will a Hammerli 850 AirMagnum with scope fit in this case
Will this fit my Airforce Airguns Texan 45 with a high mount scope? Do I need to remove the bipod to make it fit?
Yes it will fit. If your bipod folds, it should fit fine
will this case fit a hastan bullboss and a sumatra 2500/500cc ?( both unscoped) I need this for air travel
I would not recommend this case for air travel. You'll want something like this: Plano Double Scoped Rifle Case...
Will gamo bone collector hunter (new model ) with leapers 30mm 3-12x44 fit this case
Yes, it will
What is this foam made of? is it Open or Closed Cell?
It is open cell
Will this case hold and protect my M4-177?
Yes, This case will protect your M4-177. HOWEVER This is a bit too big for just one M4-177. If you have other guns however you can fit them together with the M4-177.
