Hey folks,

Give me your thoughts.

After installing the BF stock, I noticed that the front ferrule no longer touches the stock and given that the BF has an Op. Rod Guide that provides a forward attachment point, and can provide a downward draw on the barrel, I wondered if unitizing the gas cylinder provides any value (in terms of improved precision) in this set-up.
 
nope.
Get a shim to take up the left over space.
Honestly Frank should have thought about this and sent them with the stock when he sold them.
 
There is no way to dampen barrel whip on the BF stock past the oprod guide... Where incidentally, most of the barrel whip is occuring.
Unitizing your gas band will improve barrel harmonics by eliminating any band vibration

So unitizing with the BF stock will still serve a purpose? How much of an improvement does this make?

Unitizing serves a purpose, has nothing do with the BF stock.
Unitizing won't do anything to prevent the natural barrel whip, only vibration.
Again nothing to do with what stock it's in. Chassis stocks with fancy oprod guides aren't supposed to have a gas band plate. Instead, a precision made washer is used. And no, this does not get unitized

Good Morning All. Replacing the front band is not necessary to correctly install the Blackfeather "RS" rifle stock and it does not affect Blackfeather function or accuracy.

If I added a replacement spacer to our stock kit to replace the front band, it would add dimensional changes that might require a M14 shim kit as well.

I got some flak when I decided to add a oprod spring guide to each Blackfeather rifle stock but I decided that this part was related more to the core function of the rifle and in a small way, would affect overall accuracy of the rifle stock: therefore, it became part of the system.

I guess I could have viewed the spacer/shim kit the same way, but I don't have the resources to spend time making replacement washers and shim kits: third party vendors like Marstar do that already and not every customer will need them. Everyone "needs" a four fluted, oprod spring guide, don't they? :D They're being blackened today and will be shipped to our first Blackfeather customers by late next week.
 
Follow Up Question

So 45ACP,

While I recognize that unitizing has nothing to do with the BF in particular, when the BF is installed, the front ferrule no longer contacts the stock and the BF Op. Rod Guide can be used to put downward "tension" on the barrel and gas piston assembly.

In other forums, I've read that one purpose of unitizing was to allow the front ferrule to contact the stock and damp vibration. Further, that the unitized gas cylinder cylinder/ferrule could be tweaked to put downward pressure on the barrel and gas piston to improve precision.

So if unitizing would still provide a benefit to rifle precision by damping the barrel vibration, how much effect might it have?
