I posted this over in the AR Pistol forum, but this seems a better place.
Gents, I have two new AR pistols that I am currently working on. Spikes Lower Centurion 10" MK18 upper Daniel Defense BCG Spikes T3 Buffer Std AR buffer tube 17-7 Spring Here is the question. Seeing as this is my first build, I went (in error I think) with the T3 Buffer 5.4oz. The one pistol is running ok on green tip, but I have had a couple doublefeeds and I am not happy with any mfs. The other when running range ammo went for about 6 rds and then would not extract and eject everytime nor pick up a new round, sometimes one prob, sometimes both. So question is did I go too heavy, I seem to think so. If so what should I have gone with. I have always had standard buffers, but this time I had to make a choice. Here are the choices. Thanks in advance for the help. T3 - (Currently installed) 5.4oz T2 - 4.1oz T1 - 3.0 oz |

First rig, sound like you just need a H-2, while on the second, maybe a H-1.
Now having said that, and that difference in the buffers is the tungsten discs verses standard steel discs (3 disc in a carbine buffer), with just one standard carbine buffer, you could use on standard steel disc out it to swap to turn the 3 into a 2 and on the second, swap two tungsten disco with two steel disc, and turn it into a H-1. Plus the fact that you will have a standard disc before the insert swaps, could try it out in the second rifle as well. And the best part, with the Three tungsten discs you will have left over, will now have a H-1 and H-2 and can turn the new standard buffer into a H-3 as well. Note, have not ripped a T-3 apart to verity discs OD's, so check with spikes to make sure that the internal discs are the same OD as a standard buffer to allow the disc swaps. |

Quoted:
I am with you on the swap out; however, the 1 and 2 are powder and not discs. Only the three utilizes weights. I may just have to buy a 1 and 2 and see what works and sell the others. Thanks. If powder, every though about just getting a filler disc to take up some of the void, and removing some of the powder to lighten the buffer. Hell, for testing, you can remove all the powder and run the buffer dry. Although the dead blow effect at the back of stroke will give the mag more time to recover/get the top round up tight against the free lips, the dead blow effect to prevent bolt bounce has no really meaning in the semi auto world. |
