New Compensator ?

Recommended Posts

I have an old tacsol Comp on my pistol the one with all the tiny holes and it’s a pain to clean 

have a similar one on my rfro

I was looking at the Alchin Comp just has two giant ports and looks easy to clean I would like to try it 

my questions are 

 

1. Will it clock rite ? Or will I need additional washers ?

 

2. Has anyone made the swap on a pistol or rifle and how do they like it or did you even notice a difference?

All of the large port comps lead up with any 22LR ammo.  It's just something you learn to live with.  The Alchin come with a crush washer, so it will clock.  However it may not stay clocked.  A better bet is a Maddmax Precision Tactical comp.  They always clock perfectly after adjustment.

I only use Allchin comps. They are great and easier to clean than the TK comps. Mine came with o-rings so it’s very easy to set.

 I want to get away from the small ports on a Comp so all the maddmacs seem just like what I have want Big ports so I can clean it out easier

John Allchin parts are the best of the best. I have 2 of his comps. They came with a couple of different washers to assists with th he proper alignment.  Dont hesitate. Order one now.

I had an Allchin comp.  It worked, and it was an absolute PITA to clean because the lead just stuck right to the rounded aluminum port.  I’m using a Pace Setting Design comp now and it’s super easy to keep clean because it is coated with something the lead doesn’t like to stick to as well, and the lead also tends to fall off it when it shrinks after it cools down.  Yes, I still have to clean it, but it’s way easier than the Allchin.  And it’s good looking.  If interested let me know, and I can get you the PSD contact info.

I have the Allchin comp on my Mark III.  I was remiss at cleaning my comp but finally decided to get the lead out.   It was easier to pick it out of the Allchin then a number of other comps I've tried. I found that soaking it in MPro-7 overnight helped loosen the carbon and made using a brass pick easier.

take the Comp off your rimfire pistol/rifle .... they are not needed, (I did extensive testing to prove this to myself) and as you noted are a pain to clean & do affect accuracy if you don't clean them regularly.  Neither my RFPO or RFRO have comps on them ...

They may not be needed but they make them louder and that helps the timer. We had issues at Area 6 last weekend with timers not picking up shots.

I'm curious if anyone knows if you (on a rimfire pistol) drill out the hole in the comp, just make it bigger, would it give you a louder bang and not have any negative effects?

 

I ream the innards all the time with a drill bit but was thinking about enlarging the exit hole. Anyone see a problem with that?

I agree that it definitely helps to pick up the shots 

plus it looks good 😎

Just an unscientific guess, but I think it wouldn’t hurt performance at all on a rifle if you srilled ot out, either as a muzzle brake or sound amplifier.  For a pistol, I’d experiment with it on and off and measure results.  If it shoots no different without the comp, then drill it... or just leave it off completely.   I think an uncomp’d pistol would be picked up by the timer just fine.  

 

For a rifle, the comp is extremely helpful for getting picked up by the timer.  If you’re using a CED7000 or similarly sensitive timer, it’s a nonissue, but as a competitor I can’t pick and choose what timer the RO decides to use.  If not for that aspect, a rimfire rifle comp is unnecessary weight and I wouldn’t use one.  If you’ve ever had to reshoot and reshoot and reshoot because the timer wouldn’t pick up the shots, though, you’d undestand why I suck it up and run the comp.  Reshoots affect the mental game worse than the weight of the comp affects the swing.

Regarding comp performance (or lack of) on rimfires, there's a ton of opinions and I don't want to debate here, but I like this video from TK.

This is a great example of a bad "scientific" test. It only "proves" that if you hang more weight on the end of the barrel you'll get less muzzle rise. IF you want to see what the comp does, or doesn't do, try this "test" with the comp "clocked" normally, ports up, and then with the comp rotated 180 deg. Ports down. Muzzle weight will be the same so you'll see the ports' effect, or lack of effect. A comp with effective porting is also pretty amusing to actually shoot (no ransom rest for this) with the comp rotated 90 degrees so it pushes the muzzle sideways...

True, if this was done in an actual science lab, they would have done a third test with the muzzle brake replaced with a simple weight in place of the brake to rule out weight as being the determining factor in the performance increase.  And they would have fired all three way more times for a valid sample size.  I’m kinda sad that they didn’t do this, actually.  It would have been an interesting data point.

Think you guys putting far too much thought into a topic where everyone knows the comp is simply not to hear, “sorry man, the timer didn’t pick up, need to reshoot.”  It’s for noise and noise alone. The Tandemkross video is marketing to sell a product making the point the product reduces recoil, whether due to gas exit or weight.  Obviously this will be subjective to each shooter.  As to the OP question, they all clock correctly and Alchin makes some amazing products.  Have his 15-22 specific comp on my rifle and have never heard needing a reshoot cause of no timer pick up since.

Amen. As an RO I hate telling a competitor I didn’t get the time.

I'll have to disagree with you on muzzle brakes on rimfire pistols.  I have a 2 port comp milled into a steel 5 inch slab side Buckmark barrel on one pistol and an identical Buckmark sans comp. ie same barrel, no comp milled into it.  I have tested both extensively, including switching barrels back and forth between frames, over many practice sessions and matches.  I am several seconds faster over the course of the match with the comp.  It isn't much faster per string, but over 39 31 strings, it adds up.  Since the muzzle brake is milled into the barrel, the difference isn't from hanging a weight (brake) on the end of the barrel.

 

I will agree with you on the rimfire rifle, I did much the same with a pair of 10/22's, both with Tactical Solutions barrels.  One threaded with an Alchin muzzle brake and one unthreaded barrel.  No real difference between them other than one is louder than the other.

DOH, forgot about the throw away string

Yep. My rimfire rifles have comps just so the timer can better hear them.There's not enough gas pressure/volume left at the end of a 16" barrel for a comp to work. On a 4"ish pistol barrel it's different. With Hi-velocity ammo you do have enough gas pressure/volume for a comp to do something. Lotsa comps out there that do nothing but add weight and look cool. Some actually put the available gas pressure/volume to work. Easiest "test" is to shoot the gun with the comp clocked normally, then rotated 180 degrees. If your comp actually works the difference is obvious. No hi-speed photography required. If you can't notice a difference you have a comp that's just a barrel weight.
