I have one and put in a 12 ft/lb transfer port. also have shoulder stock. I had to return 2 shipments before they tested and sent a 3rd. I am very happy about all aspects of it's performance. maybe someday, i'll get a regulator.
the are uTube trick shots that show the incredible accuracy of the Lothar Walther barrel.
it's the lightest 12 ft/lb rifle I own.
Like Don said the 1720 is great. I bought mine used and it has been modified a bit.
A PRod TP and a bit heavier spring has it shooting just below 12fpe with a 7.33 grain JSB pellet to stay within the boudaries of Pistol Field Target.
It is wearing a Rocker1 LDC in addition to furniture from Alchemy Airwerks which includes the wood, a SS safety, trigger guard and all the screws.
A 3-12 Hawke Vantage scope with a custom sidewheel made my Mike at AirgunStocks.com.
Sometimes it wears a Crosman shoulder stock...
Bought my 1720T used, and it's an absolute laser that averages sub-1/2" five-shot groups at FT-maximum 35 yards, and sub-3/4" at 50 yards. Now set up for field target at about 12 foot-pounds. I built a Mannlicher fore-end for more muzzle ballast (for shooting from a bipod). Here are the details-
It's a rifle, it's a pistol. You can shoot ft pistol and rifle, and then swack ground squirrels at obscene distances. It fits into a med pack, and with a pickle on the end, no one knows you've shot.
Regulate it and you've got 30 good shots. Play with the trigger, put an aftermarket shoe on it, and you've got a 10 meter gun.
It really is an amazing little gun that everyone should own.
That is the Crosman 1399 stock that fits all of their pistols. The cheek-riser was made by Mike in Ohio. It is solid aluminumand effects the balance quite a bit. In the forearm I melted some .45 caliber lead bullets to offset the weight of the cheek-riser. The whwole package cn shoot right along with most PCP rifles. There is a fellow who who shoots WFTF s a member of the Crosman Team and he uses a 1720T in carbine configuration. I think there may be video on the Crosman site.
