Adjustable gas blocks

[montana]

Having used and evaluated many adj gas blocks through out the years I have a pretty good perspective on their strengths and weaknesses. I take a different approach from many by preferring to monitor the gas to control BCG velocity, while using the lightest buffer possible to mitigate recoil impulse. The common opinion is to use an H or H2 buffer, but the down side is the heavier the recoiling mass, the heavier the recoil impulse.. I have my favorite adj gas blocks as others, but my opinion has always been based on the quality, performance, ease of maintenance, ease of repair, ease of adjustment and effectiveness..My favorite for a long time has been the SLR, but they are not perfect and have the same weakness as the others I have tried. The common weakness has always been the springs, accessing the adjuster with a tool and the ability to repair and replace parts. Every gas block I have used that has a spring will eventually fail, including the SLR leaf spring..The SLR leaf spring has held up great compared to the coil spring designs I have used, but they will fail with a high round count. SLR has always replaced their parts and even the entire block for free when this happens, but I always wished there was a better option.. I have recently discovered a new design I'm going to be testing called the Rifle Speed that looks like a game changer..It is quite expensive and needs a proprietary straight gas tube, but takes a different and a better approach to adj gas blocks in my opinion. The simplicity of the design and maintenance may well be the adj gas block I have been looking for..With the Rifle speed adj gas block, there is no need to carry an allen wrench or other tool for adjustment. With this design it is easy to access for quick adjustments for ammunition changes, cold weather or when using a suppressor.. Of course when using any gas block the importance of the QC and fit with the barrel journal is a major concern, so I will be testing this new adj gas block this year and will give a summary of my findings...
