LTAC Raven 556 Extended Magazine Release

New unused LTAC Raven 556 extended mag release. Bought not realizing you need the left one as well and assumed it would work with a standard mechanism. It won't. So, I put a "standard" AR-15 extended mag release on and this is surplus. 

Will trade for a Glock 17 or AR magazine or reloading supplies. 

Able to meet in Dartmouth, NS weekdays or will ship on your dime.  

Thanks for looking.
