Gentlemen, I am looking to build my first AR. I am wanting to build it as a long range piece. 20-24 inch barrel (24 looks like those are hard to find, so probably 20). I am just getting started with the lower, and working on the wife for more budget money... So far I have a Quentin Defense U.S. Army billet lower. (I fell in love with that rollmark.) And a Daniel Defense parts kit. I know at some point I'll need a trigger upgrade. I am looking at buttstocks and just can't seem to decide between the Tactical Intent TI-7, Ergo F93, and the Magpul ACS (all mil-spec). Any help deciding between those would be appreciated for the type of shooting I am building for. If I am way off base on those, please feel free to tell me so, but please propose an alternative. And yes, I know, I should a want a Magpul PRS... the budget officer will not allow that level of expenditure. I need to be in the $150 range for the buttstock, spring, buffer, nut, etc. Thank you.
