    I made a couple of my 6oz A5H3s in to the A5Mod1 4.55oz (my scale) A5 Mod 1s to try in my KAC SR15E3, BCM 14.5" BFH midlength, BCM 16" midlength 3gun rifle, and my BCM 12.5" SBR.

    I have a BCM 14.5 middy L/W with BC w a H buffer . I put it on my Colt RR and dumped a mag with xm193 and can't believe how smooth it is shoot.

    My DD 14.5" LW upper was not reliable with the A5 kit including standard buffer. Weak ejection and a couple of bolt over bullet malfunctions using full (.223) power 77gr SMK reloads. I also had weak ejection with a 55 gr load that's reliable in everything else, (but no malfunctions in limited testing.)

    I swapped the complete A5 lower to the 16" N4 Light Basic and all is well. The other lower with CTR, carbine extension, and H buffer went to the 14.5" - which made it 100%. The 14.5" now fits in my M4 soft case as well.

    I shot my 16" BCM chrome-lined barrel 3gun rifle and my KAC SR15E3 with a VLTOR A5 Mod 1 buffer (4.55oz) this is just a A5 5oz buffer but with one of the tungsten weights replaced with a steel one. Both rifles felt a bit better and cycled smoother and flatter with the muzzle lift vs using the 5oz buffer. The KAC ran 100% with Black Hills 55gr, PMC Bronze 55gr, Black Hills 62gr TSX red box. It wouldn't run at all with Wolf. It wouldn't even eject the empty 50% of the time. The BCM ran 100% with the all the same Black Hills and PMC and would run and cycle the Wolf just fine but wouldn't lock back with empty. The whole while when shooting Wolf it felt like it wasn't even hitting the back of the buffer tube/receiver extension it felt like the bolt carrier was going rearward enough for ejection, cocking and feeding but buffer didn't feel like it was hitting the back of the buffer tube/receiver extension. The bolt velocity felt very different from round to round using Wolf.

    I also made two A5 Mod 1 (4.55oz) buffers from my BCM BFH 14.5" midlength SBR and for my 12.5" BCM SBR and will be testing those to guns next week sometime.

    While waiting for Vltor to release their "middy" buffer I rolled my own, actually two. As you know the regular A5 (H2) buffer has two tungsten heavy weights, two stainless. Following suggestions made by other posters, I made an H1 (one tungsten), and an H0 (no tungsten, four stainless), 4.5 & 3.6 oz respectively.
    Using a Daniel Defense 14.5in middy with a Battlecomp and the regular A5 H2 buffer, I was having very infrequent failures to hold the bolt back with PMC ammo, no problems with Fiocchi . However with ASYM training ammo, the rifle would not cycle at all, I guess because this ammo is loaded weak on purpose (while being the most accurate and softest shooting of the bunch!).
    With the H1 4.5oz buffer, the carbine cycled well with the ASYM ammo, but there was one failure to lock the bolt back in ten full magazines. Going to the H0 3.6oz buffer proved 100% reliable.
    Function with the Fiocchi ammo, the hottest tested, was perfect, with no failures to feed or bolt over base failures.
    The middy was easier to control with these light buffers than with the slightly heavier A5 H2. The combo of the ASYM ammo and the light H0 buffer was incredibly easy to control! That will be my choice with this ammo. For PMC and Fiocchi I will stay with the H1, but for XM193 the regular H2 would be a better choice.
    Have any of you tried similar combinations allready?

    If I had to put that much work into making the A5 function, I would ditch it.
    I'll second that motion. seeing as the 14.5 mid swings toward the "soft shooting" end of the spectrum away from reliability, I wouldn't understand the purpose of an A5 on this configuration.

    likewise, I also don't understand the modern compulsion for a "soft shooting" 5.56. it can't be the harsh recoil - if it is, there are smaller calibers you know...

    so it must be recoil control in rapid fire. to this end I would sooner add a muzzle brake or a compensator or some other device that tames muzzle movement rather than something that affects reliability...
    never push a wrench...
