Fixed Versus Collapsible

When you think of fixed stocks, most gun owners think of the A1 used during the Vietnam era. The military chose the A1 buttstock to provide the general population of soldiers with a weapon that could fit anyone who fired the rifle.

Unfortunately, the fixed A1 stock required the rifle owner to be facing their intended target and didn’t allow too many opportunities to fire in a prone or kneeling position. Another issue with a fixed stock is just that. It’s fixed and can’t satisfy various degrees of a length of pull requirement.

Being able to adjust the length of pull is especially important if multiple shooters use the same rifle. It’s even more so when participating in a competitive match where accuracy and speed are paramount.

If, however, you’re the only one to use the rifle, and you don’t care for cold-weather shooting, you may want to consider purchasing a fixed or possibly an adjustable sniper’s stock that quickly becomes a worry-free part of your AR15.
