Ejection patterns tell us ......

Shoot us a pic of your clone 416 and how is it running? Tell us about your build. I have buddy with a near perfect clone, but I have not shot that bad boy.

Pics are taking forever to upload for some reason but here’s the build…

HK upper rec
Nefarious Arms chf 10.4 barrel
BRN BCG, vented gas block and pistol assy
Geissele 416 SMR
SOCOM RC2 (going to transition to RC3)

Geissele SD lower
HK spring and buffer

For the 416, it seems like the spring and buffer are fixed in the equation because the spring is the heaviest you’ll find on the market. I’ve tried all the others. lol.

The gun runs great overall but suppressed it ejects about 2:30 depending on rate of fire. Faster and it moves farther Forward as I would expect. I haven’t tried it on the FA lower yet. lol. It has about 1k rounds thru it so far. The gun itself is pretty heavy but it shoots super flat for recoil impulse. Way flatter than my gas guns of similar configuration.

I’ll try to get pics if I can ever get them to upload.

I don't know the weight for the HK buffer. I wonder if a PWS steel-body buffer could be incorporated (or if the HK buffer already has a heavier body mass than aluminum)?

Honestly I could use an H3 but I popped a RC3 on it to test and immediately got 3:15-3:30 ejection plus it runs well unsuppressed. Now if they’ll just release the FDE RC3s.

I have a mid gas Noveske skinny Afghan 14.5 barrel that while accurate is very over gassed. When first assembled it's ejection pattern was so far forward that other shooters came to me to mention it. I'm guessing 12:30-1:00. I'm using the BCM version of the Vltor A5 system. I was using their lightest buffer. I went to a Geissele Super 42 rifle spring and a BCM #3 buffer. That tamed it to 1:30-2:00. Next I added a LMT E carrier and the #4 buffer. Now it sits at around 3:00 so I'm happy. I have a BRT reduced gas tube so that's my next step but I think it's good for now.

We took a stock Colt 6920 last weekend and subbed an H2 for the H buffer that it came with. Shot 5 rounds each without changing my kneeling position, and the ejection was identical. H2 seemed to have a little more pop, but that could have been only in my mind. Decided to leave the H buffer installed.
