Question: How long are they?
Document: The punches arrived very fast and were perfect for the job that i had for them. They will be very useful for a long time.
Was very nice having these for my AR build. Don't know how long they will last, but I didn't bend any like most of the reviews on these punches.
The metal they are made from is way to soft, and the punch neck is way to long which makes them prone to bending.
This is a must have for any AR build and some of the more complicated gun smithing. They are a good quality and I hope they will last a long time.
Great tools and I really liked the storage bag. Solid construction and seems that they are going to last for a long time.
A great set of roll pin punches for a reasonable price..Don't know why I waited so long to buy a set
Can't believe I went so long without this punch set. Makes working on my AR painless. A must have for any gun owner!
I have been needing gunsmithing tools for some time and have purchased this set to help me when I work on any weapon. If care is taken this set should last for a long time.
Ordered this set to mount a Magpul enhanced trigger guard on my AR and they worked perfectly to get the roll pin out! All of the punches seem sturdy enough to last me for a long time based on my needs for them.
Needed if you do your own gunsmithing as roll pins are everywhere. I even have used the smallest 1/16&#34; one several times already. I'm waiting to see how long it lasts before starting to bend tho.
Answer: yes
