i have one. it has a milled receiver long 20 inch barrel. has chinese writing on the right rear of receiver...(very accurate rifle). receiver marked
Mak-91...then underneath..NM-47 National Match.
basically it is a Legend with a long barrel.
it has a different receiver cut. different from the average milled Mak-90...trust me on this.
i bought a skeleton stock from ACE (www.riflestocks.com
)...got a recevier block for milled mak-90. it wouldnt fit. i had to saw/file some material off. the mak-91 has a straight angle cut ont the rear of the receiver similiar to milled bulgie slr-95.
oh yeh, the hammer is a diffent metal. it is gold in color. hope this helps.
ps. my heavy barrel is straight all the way thru. it is not "recessed" behind front site post to accomodate a bipod. it is defintiely not meant to be a RPK squad weapon.
