The best cheap option is to shave the a-frame, as the pinned gas block will be very secure.

Next up is sending it to a good shop to have a pinned low profile block installed.

Short of that, use a set-screw type gas block with the barrel under the set screws being dimpled so the gas block won't walk forward over time.
