Spikes tactical adjustable low-pro gas block - Spikes Tactical Adjustable Low Pro Rifle Gas Block

I'll Be honest - I haven't installed this on my rifle build yet so I might see if I can do a follow up review, but I can tell you from just seeing/handling the part that it is built with the utmost quality. This "Spikes" gas block is actually just a re-branded Superlative Arms part. They (both) are known for robust quality and innovation - two of the reasons I chose this gas block over a myriad of others available. The other primary reason I selected it is the proprietary "bleed-off" valve that bleeds off excess gas as opposed to dumping it in your receivers/boltcarrier group. Like I said: we'll see how it performs when my build is complete, but going by these two companies reputations - I'm sure it's going to function as awesome as it looks and seems to be built!
