These riser blocks work great. I work at a boy\'s summer camp where I run their rifle range and shooting program.
My predecessor in this position replaced the stock sights with peeps without measuring the front sight height. Consequently, I inherited 6 rifles that shot too high with not enough rear sight adjustment.
These riser blocks work great. They bring the front sight to the proper height and now the rifles are spot on.
I\'ve ordered 4 of these blocks and will be ordering 2 more to fix the remaining rifles.
