Clamp On or Set Screw Gas Block

[alx01]

Clint you have been one of the most reasonable and knowledgable members on this board contributing a wealth of knowledge. I'm glad to see someone as experienced as yourself express a common sense here. I see people are too focused on saving money often as little as $5-15 and maybe a total of $50 per rifle trying to score cheaper parts of either questionable quality or unknown blem issues. It's okay buying good quality parts on sale and/or cheaper. I personally stray away right now from any blem items. First of all - almost all blem items are non-returnable, second - it's not worth saving a couple of dollars on the part which you typically never replace unless there is an issue.

In reality, skimping anywhere in the gas system can cause issues.

The most common issue with cheap gas blocks is over sized bores for both the barrel and gas tube.

Loose bores cause excess gas leakage and variability in gas drive.

Over the years I have seen strap-on gas blocks come loose. One issue that seems to be common is the screws loosening and sometimes break from use. Ultimately, as Clint mentioned, an interruption of the gas system is going to lead to problems.

IG- if YOU were building a 20" precision rifle..what low pro Gb would YOU use? Even give a top 3 or 5 list if you want.

Admittedly, I do not put much thought into this. I have used Geissele, BCM, Centurion Arms and the SIONICS blocks we have made. I cannot recall actually have an issue with any of them. In fact, I can't recall the last time one of my rifles had a malfunction when shooting.

Of course all my barrels are dimpled and set screwed or pinned as appropriate. All my gas tubes are properly aligned and all my BCG's used tested and vetted components.

Thanks for that, IG.
