The former Everton and Arsenal forward hasn't really done much since his £2million move to Charlton last summer but he will be hoping that this move will help him rekindal his best form. Jeffers had not featured in any of Charlton's squad's this season and he will face tough opposition for a place in the Rangers team, like Dado Prso and Nacho Novo.
In my opinion I don't think Jeffers is good enough for the Premiership and maybe the Scotish league might be the league for him. I believe it is a good move for Charlton because now they don't have to pay some of his wages. Jeffers will do well at Rangers and maybe a permanent deal would be good after the loan.
