I started my 20" flattop build

The only pump I ever owned was a Mossberg 500 Bullpup and I didn't like it. I've always been a fan of semi-autos. 19+1 rounds of buckshot in this gun should intimidate anyone who's close enough to see it, and who knows what it is. But the 12-round mags are easier to handle than the 19s. The 7-round and 12-round mags are easier to carry in pouches on a belt too. I have 3 of each size mag and 6 mag pouches, so I can carry all 3 7s and all 3 12s while there's a 19-round mag in the gun. And I can toss it on the ground when I reload, instead of trying to put it in a mag pouch where it sticks out in the way.

I finally replaced all 4 of my extractor and ejector springs with Tubb's extra-power chrome silicon springs. They should last the rest of my life, and the life of the rifles. The extractor springs are about 80% stronger than stock and don't use any D-rings around them, so I have 2 D-rings and 2 O-rings left over. And I replaced the extractor in my Can Cannon too, since it has my original AR-15 bolt from about 30 years ago. The bolt ejector tool I bought from Windham Weaponry made the job so easy I couldn't believe it. They don't sell it anymore, but it's similar to the SINCLAIR AR-15 BOLT VISE.

My ex-army co-worker, Marshall Dillon at Brownells shows how to use their AR bolt ejector tool. We used to do this using our hands and no tools other than a hammer and punch. We had to borrow a hammer from someone else, and made all our punches out of firing pins and guide rods and things in the shop. He was the only good worker I had out of 4, and I think we did 99% of the work. "Munchie" was always on a smoke break or grabbing a bite to eat from the Roach Coach. Part of the reason he never got promoted, and I was promoted 3 times until I was his boss. I wonder if he still hates me? "Heckle and Jeckle" weren't allowed in the shop. One of them had a note from the doctor forbidding him from touching a weapon, so he pushed a broom in the open bay outside the shop until someone needed him for something else. And the conscientious objector sat at a desk in the room outside our cage and answered the phone for me. I didn't trust him to fix any of the weapons our lives might depend on. I still think it was the right call. It was kind of weird having my own secretary, and a janitor too, when I was still a teenager. Then, when I got to Germany I was low man on the totem pole with no chance of being promoted over the other two guys. I did more than my share of the work there too.

P.S. I soaked a pipe cleaner with Hoppe's gun oil and lube the inside of the ejector spring holes before I oiled the springs and inserted them. It's the perfect tool for the job. Q-tips are way too big and I didn't even try using one for it. I have regular pipe cleaners, and extra long pipe cleaners for swabbing out the gas tubes if they ever get plugged up with carbon.
