Rifle Scopes Need help with iron sights

[B-boy]

Hello everyone I'm in the process of purchasing a Beowulf for hog hunting. I want both a red dot sight and BUIS. I'm undecided as to which Iron sight system would be best, the fixed front sight gas block or the folding sight on the railed gas block ? I have a carrying handle with adjustable sight to install on the weapon while hunting close quarters with the iron sights and an Eotech with qd mount for a little further out. which front sight would be best for this application ? Walk and stalk hunting with the iron sights, so quick acquisition will be of most importance.

Thanks everyone
