First you have to let us know What Model Crosman Airgun or Rifle you are talking about. The model number is printed on the side of the barrel. Give us this information and re-post the question.
See the Crosman link below.

See the link below for the Owners Manual. Read the section "Adjusting the Trigger."
there should be a small square button found just ahead of the trigger guard on the bottom of the rifle.push that in while withdrawing the rifle bolt back.
Best to ask a gunsmith for assistance.
First, make sure the rifle is unloaded. Then pull the bolt back to the end of it's travel. Inside the trigger guard, just fwd of the trigger is a relatively small button (bolt release) push it and remove your bolt. Reverse this for installation. Hope this helps.
It looks like a slab of wood with a barrel mounted on it and a very thin trigger guard. The best way to Identify one is the fact it's a push barrel. It was made between 1961-1969. See the link below for the owners manual from Crosman.
No. Trigger guards for these were made of plastic.
Cannot find an exact match- but if your trigger guard is black plastic- and especially if it has finger grooves in the tail of the guard- it was probably made by Mossberg. You can order replacement trigger guards from havlinsales.com There are 3 different trigger guards- check the photos to see if they match your rifle.
turn the rifle up side down there is a small butten in front of the trigger on the inside of the trigger guard so open the bolt half way then push that butten then pull back on the bolt and it should come right out.
yes a BDL rifle will fit a ADL stock but the trigger guard will not but a new trigger guard can be bought for 20 to 50 dollars and brownells.com
I have a CNC Billet Aluminum tube fed trigger guard for a Winchester model 77. I have then polished or hard black anoidzed.
