I have this Tac 1, which is my test vehicle when I want to test some thing out. I changed the barrel out from the .177 to the Crosman .22 vantage barrel. It shoots really straight, is a smooth cocker, but the twang is outrageous. I just finished my rebuild of my spring compressor with a better design. I was going to address the noisy spring issue with it but priced a complete Crosman gas ram conversion for $56 delivered from Crosman. Fixing the twang would be easy, and almost zero dollars but being a test vehicle I am thinking of doing the conversion and seeing how it goes. If I don't do that I might cut a couple coils off and make a little gentler shooting gun out of it. I guess if you're not buying a new gun you're buying stuff for the ones you have. LOL
I used a heat gun to heat it up a little bit and it slid right off.
Wll, that muzzle brake is just light plastic, no weight at all. I use it on a different rifle just as a crown protector. That gun shoots well if you replace that barrel with a .22 of any b19 variety. It shouldn't be hard to cock, mine wasn't compared to some of my other ones. Good luck with it, they are fun little platforms to tinkert with.
B19 just refers to the type of break barrel it is.Go to the Chinese Airgun Portal, they have a list of guns that are of the B-19 platform. Any Crosman Vantage Optimus etc stock will fit. I find it is just as cheap to go through Crosman for the stocks as the shipping is only $4. I bought an Optimus stock with the hand guard and used my own screws for about $36 shipped. My Tac had a .177 barrel on it and I switched it over to a .22 Vantage barrel. I'm just going to order a new spring and rear guide for it from a Vantage, as the guide is extremely loose, and spring, in case I screw up on the cut down of the spring that is in it. All the parts are inexpensive The barrel was like $15, Stock was like $30, spring is like less than $15. With $4 shipping you can't go wrong. I did the bearing mod on mine, and changed the adjuster screw, but had to back out the adjuster screw as it was too hair trigger. (It also would fail to cock some times). Pretty easy to find parts for them, I ordered a bunch of commonly used and parts, ( seals etc.), from Crosman and found it to be useful to keep them handy.
I don't have a crony, so I couldn't tell you how fast they are going. they seem to penetrate as well s my Optimus and that is a stock Crosman spring rifle. I mostly shoot CPHP in it as they are cheap and resonably accurate in about every pellet gun I own. Most of the pellet guns are rated for alloy pellets and from what I have seen on here most of the generic stock springers shot in about the FPS you state. I have a few heaver pellets that I use mostly in my pump pnematics and they seem ot owrk better in those guns. I am actually trying to bring down the speed on this Tac 1 and make it a little easier to shoot. I have looked at most of the springs that Crosman uses in their guns and they seem to be all the same part#. I'm thinking of Gas ramming my Optimus and using the spring guides from it in the Tac 1 and see if a shortened spring works well in it. If it doesn't then I will have a spare spring to put back in it. This is going to be fun testing this out, and if it doesn't go as planned I will still have a useable pellet rifle.
