I’m currently looking at the vortex viper and venom for uspsa comp. Can anyone suggest a 24.1mm x 18mm window(viper) over a 26.4mm x 16mm window(venom)?
i would think the wider window would be better for transitions but I’m currently running a PA microdot with about a 17mm window...so either of these 2 will be an improvement.
thanks

I have one with a NFA Glock lower, 2k rounds thru it. No issues. I was initially wanting the NFA side charge upper but for a 200.00 savings, picked this one instead.
Also, where the charge handle is positioned, it ends up being a perfect place for a repeatable grip.

QuoteWith most hiperfire triggers, our selector switches will not work. We have only heard of the 24 3G Trigger working well with our selectors. It will stick out 6.21 mm away from the receiver surface.Best,Albert P.Product Dept.- Product Specialist

Just got back from testing a few loads. All out of a 16 inch barrel, 1.16 OAL, averages out of 10 rounds.
124 gr xtreme round nose
3.4 g titegroup 1047 fps
3.6 g titegroup 1114 fps
4.3 g power pistol 1076 fps
5.1 g power pistol 1222 fps
5.4 g power pistol 1251 fps
4.7 g wsf 1204 fps
147 gr xtreme round nose
4.5 g power pistol 1052 fps
To me, titegroup shot better than PP. Seemed to cycle a bit faster and a tad quieter. WSF, I thought was the loudest of the 3 powders. I will be refining some of these loads and retesting again, but thought I’d post these up if it helps. YMMV

I have a joe bobs/nfa lower. I just measured mine and at the bottom of a standard 33 round Glock mag, I have 1/4 inch play back and forth. Same with my ets mags. Bullet presentation does change a bit.
I placed a .034 thick shim on the back of the mag and got the movement down to 1/16th inch, but mags will not drop free. I’m assuming there has to be at least some play in the qc10s and jps.
I have 2k rounds+ thru this gun and had no feed issues. Even shooting a couple uspsa and 2 gun matches with a MBX mini extension.
