Feedback:

Chris:  Love the show. Have been listening since day one.  I just wanted to comment about something that was said in regards to eye dominance and shooting an AR. The conventional wisdom is one must always, and only, shoot with ones same eye as trigger finger. However, there are many with eye disease which must shoot in a cross dominant eye manner. To do this there are scope mounts which are so high that they allow you to look through an optic with one’s cross dominant eye. Obviously this will not work with iron sights. Thanks for all the great work.

Arturo:  Reed & Anthony, In ARP #85 you commented on feedback from a listener regarding their recommendation and use of a low mass bolt carrier from Rubber City Armory (RCA). Reed also mentioned he didn't see the need to switch from the standard carrier nor needing to worry about bolt carrier bounce or changing the cyclic timing of the bolt. By the way, in case you didn't know Chris Cerino works/consults with/for RCA.

Though bolt carrier and buffer weight has been used to tune select fire M4/M16's for smoother more reliable operation, the main reason for the low mass bolt carriers you see on the market for AR's today is to reduce felt recoil. They're used a lot by 3 gunners. However, to be effective they need to be used in conjunction with some way of adjusting the amount of gas used to cycle the bolt (typically via an adjustable gas block). What's innovative about Rubber City Armory is that they offer a low mass bolt carrier with an adjustable gas key, so you get a 2 in 1 function. It comes down to simple physics. You reduce and slow down as much as possible the amount of mass that moves rearward when a cartridge fires, and the felt recoil will be less. So you have to both reduce the weight of the bolt carrier and use just enough gas to cycle the action. Basically, enough so that the bolt will hold open on an empty mag after its shot with only 1 round loaded in the mag. The downside of course is that you can only tune for a particular load of ammo. Change the ammo and you'll have to re-adjust the amount of gas going to the bolt. Also, a gas key will be more cumbersome to adjust than a gas block, especially such as one made by Syrac Ordnance.

P.S. Anthony, you get that Tula/Wolf ammo working in your Bushmaster yet?

Adam K: I'm 99 percent sure that Huldra Arms is owned by Jason Adams, owner of Adams Arms. Fyi. Sorry for the presentation. Voice to text while driving.

Kiki: hey guys, love the show...was listening to past shows and came across full auto ar15s....you guys mentioned the lighting link...the lighting link was designed to work with semi auto parts only! no m16 parts! it was specifically designed to work with the colt sp1 bolt....the m16 bolt or newer bolts will not work, due to length of undercut on bottom of bolt, if you look at m16, ar15 and sp1 bolt you'll notice the under side are cut different lengths.....putting a lighting link on any other bolt than sp1 will cause your rifle to fire out of battery...theres youtube videos on this subject....anyways the good thing is that it works, the bad thing is after so many rounds, the link would have to be taken out and flattened back to shape. since its skinny and  soft metal and would bend out of shape and stop working.... hope this helps!

Patrick: Hey Guys, I recently started listening to your podcast after hearing one of you fill in on Gun Guy Radio. I like the show and I'm now looking to buy my first AR.  I'm looking at a Ruger 556E and a S&W M&P15T. I know that they are both different operating systems however they are about the same price at my FFL ($989 AND $919).

My question is…

(1) Which is the better value for the money?

(2) Which do you think a newbie like myself would enjoy more.

Thanks for your reply.

Greg: Reed, I have some feedback about the 5.45 podcast.  It seems as though you had some concern about being "stuck" with an increasingly unavailable round like the 5.45x39 in an AR-15. First, if you already own one, the round is still available in non-corrosive variety. While not as cheap as it was when it was a much more attractive option, it is still as cheap as comparable cartridges.  I own a S&W upper as well as a Ballistic Advantage barreled one (still available barrels).  As far as being stuck with them, should I run out of ammo (no way).  All that is required is a barrel and bolt change. That is no different than changing other calibers. If switching back to 5.56/.223 you could even reuse you flash hider and your gas block.  I can even reuse my 2nd gen. Magpul window mags.  Although I don't see that option in my future as I already have both, it is a valid point to make that you are not stuck with the cost of a whole new upper.  Keep up the podcast. I enjoy listening about the MSR while I work.

