Lilja's site states "the barrel extensions are a DPMS type and these barrels will headspace properly with DPMS type bolts", so -- assuming that barrel choice -- the field has narrowed. Although the nagging question now is his distinction between the drop-in and non-drop-in barrels. 0.012" difference in the OD... What is the tightest (least tolerance) that any of you builders have fitted a barrel? If you had an interference fit, how did you install it? What is the specification for DPMS style receivers barrel ID? More questions than answers. Kirk

I am planning my first AR build around the .308/7.62 cartridge. Right now I am gathering information and opinions for a better understanding of this not-quite-standard-AR realm. As such, I would welcome any pointers to existing discussions or related reference material to sort through my options. I am compiling a spreadsheet of vendor and product information to help me sort through the materials and compatibility of various resources. While this is akin to a buy vs. build decision, I hope to build because I am a tinkerer. On the other hand, I want to build a rifle that delivers accuracy like Les Baer promises. This is my first gas gun; I've been spoiled by 1/2-MOA bolt accuracy for decades. After much consideration, I've elected this path over an M1A -- in part due to available options, and in part due to the accuracy assured by the best manufacturers, coupled with the belief that if they can do it, then I can do it too. Time will tell... I plan to build a long range version, so it will have a 24" barrel to maximize the .308 ballistics. I think that I have the start & the finish figured out. It will start with a Geissele trigger and will likely finish with a heavy Lilja AR1024 barrel. Now I need to work out the details in between... I welcome your feedback. Thank you, Kirk
