I'm struggling to get my gun running. The tracers I bought don't seem to have enough balls to cycle the action all the way. It does eject and load a new round, but it doesn't cock the hammer.

Does the barrel length of a 22 blowback have an effect on the impulse imparted to the bolt?

What about different ammo?

Yep, that'll be my next step, but I was really hoping to use tracers.

I think I have a 3 pound recoil spring in the parts bin. I'll probably try that next.

To some extent.  The shorter the barrel, the shorter the dwell time.  But that's measured in microseconds, IIRC.

ETA:  Have you tried a Flaming Pig to add backpressure?

.22 rimfire can be very ammo fussy.  And don't overlook break-in and lubrication.

Get it to run with common ammo, then try the tracers after a thorough cleaning and relubrication.

Yes, you need a suppressor.

I have not. I'd really like to stick to this Han Solo form factor. I have two  12" uppers with Bore Buddy guts that absolutely rip and roar.

I think that's wise. I'll go back to Mini Mags.

Like, THE “you’re holding over $1,000,000 in your hand” original?

Elittlefield, I like your rings. Did the scope come with it as well? I am trying to figure the optic out. That stinks to hear about the tracers not working/cycling the gun. Have you tried other 22lr ammo in it?

Just got my DL-44 upper from Canto Arms. This thing is really cool, being a Star Wars nerd, (at least the original 3 movies). The Canto broom handle grip has much more comfortable gripping angle compared to the CMMG in my opinion. Now to take it out blasting.

The scope is from the Canto site. I also bought the rings they have, but they put the scope further out to the right than I liked. I bought these Chinesium ones from Amazon. I had to grind down the charging handle to clear the scope. https://www.amazon.com/dp/B07MH4P5H2?ref=ppx_yo2ov_dt_b_fed_asin_title

The gun runs on semi auto mode with the tracers now that I swapped in a Blue (3 pound) recoil spring, and I get intermittent bursts in Forced Reset mode. I'm waiting on a steel bolt weight body to finish tuning.

Seen it at a couple shops here. Me personally, I would go with a movie accurate DL-44.

There's an eBay shop that makes a nice, all metal replica of the DL-44 in several versions, like the DL-44 "Greedo Killer", thje "Hoth" model with the tank scope on it and the one Luke used in The Empire Strikes Back.

https://ebay.us/m/Ma993K

I'm sure none of us would butcher an original, just to turn it into a live firing replica... Unless you're Jerry.

As much of a gun/Star Wars nerd i am, I've never gone down this rabbit hole.
For all these years i only ever considered two variants, black and blue.
This was an interesting read.

Bump for personal reference. No new info. I'm going to try to get this working in FRT mode with tracers when Spring comes.