Network Feedback:

Doug Hartley (Powerfactor Show):  I use Viking Tactics 2 point slings on my long guns.  http://www.vikingtactics.com/product-p/vtac-mk1.htm  I like them because they are easily adjustable for my needs and are robust and reasonably priced.

Ryan Cross:  Coitac single point- generally the bungee kind with the option to swap out the attachment point for clip, swivel stud, etc.

Nick (Practically Tactical):  Hi Reed,  I currently have the MagPul MS3 Multi-Mission sling for running in a single point configuration. I tend to prefer one point as I think it gives a free-er range of motion and makes using my hands for non-firearm moves better.

I am, however, starting to look into 2 point slings and learning how to use them more effectively (I think that is why many people use a 1-point sling), I think I will be buying the Way Of The Gun ( sling. Here is a video on it: https://www.youtube.com/watch?v=TY3mMd2L8mc

Good Luck on the show,

Savage1r:  I like 2 point slings, because that's what I'm used to having and it secures the rifle well. I recently got a 1 point sling for my AR to try out, and it's ok, I'm just not a fan of the rifle bouncing around and having to hold it with one hand.

Jeremy P:  Condor Combat Bungee sling, in it's two point configuration. Like it because when set up it falls in front and keeps the rifle at the ready but doesn't swing around as much like a one point sling does, and can also be adjusted for use with body armor.

Michael C.:  Reed,  For tactical or patrol....or for patroling the streets in Iraq or Afghanastain = Viking Tactical Sling  (http://www.vikingtactics.com/product-p/vtac-mk2.htm)   I wish there had been a padded verision when I used it. For Competition I like the Turner Leather sling with the numbers (http://www.creedmoorsports.com/shop/Turner_Custom_made_Leather_Military_Rifle_Sling.html).  For an AR you need to use the 56", the standard military length of 48" is too short.  The 48 is for Garands and M1A / M-14. If you just want something neat to carry your rifle the paracord sling is kind of cool (http://www.creedmoorsports.com/shop/Paracord-GunSling.html) The Cobra Tactical BAT sling (http://www.cobratactical.com/Cobra-Tactical-BATS-Tactical-Weapon-Sling_p_3279.html) is kind of cool too, its based on the British Royal Commando sling used on the L85 rifle.  This sling allows you to put the rifle into backpack mode for climbing.  The one thing I don't like about the sling is you adjust it by reaching behind with your right hand.   Kind of hard to do if your shoulders are tight. Hope this helps.

Anthony M:  Hi Reed,  I'm a fan of the Magpul MS4 sling along with one of their stocks with a QD mount, ASP QD plate, and picatinny QD attachment. Its nice because it has the ability to be either a single or dual point sling with a quick reconfiguration of the push button QD mounts. Also the adjustment of the sling itself is fairly easy with the loop on the sling.

Sam A:  As far as slings go I only have one (i don't consider the tissue paper thing nylon sling the rifle came with a sling) sling. The Magpul MS3 It works great with the asap plate or any other one point anchor. the benefit in this sling is versatility in that it can be unhooked and utilized in a 2 point fashion. Im a big guy 6"7" 295 and its ergonomics leave something to be desired. it digs into my neck a bit.

Brad W.  here’s what i use for its versatility and ruggedness.  i like that i can quickly change from single point to two-point configuration in a couple seconds.  it's also super fast to adjust the tension in either config.

thanks!

Steven R:  VTAC original, it is super adjustable on the fly so you can adjust it to your gear when shooting, then make shorter to sling on your back when you need both hands and your whole front of body free. Inexpensive too. Its awesome.

Nikki T:  Hello guys, Here is one of my favorites designed by Bill Rogers of the legendary Rogers Shooting School for SAFARILAND. It is one of my favorites for men and/or women. Easy to install, easy to use!

http://www.youtube.com/watch?v=mW6sQ8kRZRU I am also a fan of the VTAC 2 point sling:  http://www.511tactical.com/vtac-2-point-sling.html Have a great podcast!!
