Here's a list of what I have considered so far:
-DPMS LR-308: Wait time of 1 year+, $1,900 with options. Unsure of accuracy.
-Armalite AR-10T: Shipping end of 2009, $1,892, 1 MOA.
-Patriot Ordnance Factory P-308: 25 week wait, $2,500, 1 MOA.
-Les Baer 6.5mm Grendel Super Varmint: 12 week wait, $2,500, .5 MOA.
-DSA Inc. SA-58 w/ 21" bull barrel: $1,850, unsure of accuracy or wait time.
-LWRC SABR - Shipping July 2009, $3,000, unsure of accuracy.
-Fulton Armory Titan: $2,800 w/ options, unsure of accuracy or wait time.
I already have a Colt .223 with a 16" POF upper, and a .308 PTR-91. I wanted to purchase the most accurate rifle at a reasonable price (some rifles cost $1,000 more without any gain in accuracy). I was also concerned about magazine and ammunition availability.
I was leaning towards the Les Baer 6.5mm Grendel because of the .5 MOA guarantee and only a 12 week wait. C-Products has 25 round Grendel magazines available (although Midway doesn't seem to have any 6.5 Grendel ammo in stock). The 6.5mm Grendel round would offer increased range and accuracy over a .223 with the same size rifle, and only 5 less rounds per magazine.
Are there any .308's with a .5 MOA guarantee, under $3,000, with a wait time less than 4 months, and with readily available magazines? I would buy a .308 over the 6.5 if I could find one with those characteristics.
