Dasan Glock lower
This Glock lower was worked by Paul Kim who is more known for his works with SureFire lights. It uses simlar design as a STI 2011, where grips can be replaced easily. Dasan has been making Glock barrels and slides(through Lone Wolf Distributors) so they seem to be the chosen manufacturer.
