VPRS SPRING FINDER
Find the right spring
for your setup.
1
Your rifle setup
Four details. Start with what is installed.
AR-15 options are grouped by rifle, pistol, and rimfire cartridges. Peak chamber pressure alone does not determine spring choice; gas-system details matter. Use Other / custom if yours is not listed.
Choose a preset; offerings vary by make and caliber. Use Other / custom to enter an exact unlisted length.
Verify compatibility and installed parts on your exact rifle before purchase.
