Have any of you tried it?
I have a spare Knight’s lower (SR-15 Mod 2) that needs a new upper. I only have two hang ups over buying a MR556A1 upper:
1. No chrome lined barrel
2. No adjustable gas block
Despite this, I just got my tax stamp for an OSS 762 suppressor, so I figured a MR556 + OSS can might work well together.
TFB liked the new MR556A1 upper: TFB Review: Heckler & Koch MR556A1
I still want an adjustable gas block and chrome lined barrel though, lol
