Bulldog Upgrades.4

We decided to make another 4th page to Bulldog's upgrades because the first one was becoming too long and as you will read, a day after trying the new suppression system, we found out that the DonnyFl adapter is not a complete reliable one. Thus we will paste here what we wrote before, and will keep adding more in the future, as this in fact is a developing job, not yet finished.

A few months later...

We just ordered another option to quiet the Bulldog.

There is an adapter offered by DonnyFL which gives you the option to use a detachable suppressor. It makes it easier to remove and put it back, and even though we have not received it yet, it is not plastic; it means should be more accurate.

It is a pity (not a wise idea) he uses M18 x 1 for his suppressor's thread because it means you suppose to buy only his suppressor; however, we found an adapter that we would like to try also from Hughes Precision LLC which takes M18 x 1 to 5/8 24, and we will try that one, even though we think we will need 5/8 18-male for our suppressor. To be used with the same suppressor we have in the .357 cal. Recluse made by Neil Clague; but we'll give it a try; otherwise we may end later on, after all, buying the DonnyFL suppressor, and then will count the $200 spent in the plastic pitbull suppressor as a kind of 'donation.'

Received both adapters. The DonnyFl was not tight enough, like 0.039 inch (1 mm) gap, short all sides. He just sent a second one as he confirmed it was due to a faulty batch; thus should come next week. Also took notice that I see the factory adapter has an opening (ID) of 0.46 inch (11.7 mm), but DonnyFl has an ID of around 0.424 inch (10.78 mm), which is significant less. It means that if you add the gap of 1 mm all around the shroud it can produce a dangerous miss-alignment for that slug coming out.

The Hughes precision one was of a good quality, but the only closest thread they have was  5/8-24, and as said we actually needed 5/8-18; so Neil Clague is making us a new adapter. He is a heck of a machinist making suppressors for many years.

Received the replacement adapter from DonnyFl. This one is better, but still have some gap and play. The good part is that the screw holes line up with the ones in the factory's shroud and once tightened, by theory it should be aligned with the barrel; however, as the inside diameter is smaller than the factory adapter, we are going to shoot it first without any suppressor... just in case. Then we shall add the suppressor, which we are still waiting for the other adapter made by Mr. Clague.

This Bulldog adapter made by DonnyFl is a starting-point-good-idea; however, we think the best one yet to come, will be one that on the inside will reach all the way into the barrel. Then what you can add is holes in between the barrel and the tip of such adapter, and that way gases will leave back towards the shroud, even helping the suppressor as well. The way that is now + the smaller ID could bring bad news at some point, because the barrel without really tight supports can move in different ways, and due to many reasons, even just a hair of shaking like when you are shooting continuously. 

Take in account that all this headache is due to the way Crosman designed the shroud system for this particular rifle. We added in the past the Pitbull barrel supports, but are in the process of putting them in a drawer as we ordered a couple of the factory ones type which are much better. They are just $2 and some cents each, and all you will need to do is finish to round the inside diameter by cutting off just the tip on the longer side, which has a stop, with the original intention of staying in the end of the barrel.

Another thing that Crosman lost the opportunity to make money is by lacking the chance to replace the reservoir, the same way Hatsan and other brand rifles do. They would have sold many spare ones and at the same time customers had been satisfied. We do not think it is a good idea enlarging the current tube with a second part/addition, even having inside two different pressures, as I have heard. It is like you are almost planning a time-waiting explosion, specifically if you are going to use it much (just an opinion) by logic, not based on testing. Knowing thus, that more issues could show up, like for instance stop working/fail in the middle of nowhere. 

All of this shows that the Bulldog has a path to go, and for now it may be better to keep it the way it is; and if you want a more sophisticated one, instead of spending $$$ or buying it, just get another rifle with all other options. If not, at the end you are going to spend almost the same as getting the one with all the features. 

Of course, like us, you probably already bought a Bulldog and want to improve it.

As you can see in the next pictures we received the Neil Clague adapter and it fits perfectly into his .357 air-rifle suppressor and the DonnyFl adapter. The trying part will be to check if Donny's adapter shoots in the Bulldog without any major issue. We will try it on in the Range this coming week, and post it here.

