    AR15/AR308 gas block compatability?

    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...

    260 Rem gas gun

    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

    Gas guns v. bolt guns in LR tact/sniper matches

    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...

    Adams Arms Gas Piston Review

    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...

    RRA Weaver type gas block question.

    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...

    Reloading for gas guns, tuning the gas system?

    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...

    Dissapator Gas Tube Length???

    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...

    Gunsmithing Adjustable gas block

    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...

    Range Report difference made by adjustable gas block

    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...

    Advanced Marksmanship Differences shooting gas versus bolt guns?

    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...
