+2, have a Calvin Elite and Maritime bolt catch, no fitment issues and isn't sloppy in mine.
I have BCM on mine, it fits good. I’ve used the Geiselle LPK on a couple, they work good. I think the safety is milled in the wrong place, the detent feels weird.
Okay great! I was planning on waiting until Geisselle comes out with their in-house LPK, but with all the ban talk i'm ordering everything now. Is there another LPK that you would recommend?
I think the problem is with the Modern Sporter, not with the Geiselle LPK.
I really like the BCM enhanced LPK.

The location of the safety is correct, and the location for the detent. The thickness of the material behind the trigger is off slightly in the first run which is why we upgraded all first run receivers to use our ball bearing and set screw.
If you're having some issues I'd like if you could email us at the shop to discuss, as I'd like to ensure as much compatibility as possible with all reputable parts producers.
Took me longer then most because of health issues… but the first one is finally done…
For those that want to know what is what… from top to bottom, rear to front:
- NF NXS 2.5-10x42 MOAR, ADM 30 moa Recon mount, MS level, Buttler Creek covers, Magpul MBUS, Triad scope & crown cover,
- Limbsaver pad, Magpul CTR, V7 lightweight buffer tube, Armaspec captive buffer, V7 Ti castle nut, QD lock plate & buffer retainer, Ergo Deluxe grip & Ti nut,
- Brownells Paratrooper charging handle, lightweight BCG, BSF 20" fluted 6.5 Grendel, SLR Ti adjustable gas block, Brownells black gas tube,
- 13" Fortis Switch handguard & barrel nut, (14" is on the way), Magpul rail covers, MDT MLOK rail, ADM bipod QD, Harris BRS & Pod-Loc, JP Rifle comp,
- Ergo Deluxe grip, - CMMG upper and lower pin & spring kits, Timney Calvin Elite Gold trigger, PDQ ambidextrous bcg lock & release, V7 Ti: takedown pins, ambi safety, mag release, firing pin,
- 3BUCC camo brass catcher, Magpul MS4, a few ASC 10 rds pistol mags, a few Federal M205 AR (came in a case lot of 5000)…a few Hornady cases (came in a case lot of 3300), a few Hornady 123 ELDM (came in a case lot of 4000), sort of like why weiners come in 12 packs and buns in 8 packs?
- UTG 38” web case, Tactical Solution’s AR-22LR barrel & BCG conversion kit (on the way…), Dewey action guide, 2 piece take down rods, jags, brushes, patches…
Gun does 6.4 lbs with empty mag, without scope or pod.
Assembly was simple and straightforward. The MS receivers are spot on!
Will break it in slow & easy and work up loads. Going hog hunting in June. Summer is finally here!
Thank you to all who inspired it.

Beautiful build.
I gotta ask, how do you like the PDQ bolt release? I have been really thinking about putting that on one of mine. Does it function properly? Will it interfere with the ejection port cover (I heard it can, also I see that you didn't install a cover)?
Other than cutting the slot in the lower was there anything else you had to do?
Thanks for the input.

I love the PDQ and I think it's brilliant. It truly helps a right handed shooter and simplifies things !
I find the AR platform is awkward in engaging the bolt hold open when you want to do it quickly... such as when you get a jam in a rifle match...
If the right hand is holding the grip and the left hand is pulling the charging handle, you're short of a second left hand for the normal bolt open on the left side...
Install is real simple. Just continue milling the slot across (you can drill and file...), touch it up with Aluminum Black... and install it like any other hold open lever. I've converted all my ARs to PDQs and have NO regrets !
Cheers

Welcome for the info. 100 $ for a PDQ... no excuse not to have one !
Shooting update
For those wanting to know if a Modern Sporter can shoot accurately...
10 rounds, Hornady factory 123 grs, in about 1 minute, light breeze from 9 o'clock condition... @ 103 meters (114 yards) well under 1 moa...
If you look closely at the caliper, the group size is 1.2", edge to edge, @ 103 meters (114 yards)...
Correct me if the math is wrong... but this equals 1.053" at 100 yards (1.20/114x100)
- 2.64" for caliber diameter = .789" center to center
.789"/1.047" (value in inch of one moa at 100 yards) = .75 moa
Not bad for a 10 rounds group, fired under a minute, with factory ammo...

I put your group into my ballistic-x app. It spit out a .82 moa. That's still mighty impressive for 10 rounds in under a minute with a semi auto. Good shooting
When one has a toy he really likes... it is one of life's little pleasure and reward to use it well...
Thanks Greg.

What you're actually showing is that the BSF 20 inch barrel can shoot. The receiver set has very little to do with accuracy unless it's out of spec and the barrel is not held properly.
Nice shooting though, that's quite an impressive group for 10 rounds in under a minute.

Alright, I've made it through the entire first production run, EVERYONE has been contacted for any and all receiver types, slick side, forward assist, doesn't matter.
If you are in the first production run and you have ordered a forward assist upper, check your email. If you don't have an email, now is the time to contact us: info@albertatacticalrifle.com
For those of you in the second and third production runs, we are trying to avoid sending uppers and lowers out separately. By shipping them together, it gives us one last chance to go over them for quality control and make sure everything has a nice tight fit.
If you are in the second production run and you are adamant about getting your upper and lower shipped separately, you can also contact us at info@albertatacticalrifle.com
