I am finally getting around to asking this question.  Am curious about the VFG that came on my Troy A4.  I purchased the firearm in March 2020.  The VFG that came on it was a lightweight plastic/polymer VFG that came loose the first time I shot it.  I was unsuccessful in trying to tighten it back onto the rail.  After examining it more closely, I concluded it was an absolute piece of crap. I ended up ordering a "Modular Combat Grip" VFG made of hardened aircraft aluminum (https://worldoftroy.com/grip-modular-combat-blksgri-trg-a0bt-00.html) and discarded the original VFG.  The new one has been rock solid.

Am curious what type of VFG came on yours and your experience with it.  

I have a few stock Troy CQB VFGs and never had a problem with any of them. Last time I looked it seemed like there were putting something new/different on their others.

Thanks for the response.  Unfortunately I was so disgusted with my original that I threw it out once I installed the new one.  In hindsight I wish I had saved it for comparison sake. I can only assume that yours is a newer better designed VFG.  Mine was absolute junk.  

The one in the link above is on mine, well was, its a POS too.

Sheesh the ones I've seen down here have nice aluminum mlok VFG's that look like a pineapple grenade (Troy brand)
