F5 MFG

I have never given a rating this low, this company is worse than Walmart or Amazon. I took almost 30 days to receive my order even though the website said in stock every time I checked. There is no phone number to call and they don't answer emails. There is a paint chip on the can tube and the golf ball tube has minimal threads on it and it isn't centered in the can tube. The only positive thing is I received 2 extra blanks. I haven't used it yet as it's -20 here and I'm almost afraid to use it.

No response from customer service after repeated emails. My gunsmith said the chamber needs to be cleaned up a lot. Dont you test fire these things??? Blank will not chamber, bolt carrier will not seat blank in chamber. Measured the blanks and shot one out of my rock river ar and it works fine, NOT the blank If i could give zero stars i would. Waited for a month from initial attempt at contact to post this review, you had plenty of time to respond.

bought the acr to scar conversion stock and it had so much play in the lockup that it rattled and depending on how you held pressure it would change your sight picture. messaged customer service with pictures showing the problem and gave them a week to respond(which they didnt). Took it back off my scar 16 and tossed in a bin of spare parts, what a waste of $250

This stock did not work with my Century Arms AP5. I have tried to contact F5 Manufacturing through regular emails, phone calls, internal chats and emails with no response.

Had to put one star… deserved ZERO!
