Seems like Hera Arms folding adapter has ball bearing inside, I got MDT one, it is loose. Adding velcro, hope that works
Btw, I have MDT LSS version, not Xl one, was debating and got it, but that adapter add length, so be careful with scope.
However, weight is ffne for me
I use an MDT LSS with a Hera Arms folding stock adapter. For a light build the LSS chassis is hard to beat. I'm running an AAC-SD 16.5" barrel, ctr stock +riser. With the scope and bipod attatched its 12.54 lbs
The folder is great, no slop when locked open but when in the folded position it only has spring tension to keep it folded.
Do you have a pic of your setup you could share. I have a 16.5 and i'm looking at option on what to stick it in.
