absolutely not...it makes the upper/lower easier to manipulate and get in those hard to reach areas...while youre at it wanna clean mine??? i got 4 that i REALLY dont feel like cleaning
Was looking at the Midway catalog and saw all the vises showing the AR's open but not seperated and then I started thinking "OK, they're either trying to sell me useless shite or I'm doing this wrong" glad it was the former not the latter
And no thanks Bloodhound. I hate cleaning my own enough.
