I have a question about two Colt LE6920 models: the LE6920HBPW and the LE6920SOCOM.
As far as I can tell, they are all but identical except for the rollmark and the handguards. They both use a pinned/welded 14.5" SOCOM barrel. However, it seems that the HBPW comes with an H buffer while the SOCOM comes with the H2. The SOCOM coming with the H2 makes sense, that's what the military uses for their M4A1s. But why does the HBPW come with an H buffer? It is my understanding that the military/Colt puts H2 buffers in their M4A1's to prevent bolt bounce issues caused by the heavier barrel, so shouldn't the HBPW have an H2 as well?
If anyone has an LE6920HBPW, can you confirm whether it comes with an H buffer or H2?
Also, can an H2 buffer cause issues cycling low pressure .223?
