Modern Sporter - Build Discussions

My build, after some parts swapping....will be built on the SS upper first and then transferred to the FA when ready.

BCM buffer tube assy
AAC nickle boron bcg
V7 short throw single side safety selector
Battle Arms mag release button
ALG ACT trigger
Raptor charging handle
Magpul K grip
Magpul fixed carbine stock (may swap out for a MFT Minimalist depending on final weight/balance)
V7 titanium micro brake
War Sport bolt catch
Strike Industries dust cover
BCM 15" MCMR handguard
BCM low pro gas block
Faxon 223 Wylde 20" heavy fluted barrel
 
The MS is going to replace my Modern Varmint as my go everywhere gun. I've already upgraded the optics on the MV so the MS can have the 1-6 Vortex Strike Eagle. My side by side is already setup to carry my MV, MS or anything else that will fit in the mount.

Love that mount . I’ll have to see about getting something similar for my commander . Just wonder how that will go over when the fish cops stop me to check plates and ins . Seems everytime me and the kids go out we get stopped

Thanks! I bought the parts and custom built it to fit. This is going to get used out on my parents acreage the most. The only time I've been checked is on long weekends and then I'm usually doing Search and Rescue patrols so they don't bother us to much. The MV would not be with me for SAR work though.

Nice setup.

The disheartening thing about being stopped by the “fish” cops is if they call in to check the serial number of your legal NR rifle it will be added to the firearms call police database. Such bull####.

I didn't think there was anything wrong with carrying firearms like that on ATVs. Heck, I thought you could carry NR firearms on motorcycles. Perhaps I'm wrong?

I think you are a bit optimistic on weight. I've build a few lightweight AR's, a couple of Stag 10's, a Maccabee & soon a ATRS MS. I keep a spreadsheet of all the AR parts I've bought & weighed over the years. There is always some variation in weight of parts from batch to batch & year to year, manufacturers also change stuff without telling anyone. There is always rounding error in the scales and scales can be off as well. I put the weights I have for those parts beside your post in Red if they are vastly different than what I have and green if they are the same. And of the 5 or 6 builds that I have measured the weight of EVERY part before assembly and then weighed the completed rifle, the completed rifle always weighs a bit more. I attribute this to the above mentioned rounding errors, loctite, lube, etc.

Surprisingly I have all the parts in your build list, except a Strike Industries buffer retainer & spring. I substituted a DPMS buffer retainer & spring instead for the LPK weight. But really you don't need a buffer retainer if running a JP SCSS.

You'll still have a VERY nice rifle, just a bit heavier than you think.



There is no way the BSF barrel weighs that. See link to their website. I would say it is safe to guess the weight of a 18.6" would be between their listed weights for the 18" & 20".

And for those to lazy to click on a link

Weight Chart
Length Fluted NOT Fluted
10" 18.3 oz 19.2 oz
12" 19.9 oz 22.1 oz
14" 21.6 oz 25.1 oz
16" 24.7 oz 26.9 oz
18" 26.6 oz 31.2 oz
20" 28.8 oz 33.7 oz
PLEASE TAKE NOTE: THE WEIGHT OF A FLUTED BARREL MAY VARY AN OUNCE OR SO DUE TO THE PROCESS OF FLUTING.

I know a couple of conservation officers here in BC, and they have told me that they don't ever call it in unless there's some sort of Investigation. For a random stop check, they don't bother.

And of course, if something were to happen with that in the future you sold your rifle a couple of months before they came knocking, right?

Easy enough to say until C71

Even after c71 they wont know about any rifles sold prior to c71.
And as far as I understand it personal sales of nr firearms aren't required to be recorded. If anyone voluntarily reports the private sale they aren't to brite.

Unfortunately, that is not correct.

Absolutely.

There's a reason I underlined and highlighted Registrar, and Reference number.

It should be interesting to see what compliance is like. I'm thinking it'll be significantly less than the 100% old Ralph is expecting.
 
I know I will be phoning the CFO everytime I buy a new firearm just to clarify that the rifle is not registered to me. Seeing as how this is
"Not a long gun registry"
 
So to sort of get us back on track (I think there are other threads for the legal stuff)....to dust cover or not? Has a dust cover ever saved your bacon, or ruined your day?
Comments from the sand box?
Forward assist....beaten to death I know, i LOVE that I could get the "slick slide", my first AR was an SP1 so that is how I think they should come. It seems that the majority here are running a FA upper....is it for the potential stealth option of quietly sneaking a round into battery? Sand box players?? Has a FA saved you bacon or just made a function problem worse? I know beaten to death elsewhere, but I still can't see the logic of "lets just jam that round that won't go in, in"....but maybe it works.
