| i remember seeing an artical in a gun mag about a company making a piston driven upper a year ago. from what i recalled, the photos on the upper looked pretty impressive. I am not refering to the ZM weapon systems either. the upper looked liked a typical M4 upper with a RAS mount. the bolt and carrier looked exactlly like an AR unit. the only differance was that this upper had a gas piston system similar to that of a G36. it was possitioned exactlly where the gas tube would be. If anyone has any info or photos please let me know. I would be really interested in one these if it exist. |
| There are two system right now, besides the HK system. Leitner-Wise has a system and a forum in the Industry section. Their website is: leitner-wise.com/. Also, Patriot Ordnance Factory (POF) has a system. They too have a forum in the industry section. Their website is pof-usa.com. I don't have experience with either one, but if you do a search on either, you should turn up lots of good info. from other forum members. |

I have the POF 9" OCC upper and it is a very nice piece. I have only shot about 300 rounds through it so far but I didn't have a single issue and when I took it apart it looked so clean that I decided NOT to clean it. I can't say that I ever did that with my other direct gas impingement AR's. I think I will be getting my 10.5" upper converted by LW and do a direct comparison. The one thing I like about the LW system is if anything happens to the gas piston system you can convert it back to direct gas impingement easily and quickly (according to phone discussion I had with someone at LW). Can't do that on the POF design. |
