Airgun Guild Forum Announcements / 1720 NBH
« on: April 13, 2017, 09:11:53 AM »
Travis, I'm building a 1720 regulated carbine and I'm not seeing Prod/1720 NBHs on your site. Still make them?

Airgun Hunting / Lucky trophy!

*Magpies are protected birds but, in my state, they can be removed as pest birds if they cause agricultural harm to a business or private person. My next door neighbor is a wildlife official and has confirmed that the magpies around here pick through our freshly planted gardens in search of seeds.

I was at my parent's house this morning since I got off work early and had no school work to do. I figured I could hang out for a couple hours and try to get a bird or two with my new QB79 carbine. I've been out twice since I've got it together, but it's currently shooting at 6.5 fpe, so I have to keep my shots 20 yards and in until I can get the regulator bumped up enough to get to my goal of 12-13 fpe. Like I said, I've been out twice since getting it together and I've seen multiple targets each time, but nothing in range. It's especially frustrating because my buddy popped the birds we saw with the 12 fpe XS46 that I sold him. Anyways, I digress.

I hadn't seen anything and I'd been sitting for a few hours, so I decided to pull the breech and tube plug out of the gun to see about adapting the gun to fit the really nice, brass Benjamin Discovery power adjuster I have sitting around. As I'm sitting there fiddling with the parts, I look into the backyard and there are three magpies sitting in one of my parent's fruit trees. I scramble to get the gun back together all while hoping these magpies don't fly away. Just as I'm getting the stock back on, they all take flight. Two go and sit on the horse fence in my neighbor's yard and the other lands in a tree on my opposite neighbor's property.

My parent's have a decently large plot of land, but they still live in suburbia, so the only safe shot I have is with the bird on the ground so I can send the pellet through the bird and into the ground. I know magpies are corvids and corvids go crazy when their distress call is sounded, so I loaded a pellet and pulled up YouTube on my phone. I found a magpie distress call video and played it with the volume all the way up. The magpies went crazy! They flew around trying to pinpoint where the distress call was coming from. Finally one landed in my yard, but I didn't have a clear shot from the window I usually shoot from. So I shut down YouTube and headed to a window on the opposite side of the house. I got to the window, cracked it ever so slowly, and got into position. The magpie heard the window sliding and stood at attention. I had him at about 18 yards away, so I held right on his head and let the pellet fly! The magpie jumped about a foot in the air and landed on its side. After a little death dance it was done for.

My first kill, with what is definitely my favorite airgun ever, was a personal trophy for me. I only get one or two magpies a year here in suburbia. And this magpie is easily the biggest and most colorful magpie I've ever gotten!

PCP, C02, and Helium Powered Airguns / My QB Build
« on: November 15, 2016, 05:51:38 PM »
Hey all, I wanted to make a thread about my first time doing a QB build. First a little backstory. I started with PCP airguns in Spring/Summer of 2014 with a Disco that I ended up spending way too much money on. Since then I've had 7-8 other PCP rifles. Some quite powerful, some detuned to under 12 fpe.

After spending several thousands of dollars in the last two years I've sold every PCP I've owned. I've decided I'm done buying guns. I sat down and decided what I really need in a PCP. What PCP would truly make me happy.

I decided on several parameters that the gun must meet. Those parameters are:

1) Must be under 40" long, including LDC/shroud

2) Must be under 10lb scoped/bipod

3) Must be regulated

4) Must get 50+ shots

5) Since 99% of my pesting is done on pest birds within 50 yards, I don't need anything over 15 fpe in .177

6) Must group no bigger than .704" CTC (size of a US dime) at 50 yards

7) Must look sexy

8) All this for less than $1000

So, I came up with this QB build. My goal for this .177 QB build is 175-200 regulated shots at 12-15 fpe. I plan on shortening the barrel so the LDC will almost butt up against the air tank to keep it as short as possible. I plan on getting a LW barrel machined for it if the stock barrel is not up to .704" CTC at 50 yards. I'm going to inlet a thumbhole AR2078 stock for the 79 and hopefully that will provide a sexier look than the plain stock and bottle hanging out in the front.

So here's some pictures of the progress so far.

Set up an old table I found in my dorm room (much to my roommates chagrin ;) )

Here's a super exciting shot of the unboxing...

Gun out of the box, tools on the left, other parts for the build on the right

First removed the sights

Pulled the stock off and got to working on the action

O-rings don't seem too torn up on the tank block. Still going to replace the o-rings and deburr everything

And I got excited and forgot to take pictures, but here's the action all torn down and sorted into labeled baggies

Next up is for me to go buy some diamond grinding bits for my Dremel, some silicone grease, all the proper o-ring sizes, and several grits of sandpaper. I'm going to meticulously go through to deburr and polish everything. I will take pictures and keep the thread updated.

While I have owned a QB before, I've never broken one down. First impressions are that it is overbuilt! There is no plastic in this gun as far as I can tell. The only other gun I've had experience tearing down and modding is the Disco. The QB has a lot less small fiddly parts than the Disco. Plus the breech screw is the polar opposite of the POS screw in the Disco. So far I'm loving it!

Wicked Air Rifles (WAR) / Bottle kit for Mrod
« on: August 08, 2016, 12:28:43 AM »

I was wondering if/when you'll get the bottle drop down back in stock? It looks like you have the shortened air tube and 500cc bottle in stock, but no drop block. I've got an Mrod that is regulated to 30 fpe and will shoot sub 1/2" out to 50 yards, but only gets 30 shots on a fill. I think this gun getting 65-70 shots a fill would really take it up a notch.

Ask Bob / Moving bell curve to lower pressure
« on: August 04, 2016, 12:39:54 PM »
Bob, I read that if one were to increase transfer port diameter while simultaneously reducing valve dwell, the power will stay the same but move to a lower fill pressure. If I don't want to mill the hammer down to a lighter weight, can I use a stronger valve spring to reduce dwell?
