Hi All I don't get many chances to get on and ask questions. I have been building a Bushmaster AR15 for awhile now and mostly have it operational at this point, However I am down to two components that I would like to upgrade. The Stock and the Handguards, I like the ARFX stocks but I cannot decide which I like more the full size or the Compact one?? For the HAndguards I would like to have a tactical rail system, I have spent much time peruseing the internets sources for AR parts and I am still no clearer on my decision than I was before. I have looked at both a Free Float 4 rail Handguard as well as the 2 piece 4-rail handguards, by various makers. I am hopeful that someone will have some input into these areas, as to what works and what does not. I do not especially want to buy a several hundred dollar item only to find out that it is not worth the aluminum it was made from. Thanks to anyone that has some insight in this area.
