Jon K 32 Posted January 3, 2023 you running a rifle length buffer on this? Thought the upper is using a mid length gas system. Any issues? Share this post Link to post Share on other sites

No issues at all. the combination of the heavier rifle buffer and the mod bca does to the extractor results in smooth reliable cycling. remember, wolf and tula have faster powder burn curves so at minimum its recommended h2 for x39. This is my third build with exact set up over past 6yrs and probably 15k total (my first and second builds I abused with cheap wolf ) and zero issues with tula, wolf, tiger, bear or NF in any. I'm just leaving the caliber, no more AKs etc, Share this post Link to post Share on other sites
Jon K 32 Posted January 3, 2023 Appreciate the info, have this same upper being delivered tomorrow, and was wondering if i could use one of my rifle length lowers with it. Share this post Link to post Share on other sites
RUTGERS95 889 Posted January 3, 2023 It won't at all, I prefer it. I'd change the hanguards though Share this post Link to post Share on other sites
