I’ll be honesty with you, I would have a hard time given you very many references on places you should go to, to get the answers and avoid a bunch of bullshit when it comes to firearms and accessories.   Gun forums have been around for almost 2 decades now, and even though some are better than others, there is always going to be a lot of BS and drama around certain products.   One of the best analogies I have ever heard when it comes to firearms is that they are just like Golf clubs.  Each firearm is good for its inteded purpose, but you don’t use a putter to drive a golf ball 400yds.  I have family friends that were draft bait in WWII and Korea, and most of them though the M1 Garand was a reliable platform and most said not everyone could shoot them very well, because they were all issued the same gun with the same stocks.    It’s amazing how much modification and stock accessories are out there now, even something like an M14 or M1A rifle can be converted to an adjustable stock.    Everyones length of pull is different and if the gun is too short or too long, it’s going to be hard to get into a good firing position and be proficient.

Mapgul stocks and accessories  are very well made and I have yet to had any of my AR15 rifles break on me.  I’m not one to bash synthetic stocks, and there is nothing wrong with the fixed stock on an AR15, but they don’t work for everyone.  Not only do people have to worry about finding rifle stocks that fit them, they have to think about what if I’m wearing a winter coat?   What if I am wearing body armor and  a tactical vest?   Being able to adjust the stock on your Carbine or rifle by 1-2 inches can be a huge deal as far as comfort.  The Magpul PRS stock will give you a great cheek weld and adjustability.  My personal favorite is the Magpul CTR stock.
