Underground Tactical Bolts
#1
Has anyone used these?

They sent us two of them to try out and from just a visual inspection they seem to be pretty high quality.

If I remember correctly their first run was out of spec. However, they quickly corrected the problem. I believe Satern has been using them as their primary supplier.

With the materials they advertise that they use, if they're specs are correct I wouldn't hesitate to use one.

I purchased a bolt from Satern late last year once they got them back in stock
If this was one of the those listed above, it works great and looks to be of a very high quality

I bought one last summer, put it in a 14.5 pinned Sabre Defense upper, been running great. When I first got this gun up and running I took this bolt and carrier, and flip flopped it with the group in my AA overwatch, shot about 20 rounds in each with no problems. I just had to put a heavy buffer in the short gun but the Underground bolt runs fine in both my Grendels. I used go/no go gauges, looks the same as the AA to me.

I got one right after they became available and have used it ever since with no drama. I also have a PF bolt as well. Both are well made and work in the 3 6.5Gs that I have.
