How can you attach a sling to a Browning 2000 shotgun?

Answer 1

One has two options, in both cases, a rear swivel stud can be used, but not absolutely needed:

1. The age-old tie method - tie fore end sling to bbl and either tie or attach to swivel at butt-ed.

2. The B-2000 forearm cap is a machined gas port. To add a sling swivel cap, one needs a cap with swivel/port accommodation. Not easy to find, but there are a few makers out there.
