I’ve had my 7615P for about 5 years and I do dearly appreciate it.
When I bought it, the stock it was wearing was one of collapsible pistol grip type that’s adjustable for length of pull not unlike the Knoxx Breacher stock (pistol grip stock is for sale btw).
10 rounds at 200 yards off a rest.
I’ve have since changed the stock out for the traditional OEM variant and had the barrel threaded for my Gemtech Titanium Trek suppressor.
As you can see, with the can attached to the rifle the balance point is right in front of the magazine (perfect spot for one handed carry in the field).
I shoot it quite often and I find it to be a very accurate and fast handling Carbine.
