For B&T side folders, the UMP style (with its longer LOP) feels better to me... but I'm 6' 1".
I’m running the A2 on my form 1 9CT and it’s a perfect fit.
The B&T stock looks too much like the SB Tactical folder that comes on the pistols. Yes, I understand that the stock came first and SB copied the look, but every time I see that stock on a MP5, I think brace and pistol. For me, it’s the classic A2 stock. I also have a A3 F stock, but rarely use it.
Do you even HK, Bro?
