A rifle bipod can be purchased several different places. Most gun stores will have them in stock, as well as stores like Kmart in the sporting goods department.
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.
