Have always had issues with most light target ammo in my 930 Tactical.
With the 18.5" barrel, the gas system has an even tougher time properly cycling low recoil and light loads than the SPX models that are notorious for stoppages. It chews through most any HD loads, slugs, buckshot, etc. but when the muzzle velocity drops down into the sub-1300 fps range it quickly becomes a single shot and the bolt has to be manually operated to extract the spent shell. This can be particularly frustrating and has severely limited my use of this shotgun for competitions and club matches, many of which only allow #6 or smaller target shot.
Enter the OR3GUN Marine Spacer Tube...

For anyone unaware, the good folks at OR3GUN became a site vendor here on the forum a while back and I have followed their progress as several members started using their products. After a few glowing reviews I decided to give it a try in my extraordinarily ammo sensitive 930 Tactical...
Installed the OR3GUN Marine Spacer Tube a few days ago and made it out to the range this morning with an assortment of ammo to put it to the test...
Pictured above from left to right:
1. Federal #8 Target Load - TG12 8
2. Winchester #8 Super Target - TRGT12M8
3. Winchester AA #7.5 Light Target Load - AA127
4. Estate #8 Dove and Quail Load - GTL12XHN 8
5. Remington #8 Gun Club Target Load - GC12L8
6. Rio #8 Target Load - TLT328
7. Rio # 7.5 Game Load - BG2875
8. Rio #8 Elite Target Load - RE328
Detail stripped then thoroughly cleaned and lubed the 930 Tactical last night to start off with a clean slate. These rounds were selected to test based on a personal history of virtually 100% failures in this shotgun with the factory spacer tube. Spent the morning working my way through all 200 rounds...
Took me nearly as long to clean up as it did to run through them...
I shot seven consecutive rounds of each type at roughly one second intervals to start. Next, I loaded the tube with one of each alternating rounds at random and shot using the same cadence. This was repeated until I had shot at least four of every round. After that, I went back to using a single type in a full tube and emptied the tube as fast as I could. Here are my results by ammo type:
1. Federal #8 Target Load, TG12 8 - zero failures
2. Winchester #8 Super Target, TRGT12M8 - 24/25 FTE, 96% failure rate
* These failures were all completely failed extractions. The bolt would only retract about half way back, then re-chamber the spent shell. The shell stop did not disengage and the following round would not enter the receiver.
3. Winchester AA #7.5 Light Target Load, AA127 - zero failures
4. Estate #8 Dove and Quail Load, GTL12XHN 8 - zero failures
5. Remington #8 Gun Club Target Load, GC12L8 - zero failures
6. Rio #8 Target Load, TLT328 - 15/25 FTE, 60% failure rate
* These failures were partially failed extractions. The spent shells were caught between the bolt and chamber (stovepipe) with the following round jammed below them on the lifter.
7. Rio # 7.5 Game Load, BG2875 - 5/25 FTE, 20% failure rate
* Just like the Rio Target Load above, these failures were partially failed extractions. The spent shells were caught between the bolt and chamber (stovepipe) with the following round jammed below them on the lifter.
8. Rio #8 Elite Target Load, RE328 - zero failures
When the smoke cleared and I was out of ammo, the OR3GUN Marine Spacer Tube had yielded a 78% reduction in the number of failures with this selection of ammo in one of the most ammo sensitive 930 models on the market. I consider that a HUGE win, considering I could not use any light target or game loads with the factory part. Now I have an assortment to choose from. The testing will continue and I will post back here on any further findings with additional types of ammo.
@OR3GUN ,
Thank you for this outstanding upgrade. Your time spent on research and development will help countless shooters improve their performance and relieve a LOT of frustration dealing with ammo related stoppages.
If anyone here on the forum is having these issues or on the fence about this product, order an OR3GUN Marine Spacer Tube today. This is hands down the best money I have spent on any part for my 930...
