I had mine sent back because the stud on the bipod was not at bottom dead center. After paying over a grand for a rifle, I expect stuff to be perfect. Anyway, BM replaced the barrel on my new rifle [and] installed the new style handguard... because it was the barrel that was defective.
BTW, it took two months because the Varminter barrels were not in production at that time. The wait was more than worth it, IMHO.
