Troy - Generation 1 - better design at ferrule - tighter locking.
Troy - Generation 2 - barrel band guide no longer tight in upper rail - stupid design move by Troy ?
JAE-100 G2 - Follows the original M14 design philosophy more than other aftermarket stocks.
The advantage over standard stocks - a standard bedding job by locking the receiver lugs to metal lug slides in the stock via allen screws pulling down the receiver into the stock.
The barrel tensioner seems to allow for adjustable ferrule lip pressure to achieve optimum barrel whip harmonics.
However - the receiver sitting on the top of the stock is not bedded - especially at the heel - very contrary to national match specs. (May not now be necessary?)
Since the trigger assembly no longer locks the receiver into the stock - it is loose in the stock - shimming was necessary for consistent lock time and harmonics. An obvious design flaw.
Sage and AKM Sage clone - The most standard bedding job according to match specs for the receiver, with the addition of free float from the op rod guide forward due to the op rod guide being bolted to the stock. The bolting has a positive effect on barrel whip.
The Sage also has a barrel tensioning screw at the front top for barrel whip. AKM can have one added.
Viron - Absolutely the best bearing system for barrel whip control. Allows the barrel to stretch when hot but not whip.
Great mechanical receiver heel clamp, but I found receiver bedding was still necessary.
Also - a lot of the coating material had to be dremeled and sanded for proper fit.
Accuracy shooting tests -
# 1 - Viron - same POI no matter how hot the barrel.
# 2 - Sage/AKM - always MOA with cheap ammo. Prints up to 2 inches lower with hot barrel - groups still MOA.
# 3 - G.I. fiberglass {or walnut} - epoxy bedded. Same low print when hot - slightly larger groups.
#4 - Troy - front end looseness showed on target - larger groups.
The SAGE/AKM's and epoxy bedded G.I.'s have shot 1/2 inch groups for me -
I have not been able to do that with the others.
As you can see - the JAE isnt rated - I have just finished accurizing a Springfield match rifle and mounted it in a JAE for someone. Going to test it on the weekend and rate the results.
What Chopper wants - a Sage stock with a metal Viron screw in from bottom receiver heel clamp, a JAE screw in from bottom receiver lug slides, a Sage 3 screw stock mounted op rod guide, and a Viron barrel bearing tensioning system. I wish. - If I had a machine shop ? Yeah !
Anyone else have test experiences ? Thoughts?
