(heh, nothing like having to mod-move my own thread cause i posted in wrong forum)
just a quick post about using rear bags from a discussion on another site i'm sharing here as it may be useful for some
YMMV using different brands of bags and stocks, etc, but the following pics are using the str8laced bag with 50% fill, which i modified by sewing a sling swivel on it so i can attach it to the stock so that it follows me through the match and never gets left behind or falls out of my pack or whatever. It's always where i need it. As i said elsewhere, in this case, I would have preferred the flush cup on this stock to be on the bottom or at least low, but high still works. I didn't get to choose.
The carabiner is used on the occasion where i want to detach it from the rifle, i can hook it to my belt
(i really do think that camo pattern is screwing with my iphone's autofocus)
In the following pics you can see the bag is rectangular and has a strap on the 'length' side and one on the other side on the 'width' side, for lack of better term. It also has grommet rings on all 4 corners through which you can run paracord and do other things i never found particularly useful.
The advantage of a rectangular bag is that it offers you 3 different 'heights' in one bag. for example, prone, i lay the bag flat. if i need a little elevation, i'll turn the bag up on its side which turns it from a 2-3" thick bag to a 4-6" tall bag. If i need a lot of elevation, typically shooting off my knee or something, i'll orient it standing up so it becomes an 8-10" bag.
However, you can also use the 'rear bag' in front, when shooting off barricades or other obstacles. It can make a big difference in stability by putting it between the forearm and the barricade.
In these pics, you can see what the straps are used for. The long strap allows you to stick the entire barrel and forearm through it. so you can keep the bag more or less in position while moving between barricades.
In these two pics, especially the second side view, you can see the sentinel stock forearm is very very low profile compared to manners, AICS/AIAW or similar. The latter will have much less slack in the strap. Either way, the strap isn't adjustable so it will still slide forward and backward (especially when you don't have the NV rail providing some friction)
To solve that, if I have time, I again use the flush cup attachment to hold it in place.
You can also see looking down, that my sling is still attached on the right side while the bag is attached on the left. In the top pic, again, the sling is still attached on the right while the bag is attached on the left.
In these two pics, you can see the alternative, attaching the bag 90* to the above pic, to the bipod instead of going over the forearm.
there are lots of reasons that you might want to use one or the other of these options, such as whether you're also using a clip on NV, or if your support/barricade is fixed and closer or farther away, or if you need more or less height, etc.
Also, if a given stage will involve both prone and barricade precision shots, I often just use the flush cup without the strap because it's time consuming and sometimes difficult to maintain muzzle discipline while sliding the bag over the end of the barrel.
Although it will just hang off the left side of the gun when not using the strap, it's pretty simple to move it under the forearm with your hand while you're slamming into the barricade.
Anyways, I hope this is helpful
