This whole thing about the reciprocating handle is ridiculous , to say the least .
I have fired thousands of rds thru my Aks and Saigas , Psl , VZ58 , etc ,etc and never have had a single problem (or hitting my fingers with it) with the handle of any of those weapons . And to complicate things , I am lefty so it is more complicated for me than for a regular right hand guy and I never experienced any problem at all . Frankly , anybody who has his hand caught up on the handle while the weapon is firing , is a moron in my opinion .
I do find the handle on the Scar 17s too close to an optic and I can hit my fingers with the optic mount so , as a matter of fact, I just ordered the IWC charging handle which is curved and will save the skin of my fingers . The fact that the handle will move up and down when firing , is of no consequence to me ... after all , I have been using weapons with moving handles all my life .