Jumped quickly into the range at sunrise today.  Shot 12 times with a flat DrillDog Big Bore Pellet 95 gr, and round 126 gr... everything was fine while leaving the suppressor on its own (not resting it on any surface, etc). Now we are able to have one good backyard-use-friendly suppressor for two air-rifles; however, we can see that there is still some play (gap) in Donny's adapter if moving the suppressor to the sides by hand, or hitting any bush or related if in the field. It means it could give us a surprise in the future, and as we said before, this is just a good idea that needs further development. The barking is even less than the one we posted in the Recluse's page. 

In the future we will do further tests.

The suppressor originally has 5/18-18 ID thread because it was made for the Recluse we have; but I am pretty sure you can tell Neil Clague, to make it for you directly to fit the M18 x 1 thread; and thus you will not need an adapter like me. Remember to tell him you read it here, that way he will know the type of rifle and suppressor you are talking about, as he's been busy these days and we are not sure if he intends to make this one again. 

This all will be at your own risk, taking in account the side-play Donny's adapter still has in the Bulldog's shroud tip till a fix is provided (or you do as you will see next), now increased due to having a long suppressor; but it is the only way to really make it suburb backyard friendly (88 db), which by no means is close to silent; however, in comparison as without the suppressor, it is really a big difference. We were not able to shoot it at home without a suppressor. 

A short suppressor will not be that effective (just my opinion), no matter what made-up reviews have been published in order to have more sales... this is a .357 caliber air-rifle. It pushes a lot of air through the barrel.

If not touching-hitting anything, the whole thing (adapter + suppressor) will remain straight as we just tried; and we are going to add one layer of some tape on the sides of DonnyFl's adapter to help in keeping it as tie and aligned as possible... Keep reading.

Said that, next good move will be creating an adapter that reaches the barrel, either of this type, or threading an enlargement to the barrel with holes along the way. It will be the only real complete fix and fit, if wanting to add an all time reliable suppressor system to the Benjamin Bulldog air-rifle.

My temporary solution to the gap issue has been adding electrical tape on the sides of the adapter, and after that it seems quite better in place. Take in account that in the next picture you are going to see tape going all around. It was just the first time we tried, but it was too much. You will need to add only one layer on both sides, not on the top or bottom, which is where the screws hold it to the shroud. The thread you see in the other side of the adapter is just the other suppressor adapter we got in order to convert from M18 x 1 to 5/8-18 suppressor's thread that I'll keep it permanently on.

http://www.drilldogbigborepellets.com/p/bulldog-upgrades4.html

Following the taping part, I emptied the Bulldog's reservoir just as a precaution, then removed the shroud. Next took two of the barrel support we ordered from Crosman and cut them off on the larger side, then with a thin sharpened carving chisel removed the inside little plastic ramp made from factory to grab the flat front top of the barrel. You can drill inside too for a perfect diameter, but as it is not much, if done carefully, it is not necessary.

Once out of the barrel and upon inspection I found one of the three Pitbull 3D thin plastic aftermarket supports I had installed months before, was already completely cracked; and the other two on the same path, cracked in the inner circle. This was certainly affecting accuracy as well.

http://www.drilldogbigborepellets.com/p/bulldog-upgrades4.html

Then when having the factory ones ready, I used some WD-40 on the barrel's surface (you can spray a different one) to help in the process of pushing it through the barrel till reaching the desired distance between them.

http://www.drilldogbigborepellets.com/p/bulldog-upgrades4.html

Once done, now I have real supports. They are tight, will not be wandering along the barrel, thus stronger than the aftermarkets ones; and will do exactly the same as the one in the tip of the barrel which comes from factory, in order to hold that barrel in place. See attached picture with the three of them before re-assembling the rifle.

After this we shot five more times in our backyard, and it seems all is fine with no sign of miss-alignment... at least for now.

Here next, the Benjamin Bulldog without suppressor, in our case with two adapters: Donny's + Neil's with cap. As we said before if you order from Neil, you can tell him to just make it directly to DonnyFl's adapter's thread; because in our case was different due to wanting to use the same suppressor for two air rifles.
