5 of 5 Firefly is working better April 17, 2026
Reviewer: Mark from Deer Park, WA United States  
This spring seems to have help, it would not cycle at all before. Have only shot 20 rounds so far, but only had a couple of fte's. And no ftf's

5 of 5 Works wonderfully. As expected. November 6, 2025
Reviewer: Andrew Anderson from Evans, GA United States  
The recoil spring works wonderfully.  I expected it to work well and it solved by cycling issues related to the action.

5 of 5 First time buyer experience April 24, 2025
Reviewer: Michael Epperson from Locust Grove, OK United States  
Purchased only 1 small and inexpensive item. But I’ll admit to being impressed at the ease of navigating their website, the clarity of information, and ease of payment. That was followed by prompt, reasonably priced shipping with regular email tracking updates.
In sum, a great experience!
