Things I liked:Easy to follow instructions.
Things I would have changed:Allen wrench that comes with the kit is junk.
What others should know:Don't use the allen wrench that's included with the kit. It will round out the allen head screw.
Things I liked:Truly the only way to put a sling on most break-barrel guns, getting the barrel band adjusted perfectly is a bit fussy, but not actually difficult. Decent swivels and very fairly priced.
Things I would have changed:Maybe use a polymer sheet between the band and barrel for a more secure interface? Definitely include a better allen wrench with the kit (the one my kit came with was poorly sized and not very hard).
What others should know:Installs well on my HW95
