I need a new gas block for my Mini 14 (the screw sheared off in my current one). Can anyone tell me anything about the adjustable gas block from Accuracy Systems Inc? Is this worth the extra $ over the Ruger Factory gas block which is only $28, but requires factory installation? (No idea why the factory install is required 
)

New Accuracy Systems Tuneable Gas Block
Tired of hitting the fellow 3 shooting benches down in the head and him throwing the brass back at you?
Tired of having to change gas bushings only to find you didn't get the right diameter installed and had to start the process all over again?
Our new gas system will allow you to save all the lost brass that is ejected normally 20 to 30 feet by your factory gas system.
Our new gas system will save your scope as well as your receiver during the violent impact that happens every time you fire a round off and the operating rod whacks the receiver.
Our new gas system will actually help your rifle shoot better by reducing the harmonics that are produced when the operating rod comes in contact with your receiver during high speed cycling of the operating rod.
Our new gas system can be tuned from no cycling at all for you single shot bench shooters to wide open for you high capacity magazine junkies who don't care where there brass ends up.
*Our new gas block offers a factory look but with an enhanced feature of a user friendly Quick release sling swivel hole. Instead of the unfriendly non-removable factory sling loop. Ours is even the correct width so you can use the swivel of your choice.
Installation is as easy as removing the four factory screws that hold your gas block top and bottom together. Then installing our new gas block, new gas pipe, your gas bushing and putting your four factory screws back in. We then suggest that you load up a magazine and fire a round, notice where the brass lands then adjust the tuning screw a half turn and repeat the process till the out come you desire is met.
PRICE $89.95
