LilTMoney Posted December 30, 2016 Share Posted December 30, 2016 I just aquired a spike tactical 300 blackout. As i have it now it has a 7.5" barrel and a Sig SB15 Tactical brace. I dont want to deal with the SBR stuff so i ordered a 16" barrel. I like the SB15 and wanted to leave it installed and use it as a stock. I am trying to figure out what would be the best buffer to use with this and how the short stock will work with the longer barrel. Any and all input would be great!

I love it a lot. https://www.cheaperthandirt.com/product/maxim-defense-ar-15-gen2-jp-silent-capture-spring-standard-buffer-and-spring-for-maxim-defense-cqb-stock-685239761184.do?sortby=ourPicks&refType=&from=Search Link to comment Share on other sites More sharing options...
Mark Gale Posted February 15, 2017 Share Posted February 15, 2017 It would be cheaper and easier to tune the operating system by swapping out weights in your buffer assembly and/or changing the action spring. Link to comment Share on other sites More sharing options...
