My right hand has developed some arthritis so loading the box magazine on my 280 has become a bit problematic so I opted for a detachable magazine conversion. I looked around and the Magpul hunter kit was one of few that could hold longer cartridges as my 280 has a custom chamber, a bit of a bonus is that it will also take AICS magazines which provide even more length for the cartridge. It was definitely not a drop in as the magazine assembly is wider, longer and deeper than the hinged floorplate but I got it in after some careful fitting. It feeds very well being a single stack and for a polymer kit seems robust enough for my needs.
