I am putting together an AR15 upper and have noticed several of the slimmer handguards use Keymod or Magpul mounting systems by which to attach rails. As I do a variety of testing involving various scopes and external battery units, having some versatility would be an advantage.
Can somebody explain to me what the advantages would be to either system, distadvantages, etc? Is one easier to use? Is not not as secure?
