Catch 22 AR-15 Bolt Catch?

[AbrahamBurden]

Does anybody know how the Catch 22 bolt catch for 22lr AR-15 uppers is? How does it perform the last round bolt hold open function with Black Dog magazines? How does it compare to CMMG's BHOA adapter?

I have 2 Catch22s BHOs
They work pretty good with M&P 15/22 mags and tape.
The thread on Arfcom is gone?

Have not had a chance to try out new CMMG or BD mags with different followers
to see if it works.
I have old BD mags.

Compared to Cmmg BHO...Not the same.
IMHO.

CMMG is finicky for set up and requires the MAGS have the correct
follower.

I gave up trying to set up my CMMG BHO...Some other day.

Once installed...your lower is strictly a .22lr lower and you
will have to remove the C22 for centerfire.

The dedicated 22 lower is not an issue for me; I plan to make a dedicated 22lr AR-15 anyway. If you do ever test the Catch 22 with Black Dog magazines, can you tell me how it functions?

Black Dog is working on compatable followers for the Catch 22.

The CMMG BHOA almost always requires the bolt catch spring to be shortened or the reduced power bc spring for proper function.
The mag spring has to overcome the Bolt Catch Spring.

Thats what Im waiting for.

they are different generations of BD mags out there.

Seems I bought the
WHO KNOWS WHAT GENERATION
BD MAG to replace my worn out ones.

Steel feedlips...Skeleton body design with
pull down follower.
Easy loading....
But it does NOT LOCK ON LAST ROUND FIRED.

One day Ill get lucky and find the correct generation
that works with it.

To bad the Catch 22 thread on ARFCOM dissapeared.

It stopped being worth the cost to advertise on AR15.com and when you stop being an advertiser they delete all your threads :-/

The Black Dog magazines do not work with the Catch22 even though they say it does. The follower doesn't go up high enough and the spring tension is way too weak.

Right now the best solution is the S&W 15-22 magazines with the adapter I sell that makes it fit snugly in the AR magwell (apparently the 15-22 magwell is a little smaller than standard).

If you have any questions please respond here or shoot me a PM.

Thanks,

With your product installed on the lower, does it make it impossible to run a centerfire upper on it?

With all my uppers and everything floating around... I'm kind of thinking I'd like a way to make my lowers intended for rimfire not compatible in some way with a centerfire upper.

[alpalwal]

Sorry for the delay-

Thanks. Do you have an ETA on Black Dog's compatible followers?

Nope. It's been a real pain getting them to make any changes. Hopefully soon but who knows.

Yes, this is only compatible with .22s. With a centerfire upper, it won't even close because the bolt sits too low and the bolt catch hits it.

The Smith & Wesson 15-22 magazines work great with the Catch22 bolt catch but by themselves they don't fit snugly in standard AR-15 lowers. By putting an adapter on the front of the magazine, the magazine will fit snugly in the lower and consistently engage the bolt catch after the last round is fired.

Since we also have an M&P 15-22 we want to use our magazines in, what about shimming the magazine well itself? Again, dedicated .22 lower (with a normal magazine release ). Any issue with that?

Does the catch 22 bolt catch come in black finish?

Honestly I haven't tried it but I don't see any reason why it wouldn't. I might sand down the bottom end of the adapter first though so that the magazine can slide in easier and you won't have to worry about hitting the bottom edge of the adapter.

Yes, they all come parkerized black.
