Need some advise on possible upgrades
 

Hey, so Im looking at some final touches to add on to my TM M14. Done the internals, and gave her a paint job, but I would like to add a bipod and a rail system to it if possible. I have found two on ehobby that seem ok. I just want to know if anyone has experience with either of these brands/products, and if they are just a piece of junk or a decent purchase for the price.
