i have been shooting armi sports spencer rifle 56-50 fore a wile now ,good and bad points ,mine fuctuns very well but go over screws with locktight especily firing pin screws triger pull is heavy easy fix , balance of rifle is much beter than carbine,now the down side when i got mine the fore stock was very loos the barell bands look lick they ment for another type of rifle(dont buy sight unseen), if was to desine a barell that wouldnt shoot i would copy this one,the chamber is way to long and the twist is miles to fast to work with lighter 320gr to 375gr bullets,if you want it to shoot you have to youse450gr bulletsthen it realy shoot well i am sure barell was desined for 50-70 ,this is fine if you yous it as a single shot but with 450gr bullet oal to work through magizine you can only get 30gr of pouder in case, also the sights are badly made and will need modifing or replacing i recomend replacment,before i bought one i would get in touch with armi sports and ask wen they are going to put the right barell on it
