Krylon on rubber? It should work, but spray lightly. If you lay it on too heavy the paint will flake off. Spray a little on a small area and check your results. If it sticks, you're good to go. If not, you might have to primer it first.

In basic we were always taught to ensure the gaps in the bolt rings were separated. Later, as I grew with the rifle I began to believe it's really a non-issue. If it's an add-on kit, I'd keep the piston rings on the bolt to minimize the amount of "wobble" or bolt bounce in the bolt as it unlocks and retracts into the bolt carrier. This allows the bolt carrier to stay on a truer course as it moves into and out of the receiver extension. Also, periodically check the lip of the receiver extension near the buffer detent for excessive wear.

About half a day with GooGone and elbow grease. The hardest parts were the plastic buttstock and pistol grip. The paint adhere'd better on those pieces than the steel and anodized aluminium.

Agree with running it wet; BCG should get a generous amount of lube, but not to the point you're getting spattered in the face with hot lube. Does the problem occur with all your mags or just one in particular? After lubing it and the problem persists, check for a canted/loose front sight base (FSB). This would limit the amount of gas vented down the gas tube. Also check the carrier key for looseness, this would cause a gas leak. Finally, check the buffer/buffer spring - something may be causing the buffer spring to bind or you might have to heavy of a buffer. HTH, RJM

Wow...Now THAT'S how you drift a thread. <thumbsup> Having rattle canned an AR or two in my day, it's pretty effective as a temporary cammo. Easy on, easy off. Because for some benighted reason, Uncle Sugar wants his rifles returned to him in the same condition he gave them to you.

Ya know, I was just thinking that 220 swift would be a better candidate than 22-250 because of the longer COL.

Indeed. 22-250 is a hot little bugger at ~4000 FPS.

Max COL of a 22-250 is 2.35 inches. You'd have to do some major jimmying to the mag and mag follower to make it work. It'd be interesting to see, though.

Both are great scopes for the money and you can't go wrong with either of them, IMO. BUt here's some food for thought: - Focal Plane: Both of the scopes you mention are second focal plane scopes. This means that the reticle will shrink or grow with the selected magnification. Most scopes of this type will have a certain magnification where the reticle is "True." (The owners manual will tell you what that mag factor is.) This is the magnification factor where you would zero the scope and where you would make sighting adjustments when shooting at distances outside the zero distance. Given your stated eye problems, you might want to look at a scope with a reticle in the first focal plane. An FFP reticle doesn't grow or shrink with the magnification, it stays the same size. This allows you to make precise sight adjustments throughout the magnification range instead of at a particular magnification or having to do a mathematical calculation. Reticles and Turrets - Both of the scopes you mention have mil-dot/milliradian reticles. However M1 turrets and the Accupoint turrets have .25 MOA adjustments. When estimating range to target you must convert from mils to yards/meters (more math) and when making sight adjustments you have to convert from mils to inches (yet more math!) The M5 turret makes metric adjustments - one click = 1 cm, which makes adjustments a little easier. The quickest way to make adjustments and eliminate a lot of pesky math is to get a scope that has reticle and turrets that match - either MOA/MOA or Mil/Mil. FWIW, Mil/Mil scopes allow for more precise adjustments. (There are 6283 mils in a circle vs 360 degrees.) Mounts - Almost as important as the scope itself. Get yourself a good set of mounts. Pay attention to the amount of adjustment they allow you. It should be on the package or in the user's manual and is usually expressed in mils or MOA. Don't get me started on ammo. That's a whole 'nother can of worms... HTH RJM

I was very interested in the precision 716 myself. A recent look on the Sig Sauer web site shows that model has been removed from the 716 section, leaving only the patrol rifle. My interest in the 716 has now cooled off.

Magpul makes rebuild kits for 5.56 mags. As for your .308 mags, it depends on the rifle they were made for. Magpul's .308 mags are made for KAC/DPMS pattern rifles. Armalite's mags are based on the M14 mag, and they offer refurb kits for their mags as well.

Upstate SC? My in-laws used to live in Greenville, SC while I was at Ft Jackson. Beautiful country up that way.

Thanks for the warm welcome, y'all. And it was my pleasure to serve; it was a very fulfilling and rewarding career. And it all started when my recruiter asked me, "How would you like an extra $75 a month in your paycheck?"

My AR10 replaced an ammo sensitive M1A Scout. I used to be a big fan of the rifle until I got a chance to use an M110 during my last tour. As someone else said, the M14/M1A community is always looking for original GI parts for their rifles. I got tired of "chasing the dragon," so to speak. It's hard accurizing an M14/M1A; it's even harder to keep it that way. Sure, you have to lube an AR more than and M14. But a bottle of lube is much cheaper than a NM op-rod. Plus mounting optics is way easier, parts are more readily available and the AR series (regardless of caliber) has waaaaay better ergonomics than the M14/M1A.

All, Stumbled across this site quite by accident while looking for some ideas for a new .308 AR. Read a bunch of posts and threads and thought it'd be a good idea to join. I retired at E8 in 2008 after 23 years of service in the Army, 11B5M. Spent most of my career at Bragg with 1 BCT and 18 ABC. Also have Stateside tours of Campbell, Jackson, and Sill. Overseas - West Berlin, Wilflecken, and JSA South Korea. Two Tours in Iraq and 1 in Afghanistan. Now I'm just an average guy, white collar type, one each. I currently own an Armalite AR10A4 carbine with NM trigger. I gotta say I was pleasantly surprised with it. I was expecting a 2 inch battle rifle. With plinking ammo, it would routinely do 1.5" groups, with match ammo about 1.25". I replaced the forend with the Armalite railed FF sleeve and get consistant 1" groups with match ammo. I've also replaced the M4 buttstock with a Magpul ACS unit. It's also been super reliable through 1000 rounds or so. It's rapidly becoming one of my favorite sticks. Happy to be here and hope to add positively to the discussion(s).
