Great springs
by Casey D -
All of sprinco springs are excellent. The 5 coil spring works great with the black insert and NO oring. It’s too much extractor pressure in my guns. They will help extract steel case and with running suppressed. I use these in every gun I assemble.
Good to go

What can I say it's sprinco. Get yours while you can.
Hiccups gone
by Danbo -
Cured my issues. Rifle kept jamming every other round. Extractor spring was .owing with my fingertip so it was pretty obvious I needed this part. Bam! Switched it out in about 10 minutes with no special tools and first trip back to the range my rifle fired flawlessly. Round after round. Fyi..After watching countless videos on YouTube I decided not to use the o-ring that comes with this kit. More people say don't use it than people saying do. Your choice. I didnt...no issues whatsoever.
Impossible to install
by Lee -
Poor quality. The spring seems out of spec and impossible to insert into extractor. Get BCM instead.
Low cost upgrade for peace of mind!

I've run this product through three of my AR's, including a 10.5" Suppressed SBR, 16" Suppressed Carbine, and 18" DMR...when combined with Sprinco's buffer springs, I've never had a cycling issue in any of my guns.
