There also is 3 different versions of VSR-10 cylinder sets.
Make sure you bought the right parts for the right version. The stock one should be a regular. By the issues you are describing, you might have bought a bore-up kit.
The bipod mount on the TSD M700 is molded in the stock plastic. It is bound to break. You can buy a separate nub and replace it VERY easilly by drilling a hole for the screw and place it at the same place the stock one it. You can also simply install a 20mm rail at the same place, using the front barrel bolt and make a hole for the second one. G36C rails work good for that.
hey Kos, the piston came with the Zero Trigger (90 degree vs 45 degree piston).
And thanks for the tips. definately plan to fix the bipod mount. Bipod ftw!
