Howdy all––long time listener, first time caller...I have a quick question that I wasn't able to find elsewhere on the sight. I apologize in advance if this has already been asked:
I am new at the AR15. Assembled my first lower, went wonderfully. I built it as a carbine, using the shorter carbine spring and buffer. When I went upper shopping, I found a great deal on a unit with a 20" Wilson SS Bbl, and bought it...but now I'm wondering if I may have screwed up. Is it safe to use a carbine buffer/spring combo with a long-barreled upper? Moreover, if it is safe, is it still not a good idea? I'm assuming that the only reason the buffer/spring unit is smaller on the carbine is to allow for carbine stock compressing/contraction, but is there more to it? For instance, does the weight of the buffer make a difference in comparison to location of gas port? Any help y'all could give me would be greatly appreciated. I first put this thing together with a cheap (though nicely built) collapsible stock, and the stock came with a receiver tube, buffer, and spring. I'm thinking of upgrading to a PRS, and after reading the fine print from Magpul, I'm not so sure if the receiver tube extension, buffer, and spring that I have would be the best choice. Do I need to upgrade? V/R Sixtigers |
