For now I just bought a 1" UTG med .083 riser for my red dot so when I find sights they should co-witness Now , I'm trying to find decent flip up sights . It seems the Mbus are out of stock everywhere . So other than them what do you guys use ?? Are the chinaman sights worth it ? I really would like something made in the US . I was looking at Dagger Defense flip ups but theyre out of stock right now too . Vet owned company made in the US . Sounds good , they should be in stock soon . Anyone else have any ideas ? The rifle is a Spike's Skeletal Viking 10.5" pistol . It has a rail that runs from charging handle to flash suppressor so theres a bit of real estate for a pistol . What say you ? Would 45 degree offsets be worth a look ?
