I bought the Tippmann X7 forward grip with spring-loaded bipod for my HP 995 TS. The "feet" on the bottom folds into the handle and is released by a push button. Pretty cool. Unfortunately it did not the HP 995 forward bottom rail because it actually has 3 scope stops (!). In addition to the locking center, there are 2 more raised scope stops. So to use this on the 995 TS without either replacing the accessory rail or filing/grinding down 1 or 2 of the scope stops, I installed a short scope riser as an "adapter". It was sturdy enough to get me good 5 shot groups at the local indoor range. But I would not recommend this product unless if you replaced the accessory rail to standard MIL SPC rail.
