Why is it necessary to use lightened spring when shooting dedicated 22 upper? Will the light spring still work if you change back to .223?

The light springs were made for the .223 in 3.5 & 4.5 lb pull They are for
semi auto only .The heavier springs [std] were designed for full auto.
For the .22 upper use a pistol hammer ,the un-notched one. It comes in all DPMS LPKs"America will never be destroyed from the outside.

Thanks for the reply. One of my lowers have the un-notched hammer so I was wondering if I really need the light spring. Maybve I should try it out first before getting one.Comment

The .22lr conversions and uppers are more sensitive to variances and tolerances, and can have cycling/feeding issues with standard LPK's.
The lightweight springs coupled with a non-notched hammers offer the best reliability.Please read the Calguns Wiki
