You’re right by all accounts that the items you mention are also contributory to felt recoil - I agree !
My point is this: when you run a rifle stock as the factory put out, each rifle is it’s own animal, with a non adjustable gas block you are stuck at that amount of gas being sent down the tube to the BCG.
Given no changes elsewhere you can expect that same amount of gas on each trigger squeeze.
What if - the amount of gas at the factory setting is more than what is needed to effectively cycle the gun??? I’m driving at the factory setting being overgassed ...
How would it NOT lessen felt recoil to tune that gas amount to the minimal amount needed to push the BCG at the optimal level ?
No doubt you’ve not changed the recoil impulse of the gun/cartridge but you sure have changed how much is transferred down the tube to the BCG hence the shooters shoulder.
In final, it isn’t the end all be all method but it can contribute to lesser felt recoil
Recoil and felt-recoil are related but two different concepts. As long as you use the same ammunition recoil does not change regardless of how you adjust your gas. Recoil is the rearward force which is the application of Newton's third law of physics. As the bullet goes forward there is an equal an opposite reaction and there's nothing tweaking your adjustable gas system can do about it. 'Felt recoil' however is how much of that recoil is felt by you and this is what shooters are concerned about. Felt recoil is influenced by how much recoil is absorbed by the weight of the gun and the rearward movement of the BCG. Also influenced by if you can smooth out the impulse so a short sharp shock of recoil feels more forgiving if it occurs over a longer time.
I agree, that if you impart more rearward force into a BCG when it eventually comes to a stop that force will oppose more recoil than if it moved just enough to cycle properly. But, it will bash around your action more than necessary. Relative to other calibres the Grendel is not savage recoil, even in a light weight AR. Why then would you prefer your action to get bashed by more gas than necessary for a small reduction in recoil you are unlikely to even notice?
