So I started having an issue with my Manticore bullnose forend the other day and was wondering if anyone was in a similar boat. It appears that the slot the charging handle rides in does not line up exactly with the bolt, causing it to bind when charging. Specifically, it is sitting higher than the hole in the receiver for the bolt. I only noticed this when because when cleaning the forend had a little wobble, so I tightened up the barrel clamping block and the screws that mount the forend on the block. When I reassembled, the charging handle was hard to pull and slow to return to battery. I even took it off, examined it all, reattached, etc. When "loose", its fine, but when actually solidly attached, it binds.
Is this a known issue with the barrel clamp or just user error on my part?
