I've had a couple failure to feeds during rapid fire (you might remember my "what would cause this" thread) and I've ruled out the mags as the problem. What I'm thinking is a heavier buffer slowing down the action Llowing the mag spring a bit more time to do it's thing will solve the issue. I watched a YouTube video about the new A5 modstock and the different weight buffers you can get for it. The differance in the ammount of carrier "bounce" between a carbine buffer and the heavy buffers is amazing.
So my question. Which brand/weight to get? H2 H3 Spikes ST2? Can you go too heavy? Any and all help is welcome. Posted Via AR15.Com Mobile |

I use an H buffer in my M4 14.5" Bushmaster and a DPMS "Heavy" buffer in my 20" rifles with collapsing stocks.
Both these buffers have worked perfectly with 55-77 grain ammo. An H buffer is like 3.8 ounces I believe and the DPMS is something like 5.5 ounces which is near the same as a standard rifle length buffer. Most shooters can't shoot a semi-automatic rifle fast enough to make bolt bounce an issue. You just might try changing your choice of ammunition for the intended purpose you are using the rifle. I might add that Wolf ammo is crap, plain and simple and I find the gun school crowd extremely funny when they say, "Yeah, Wolf is OK to use." then relentless chastize the guy who shows up with the stuff and has one malf after another, telling him his rifle is a piece of shyte and he shoulda bought one of these, blah,blah, blah. |
Here is cool chart I found some time back.
Yes you can go too heavy .. what buffer are you running now. I would probably go H2 ... doubt you'll need anything heavier unless your running suppressed and even then H2 usually will compensate enough for the extra pressures. |

I'm using XM193 so the ammo being under powered shouldn't be the issue

It's the stock carbine buffer that came with the Delton kit. |
