I don't know you age or condition of your eyesight but as you grow older, eyesight gets worse. Rifles with rear aperture sights like the 1917, 1903A3 & Garandicon will let you shoot better, longer. Unless you are on a very restricted budget, don't let price deter you. If going on price alone, get a Mosin Nagant. Rifles regularly go for less than $100 & ammo is cheap as well (all the surplus ammo has corrosive primers so immediate cleaning is a must). If not on a restricted budget, start setting aside some cash & save up for what you want. The 1917 has excellent sights but they are not adjustable for windage. The 1903A3 & Garand adjust for both W&E. If you shop around, it's not impossible to find a A3 or a a Garand for $500. The CMPicon has excellent bargains & the cheapest surplus .30-06 ammo around (excellent quality & non-corrosive). The CMP has Garands now and sometime after the first of the year they will again sell 1917s and 1903s. CMP Sales

Study up on what you want. Be ready to act when you find it - opportunity is fleeting.
