Looks like I will have to get an adjustable gas block to control ejection in the AR. Once the screw is set
do they stay set or something you half to constantly adjust? Thanks Pathfinder20 |
| I got this one http://www.jprifles.com/buy.php?item=JPGS-SO from Syrac Ordinance/JP Enterprise. It has a lock. I haven't shot it yet but it looks like a nice piece. |

That gas block looks good, but will have to check and be sure the one I finally choose will fit under a Troy TRX Extreme handguard. Whats the I.D. of that rail?? I see both 1.3" and 1.5"  Anyways its a small gas block! 
The set screw version from Syrac is even smaller

The id of the handguard is app 1.46 dia with a groove under the rail app 1.78. From the two
drawings looks like only the bottom one would have a chance to fit. When I got the hanguard I had just cutdown a front sight gas block to fit a Yankee Hill quad rail if I remeber right. I had to get a low profile gas block to get under the Troy, but worth the trouble. Thanksfor the info. Pathfinder20 |
