I built a Tikka CTR in a Bravo Chassis. I added weight to the frame in 2 places, the forend and the butt plate shims. I have a very good machinist friend that help me out this this. If anyone would like the Drawings I would be happy to share.
I had 3 goals with this weight system.
1. I wanted to be able to add and remove the weigh to fit the mission. If I go shoot P-dogs with is I will add the weight, If I have to pack the rifle I can make it light. Since the Bravo is designed to be light, why not keep the option?
2. To be able to Balance the rifle in front of the mag well. Once I shoot this barrel out and re-barrel it, I still want to rebalance it.
3. To add support to the extended arca rail. I ordered the long rail with the Bravo but found it has to much flex when the bi-pod is mounted on the cantilever section when preloading.
The system has 3 weights I can add. The first is a weight mount bar. This bar slides into the forend frame under the handgaurd and is attached to the chassis by the 4 mounting screws for the spigot. The second is a front weight that gets attached to the mounting bar. The third are steel shims in the butt plate. My intention is to always leave the mounting bar under the handrail in place and balance the rifle with the but plate shims.
Weights:
11.9lbs - Rifle stand alone ( Tikka CTR Factory rifle 6.5 Creed. Vortex AMG, Bravo Chassis with extended arca rail, Patriot Valley arms Jet Blast Muzzle break. no mag or ammo, No Ckye Bi-pod)
19lbs - rifle, bi-pod and
full weight set. (ckye bi-pod - 1.46lbs)
I was able to add 5.64lbs of weights , plus 1.46lb bi-pod = 7.1lbs total added.
Balance point
1 - light setup, no bipod. The rifle balances with the weight bar added and no rear shims.
2. Light setup with Bipod. The rifle needed two rear shims added. Wt = 16lbs. This is an Ideal weight for me.
3. Full weight added, no Bipod. The rifle needed 3 rear shim plates.
4. Full weight with Bipod(far out). With 3 rear shims the rifle balanced about 2 inches in front of the mag well.
I won't say this is prettiest thing in the world but it sure did work. I will get it Blued (black) this supper.
