Dakota Tactical D54R reverse stretch MP5 clone. I've had this for a couple months and only put 3 mags through it. Comes with the Maxim collapsing brace, 4 mags, extra bolt head and case. Asking $4000 plus shipping or trade for a Staccato XC, Nightforce ATACR 1-8, thermal or NV clip on. Willing to entertain other trades also.
