gas

Need to know what the length is on a middy ar gas system is. Form end of barrel extension to gas block shoulder.

I have a question about gas blocks for AR's. Can you use an AR15 gas block on DPMS lr308's assuming the gas block locations are the same specs in diameter? I would like to build a 308 but find no gas blocks that are necessarily specific for them. I was thinking an Vltor, larue .750 size...

does anybody know someone who can make a custom gas block/tap for a ar-10?

Just returned from the range. Tried 38.8, 39.2, 39.6, 40.0m and 40.4 of N550 and 139 Scenars from a JP rifle. The 40 and 40.4 gave the best groups with avg. velocity of 2528 and 2570 respectively. Is the velocity enought or should I try for more. Thanks, Lance

In the LR rifle/sniper matches, what percentage of shooters are running gas guns? Seems like the % is pretty low and was wondering why? Are there matches where gas guns are not allowed? What are the advantages/disadvantages of the gas gun v. bolt gun in these matches? I've got a GAP TIS in...

Hi All, I recently purchased a rifle length gas piston system from Adams Arms for my 20" Krieger/CLE barreled rifle. My rifle previously worked flawlessly with a YHM gas block but I wanted to try the AA system as I have ordered a suppressor. Used a known-good Magpul 20-round magazine. SETUP...

Is the Rock River Arms Weaver type gas block in fact Weaver dimensions? Or is it actually Mil Std 1913 just marketed as Weaver? I am planning on mounting a Troy front BUIS using this gas block and wanted to know if it will fit correctly...

Would Reloader 15 be a good choice as a combo powder for gas guns in .223 and .308? was wanting to see if there is a decent powder to use for both

I recently purchased the complete adjustable gas system for my AR-10. My problem is I have all the parts stripped. The Super SASS manual doesn't describe or show an exploded drawing of the complete assembly. If anyone knows this assembly, I would greatly appreciate your help....

Does anyone here have experience with blc-2 in a 308 gas gun?

got a 22lr kit for ar, just wondering if its hard on an ar to run this then switch back to 5.56/.223? if its gonna be a pain to clean up after usin the rimfire ill just keep it for a ruck emergency kit....but it would be neat for cheaper training use if its not horrible on the rifling and gas...

I'm reloading for my LR308 with a Krieger 1:11 twist 20" barrel. I can get some great velocity of course at the cost of killing my brass after very few loadings. I was easily passing 2750 with 168gr AMAX bullets and Varget but my primer pockets were getting pretty loose and I tossed the brass...

I have a Bushmaster Dissapator and I want to switch the factory handguards for a 4 rail free float handguard. My question is what length handguard should I buy? I want the new handguard to cover the gas system but do not necessarily need the extra length of a rifle length handguard if it is not...

I finally got around to working on the AR10T gas block. I found that the brass was launched about 20'+ on good days. The reciprocation was violent as well. I increased the reciprocating mass with the Tubb CWS, but still the brass was getting hammered. I also got the Tubb spring and it slowed...

Just curious if anyone is running the same barrel that I am on their gas gun. Krieger 18" SS match 1:10

How much would my groups improve if I was shooting with the gas off (hand cycleing the weapon) vs. gas on (semi auto)? I own a panther SASS .308 with heavy 18 inch barrel. And also can I reach out to 1000 with this short of a barrel and still kill something such as a deer? I know this isn't the...

poll

For those with a good bit of experience behind both, do you change anything when shooting the gas guns? I would consider myself an "experienced" shooter with my bolt gun at this point. I've been shooting AR15/M16 style rifles for almost 20 years now but very little of that was spent working on...
