Is my 102 perfect, no. Did I send it out for warranty work twice, yes. Would I buy one again, HELL YEA!! It's an amazing tinker rifle.
Mine currently sports a 6.5cr match barrel, triggertech trigger, and a whack of other AR10 parts. Swapping barrels is a breeze (takes standard off the shelf DPMS barrels). Mine and my friends (he also converted his to 6.5cr) shoots sub MOA at 100 all day long.
Rifle is backed by a lifetime warranty backed by SFRC (Ryan stands by this product).
I can't wait to get another upper and have one in 243 soon.
