I have been reading through the posts on the gas piston "grades" ill call them since im not sure if its an up or down grade. The thing im curios about is how it works. The one part that really gets me is how the bolt works in the carrier since with the direct gas it pushes the bolt forward. I dont know what force would do that if the bolt is being phyiscally pushed back by a rod and not gas. I understand the main principal of it i think. Gas goes through the normal hole in the barrel and pushes a piston back which just pushes the carrier back. It then returns via the spings. So if anyone can give me a more in depth idea of how this works im all ears. Thanks, Major |

I just got an LWRC gas piston upper. Here's a page that shows an animation of how it works towards the bottom of the page. www.lwrifles.com/tech.php Also, here's a short video that shows the system uncovered, explained and demonstrated. www.lwrifles.com/Video/LWRC_VIDEO.wmv I consider the gas piston design a refinement, not an indictment of an already pretty good design. Just figured I needed to get one while I still can. |
