I'm trying to figure out what buffer tube assembly is on this AR Pistol. I will admit to making the mistake of buying somebody elses new and untested build at a gun show. I've been working out the problems with it and am almost there. Ever since I bought this, I was assuming the entire upper was a GSE(Gunsmoke Enterprises) package with the GSE buffer tube on a new Plum Crazy lower. It sure matches their package on their website. After having major problems with the buffer assembly binding up, I began emailing GSE for help. After shooting approx. 10 rounds, the spring end will stretch up and over/onto the carrier body and bind the entire thing up, total lockup. GSE swares they have never heard about this problem and in their last email to me said :
"There is a company that copied our design. The buffer tube is screwed into the lower with no castle nut or egg plate. It sounds like theirs. " So...........I think they may be right, no castle nut. Here are a couple pics. Does anyone have any idea who's buffer tube this is ? Right now we just took a standard AR spring, cut a couple inches off it and it seems to be working OK. I don't know that I want to keep the setup as is though. http://www.rpmmotorsportstulsa.com/Gregs/ARP1.jpg http://www.rpmmotorsportstulsa.com/Gregs/ARP4.jpg |

Quoted:
Maybe that entire tube is threaded and the middle smooth part is also threaded on the inside, so you tighten it against the plate, then install the rear cap... Yes. Has anyone ever seen a buffer tube assembly like this ? Still trying to figure out whos it is. |
| GSE ...GunSmoke Enterprises.......they have 2 versions ....one uses a carbine spring over the outside of a reduced OD bolt carrier.......the other uses a spring similiar to a 1911 (longer) recoil spring that is nested inside the bolt carrier........been meaning to build a 5.56 pistol with one.......but up to this point I can only comment that they work well on DI Pistol caliber builds....have built 5 or 6 .45 pistols with them.....just built a 5.5 inch barrel .45 that I'm gonna try one on as soon as I get a chance to make one up....... |

Please read the original post. GSE claims it's not theirs but a copy. If someone copied the tube, they copied GSE's carrier too. Mine is just like what's shown on GSE's website. The spring goes over a modified chrome carrier end. http://www.gunsmokeenterprises.net/2nd%20gen%20recoil%20kit.jpg Is GSE lying to me ? Is this really their setup ? |
