I have a build using an entry style short tube, basically the "doublestar" skeleton stock type "entry" buffer tube (7" or 7.5")
The issue I'm running into is the spring/buffer take up too much room in the tube and I'm left with only a 1/4 gap (perhaps less) behind the BHO lever. After test firing, I noticed the BHO was not engaging in time and instead hanging up right behind the bolt face and catching on the bolt carrier itself. I assume this is due to there not being enough of a gap for dwell time and the BHO lever cannot engage soon enough before the bolt attempts to return to slam home upon the last round fired.
The issue is not the BHO spring or magazines. This issue was replicated using 5 separate mags of various kinds. All parts function as they should. The issue I'm seeing is, there isn't quite enough room in the buffer tube for the bolt to travel fully reward, it's as if the buffer is too long. And after swapping the shorter 2.5", .308 buffer for a test fit, I noticed I had far more clearance behind the BHO lever as the buffer was not hitting the back of the buffer tube.
Secondly, I have paired this set up with the Stern Defense RAB-AD quick detach stock adapter. And with that, there is a little 1" spacer that is required for use with the adapter.
I've since ordered a flat wire buffer spring, however I suspect the buffer itself is a tad long, regardless of the buffer spring compression.
My question is, could a heavier, shorter AR10 buffer be used (the 2.5" .308 carbine buffer, replicating an H3 in weight)
OR
Are there 2.5" shorter AR15 buffers on the market that for some reason I cannot find?
Also, has anyone tried using a shorter .308 carbine buffer in their standard 5.56 AR? What kind of reliability issues did you have if you did, if any?
I know this is a long winded and scattered list of things/question but any help would be appreciated.
