mmm that just enough stuff makes me nervous. "Just enough" + a little dirt or a little light on lube might become "not quite enough".
One of my initial requirements of a gun is it reliably go bang with any commonly available ammo, even in adverse conditions. Call me paranoid.
I put together a BCM 16" middy, with the A5 system. Love it. Just over 800 rounds without a single malfunction. I have been a little surprised that the recoil impulse is a little harsher than some of the other rifles I have owned, and others I have shot. Using my search button, I see I am not alone. I bought the 2 heavier A5 buffers to see if I could notice a difference.
A5 H3 (6 oz) buffer, no noticable difference, casings all landing approx. 4 'oclock, 6 to 7 feet away. Same location as standard A5 buffer.
A5 H4 (7 oz) buffer, did notice reduction in recoil "harshness". Rifle "felt" smoother. All casings landed in the same location as the standard and H3 buffers.
I was prepared for some possible short stroking with the H4. None at all, though I only shot 2 magazines with it (60 rds). I know that it is not scientific, but it did feel better, and no short strokes yet, so I left it in for now.
I was shooting Federal Green Tip.
I did shoot a full magazine (in 3-4 round bursts) through a suppressed M4 at the OFASTS shoot a few weeks ago. I was impressed with how "smooth" and controllable it was, but I think the suppresser tamed any muzzle jump.

Has anyone had any issues with their 14.5" mid lengths in extremely cold weather?
Proven combat techniques may not be flashy and may require a bit more physical effort on the part of the shooter. Further, they may not win competition matches, but they will help ensure your survival in a shooting or gunfight on the street. ~ Paul Howe
This is add copy from Asym's website regarding their 5.56 55 FMJ-BT training round:
Don't have time to look anything on Hornady's website, but I suspect it's loaded at the upper end of SAAMI-spec. My point about pressures and 14.5" middies is don't be surprised if you have short stroking/failure to lock back issues if running weak SAAMI-spec ammo. Asym ain't weak, and I doubt Hornady would be characterized as weak.Based on our experience, and leveraging the experience of world class instructors, this is what we believe is needed in a carbine training load, and what our Precision Training load delivers:
1. Complete reliability, so the shooter can focus on absorbing and perfecting new training concepts. We accomplish this through
•Intelligent Load Specification: Precision Training is loaded at what we consider a “sweet spot” of pressure and velocity for high volume training purposes. It is loaded warmer than common commercial .223 spec and a bit softer than full 5.56 NATO. This accomplishes the following:
◦Enough power to run milspec ported and spec’d fighting carbines. Many commercial .223 and foreign loads are underpowered, causing malfunctions. We test our load for proper function with rifle, midlength, and carbine gas systems with milspec porting, auto and semi bolt carriers, carbine/H/H2/H3 buffers, in barrel lengths from 10.5 to 24".
◦Eliminates popped primers when used in 5.56 chambers. Popped primers due to over pressure ammunition/incorrect chamber specs have been a consistent problem of late
◦Prevents excessive wear and tear on the weapon.
•Quality Components, including fully processed once fired military brass from DoD sources, milspec hardness USA made primers, Hornady 55 gr. FMJ-BT bullet, and clean burning propellant
•Unrelenting quality control. Every round is chamber checked and hand inspected. Every case is checked for a flash hole. Every primer is checked, every powder charge checked. We test fire on a very frequent basis.
And I do agree with you, more problems arise from trying out the next greatest gadget and tweaking 5 parts of the system, and then you run into problems and you don't know where to start. Keep it simple and feed it good ammo and you'll be GTG.
