Yes you can put a bipod on any rifle.
I put one on my Savage 93.
Harris.
An accessory
a rifle that is on a bipod,tripod,stand,wheels or on a vechile is a gun eg LSW is on a bipod so it is a gun.
If you mean the Remington 540X, while it is not intended to be fired from a bipod, one can be installed.
It all depends on the Rifle and bipod model.
Have you gone to the maker's website or tried an internet search on airsoft?
You normally attach a bipod to a rifle not a gun. But if it has a rail under the barrel then you can try that. Attaching a bipod all depends on the manufacture. Some will work with a rail, others have to be screwed into the stock.
Not yet, but the spartan will have a bipod and it may be full-auto or semi-auto.
Highly recommend you don't do it. If you just have to, go to a large gunstore.
There are many places where one could purchase a Simmons rifle scope. The best places to purchase Simmons rifle scopes would be gun stores like Optics Planet.
