55’s not fully cycling in 223 Wylde 18”

[Ex E6]

All very good points, thanks for the feedback. I was thinking the same (its odd that the lack of a carbon ring would cause low pressure issues bc if so brand new guns wouldn’t cycle unless using very spicy loads). Ill be at the range again later this week and I now have a garmin chrono and some black hills mk 262 factory loads to test the cycling on. That should give me a good baseline and if it still doesn’t cycle I will definitely be contacting geissele. Im done fucking around with buffer weights. Everything ran fine for hundreds/thousands of factory and hand loaded 5.56 rounds (50-77gr) with an h2 buffer plus super 42 spring.

Here's another reliable port sizing spec sheet . IF You ever order a barrel or upper ,You can specify what port size you'd like .

When I order a barrel I always have a smaller port size ,that way I can drill it myself so as to make exactly what I want .

Largest port size I've ever had to drill for an AR15 22.5" Rifle is 0.094" it was sticky at 0.092". On 98% of all MY 20" barrels run 0.088- 0.092" . My 16" barrels are mid length and run 0.076" ,0.078" and 0.82" and I've got a slew as well as variety of manufacturers of those .
