Loop a piece of string around the trigger, and loop the other end around one of the user's teeth. He then jerks his head back and forth to operate the trigger. Voila!Also, a thought occurs; how do you plan to pull the trigger? The guard looks way too small for adult finger tips
Jokes aside, I think you make a good point. Judging from the pic below (and I realize his thumb is blocking it, so this is a guess), it looks like the only way the OP could get his finger into the trigger guard is if the trigger is held fully to the rear. Sort of like trying to shove both hands into one glove.
Don't know why you would, he's using a commercial barrel and logic would dictate starting with a heavy recoil spring/ buffer and working your way down until it cycles.I imagine when it comes time to shoot it, you'll be using the string-pull method with a single round in the chamber at least once.
Now I want to see the 20mm grenade launcher.
I was thinking a .410 rifled barrel, so it wouldn't be either an AOW smoothbore pistol, nor a SBS if done in 28 gauge or larger.Am I the only one who noticed the grenade launcher cut on the barrel?
With how small your project is will a 12ga size shell be too big for the launcher? If it does fit that looks like a GREAT option for the launcher...
Outstanding work. Just noticed you used a drill bit for the port cover rod. One of the most intriguing threads I've ever read on this site.A 12 ga shell would be almost exact for scale at 19.7mm, although the bore of the flare tube would be somewhat smaller, about 18.5mm.
I did get the bolt catch/extractor done as well. That was a really challenging piece to machine, lots and lots of operations on all sides, which meant detaching it from the stock early on. There was also the slot to cut in the bolt carrier, as well as relieving the upper for the extractor portion of it. Came out OK, though I did lose two more 1/16 cutter making the slot.
Plan is to cut a slot in the back of the mag and run a 0-80 or 1-72 socket head into the follower to engage the BHO.
