Default Op rod spring length?

I bought a new oprod spring from one of the vendors
At camp perry to replace in my field grade. The new
Spring measures 21.25 inches long and I double checked
The length. Is this spring too long to use?

According to my Kuhnhausen shop manual, the maximum specified free spring length is 20.25". I measured a new spring I just purchased from Ammogarand and it is 20" long. Sorry, I didn't answer your question, but others may be able to weigh in on usability of your spring.

I use a dremel cut off wheel/disc to shorten any spring that is over 20 1/2" down to that length or slightly shorter and then you never have to worry about the spring causing malfunctions. Just make sure you cut the larger diameter end of the spring and yeah, I screwed up one myself by cutting the other end some time back when I wasn't paying as close of attention and was cutting a number of them down before Orion 7 starting making their excellent SS springs.

that spring will more than likely cause function problems from being to long

Trim it before you buy another. This one's paid for.

What these guys said!

Quite a while ago I bought some "Original USGI" M1 op rod springs that were the same length as yours from an on line seller. The problem was that I did not know that before I ordered them.

They would not work and I end up sending them back. Either try to cut it back or just order a new one from Orion or another reputable seller.

If you should try trimming it down yourself...."Just make sure you cut the larger diameter end of the spring"
