Sparrow after first 1000 rounds

[wally]

Here is my disassembled Sparrow after its first 1000 rounds, the recommended cleaning interval:

I'll probably be taking it apart for cleaning after every other outing, about 800 rounds.

Ammo was Federal Bulk pack from Walmart.

I think it would have been really difficult to pull the core from a one-piece tube, so I suspect that simpler design would need much more frequent cleaning and/or using cleaner (more expensive) ammo.

Should be obvious why your really don't want to shoot .22lr through a 5.56 suppressor that can't be disassembled for cleaning.

That is a LOT of lead and powder buildup on the blast baffle and tube parts.

How's the sound reduction?

Great, I was shooting steel plates without hearing protection, until someone started shooting .45ACP in the bay next to me -- was too loud so I had to put my ears back on.

The bullets hitting the plates is way louder than the gun's report.

This is my first experience with a .22 suppressor, so I can't say if its a lot of fouling or not, but I thought I'd show what it is.

Guess it goes to show you how dirty .22lr really is.

Is their any change in point of impact with the Sparrow? Mine shoots two inches left at seven yards.

I've used it on our Walther P22 and Ruger 22/45 (the "new" model with threaded bull barrel. Shooting steel plates at 10 yards the sights on the P22 seemed the same as without the suppressor. The 22/45 has a red dot that I'd adjusted prior to getting the Sparrow and it needed no adjustments using the suppressor.

Our plates are set up so you need to hit the top third or they won't generally fall so I'd have easily noticed any significant change in POA/POI.

My Gemtech HVT-QD had so much POA/POI change on my Draco SBR that its not really usable for me, whereas the shift on my RRA and DPMS rifles was about 2 moa, up on one, down and right for the other.

What are you using to get the lead off the suppressor? I was thinking of putting my Sparrow in walnut viberator and let run over night.

Make sure your threads are concentric to the bore. Put the suppressor on, and look down from the chamber to the muzzle and see that there are no "shadows." Everything should be strait and centered.

Sounds like it's possibly a little off center causing baffle strikes/deflection.

If that was the case, I doubt the can would last long enough for the change to be repeatable...

 

[rjrivero]

Not entirely true. If it's just a little off center, the bullet could be just grazing the baffle. It'll introduce yaw and the bullet path can be off pretty consistently.

 

[Saakee]

Nice pic. At first I thought you had cut it in half and I was shocked until i finished cycling down.

 

[bamawrx]

If the threads are off the bullet can "follow" the baffles. There have been some dramatic examples of this documented. Its a little hard to believe but it does happen, and so it could produce results like this. Best test would be to put the can on another host weapon and see if it causes the shots to go off. The point is that you don't have to get baffle strikes to move the POI.

I have one of these and it works perfectly across three hosts. Mine doesn't get as dirty as the original post, but I shoot mostly Winchester subsonic's. Wicked quiet with this ammo, and if you add a little water you get Hollywood quiet results.

I just let it soak for a while in penetrating oil and then scrape it off.

 

[PBR Streetgang]

I read on another forum that the owner had his baffles anodized and it made it easier to keep clean. I'll look to see if I can find the post again and give you a bit more info.

Is not that big a deal after a little soaking in the penetrating oil. It just pops off in big chunks.

Anyone toss the sparrow internals into a sonic cleaner? I have one and it cleans the heck out of whatever you toss in, but you can get some finish damage to some items. My concern is the end cap that is aluminum.

 

[Saakee]

Use plastic coated wire so it's submerged but not resting on the bottom so it won't be smacked around?

Based on experience I no longer clean aluminum in a ultra sonic cleaner.

Live and learn.

The new sparrows are all stainles steel.

I've had no shift in impact with the Sparrow on a Ruger 22/45.

It was my understanding that the baffles are stainless steel, but the rest of it is made from aluminum.

 

[plunge]

According to silencerco and all the reviews I have read it is all stainless steel besides the 2 rubber o-rings and is dip safe.

 

[Gato Montés]

The monocore, clam shells and I believe the endcap are all stainless. The outer tube is just regular old steel with a park finish. I don't know how well regular steel will hold to an ultrasonic or the dip, but given the design you shouldn't have have to do any cleaning on that part at all less a couple wipes with a rag.

 

[plunge]

I just searched again and all parts besides the outer tube and o-rings are stainless and dip safe. The outer tube is plain carbon steel and should not be dipped, but it really shouldn't need it because of the design. That was posted by Gary Hughes the national sales rep for silencerco. I haven't dipped my sparrow and don't really plan on it but you can. I just soak mine with cleaning oil and scrub it with a brass or nylon brush and all the carbon comes right off.

 

[Gato Montés]

^^^Echo???

I haven't received my Sparrow yet, but I looked into the many different ways of cleaning and while efficient, the dip kinda scares me.

Skin permeable lead as a byproduct? Eh, I think I'll go with the ultrasonic.
