New 16” spikes tactical 300blk carbine barrel
Posted: Thu Oct 14, 2021 12:51 pm
Just set up a new barrel with a carbine gas system on my old AR lower setup and it’s short stroking with 125gr Winchester open tip range
Barrel:
Spikes tactical 16” CHF MP 1/7 carbine CMV chrome lined
First of all, my gas block is perfectly aligned. I ended up moving the gas block and slow motion recording between tests and found it was placed slightly less than optimal but at the end of the day, the bolt only traveled nearly half way. The bolt slides smooth, no catching or tension other than when locking. I’m using a carbine buffer and spring. Full auto bolt carrier. 220gr subsonics move the bolt about 1/8 or 1/4 of the way
So… I measured the gas port and found it to be 0.0625 or exactly 1/16”. What’s going on? Did someone drop the ball ad just drill the wrong size completely? Even tho photo on the website (wingtactical.com) shows a barrel with a hole that looks larger than the one I’ve got.
Thoughts?
I ended up drilling the barrel to 3/32” or .093 and will take it out to the range when I can. I also ordered an slr sentry 7 adjustable gas block.
