Good Morning Gentlemen,
I'm a daily lurker and infrequent poster.
I use a Manfroto 055 for photography work with both gimble and ball head mounts.
It supports my Nikon pretty well, even when it's wearing a 6.5lb. Sigma 150-600 lens and teleconverter
It's a nice tripod though I've never mounted a rifle on it.
90% of my shooting is BPCR Silhouette or BPTR and tripods aren't in the rule book.
This may ruffle some feathers, it's not my intention to do so.
Amazon sold / sells a tripod similar to this one without the pistol grip mount.

A number of years ago I bought one for use with my spotting scope.
It's HEAVY and strong. Many of the reviews alluded to Russian tanks.
It's much "stiffer" than my Manfroto and supports more weight.
It's never blown over, be it at Ridgway or here on the N Atlantic during a 'noreaster.
If the OP is interested, I'll search my past amazon orders and get an exact part number.
I feel it's a lot of tripod for very short money.
Hope this helps.
Craig
