Here’s a deep dive / review / look into the USPSA Open Division race gun that I’ve been shooting for a year now. It’s built a decade ago by a local GM. I bought it used from a fellow shooter here in the PNW. Here’s the breakdown :
DAA Foldable Jet Wings
KIDD Blast Shield
38 Super Comp Ultimatch bull barrel
SV (Old STyle) Compensator
EGW Extractor, ejector & lockwork
SV Frame with stippled polymer grip
Infinity TriGlide widebody trigger bow
Infinity long flat trigger insert
Infinity round commander hammer
SPS magazine 170mm (w Grams guts & 4mm bolens) 29rnds
SV Magazine 170mm (w Grams guts & 3mm bolens) 29rnds
STI 140mm (w Grams guts & 7mm bolens) 22rnds
had two Stovepipes in my recent match at the Custer Sportsmen’s Club last week and was wondering what was the problem. If you look closely at this video, you can see occasionally the rounds eject downwards and not up and out.
That led me to think that it was hitting the scope, but according to John from JPL Precision, the Serendipity scope from C-more never has this problem and has worked fine for many of his guns.
I took a deeper look at the scope mount and I realize that my gun’s right side mount was cut to make more room for the round to eject. This was a 10 year old gun and was made by a not-so-reputable gunsmith (although John made it work better). As you can see from this picture, the Double Alpha Foldable Wing that I installed is slightly bigger and protruded almost a 4mm out from the scope mount, if you look properly, it has been cut to make more room for the round to eject.
The foldable wing on the left side sits flush against the scope mount but the right side was modified. It didn’t even occur to me to check that. Flipping the wing over, I notice dents and peening caused by rounds hitting the folded wing. so THAT’s what’s causing the stovepipes!!
Since the wing on the right side is useless, I took a saw to it and cut it off.
Touched up using some Birchwood Casey Aluminum Black Metal Finish.
and how it looks installed :
Perfect! now I’m ready and confident that there will be no more stovepipes
This time I was running a little too fast and pushing myself to find my limits. Blew through a port with 3 static targets supposedly shooting 6 shots but on the last shot, my trigger finger froze momentarily. My mind has already sent instructions to my finger to fire 6 shots, reload and move to the next position so I was already moving to the next position when my finger paused and in a split second, it continued. that caused me to let the 6th shot off into the berm.
the RO called it an accidental discharge and DQed me which was faire. Here, checkout the video for yourself
Have you guys had your trigger freeze and then continue like that?
