1-1-1-1-1-1-1.aspx there is also one for glock mags but i believe its a bit more expensive. This build will be to replace a void in m y safe where there should be an HK94 that is out of my price point. ...checking out the site now.. edit: always wanted zombie green haha. Wider magazine well accepts unmodified, submachine gun magazines in pistol calibers. With caliber conversion upper receivers and magazine blocks, standard AR15 magazines can be used without modifications. Quote Share this post Link to post Share on other sites
