Have no use for bolt action pistols, but I've enjoyed the AR pistol in .300 BO, the CPL covers it being transported same as other pistols. The sba3 brace kicks the NFA in the nuts.

Flexible, expensive, and fun.

I used mine a couple of times... sold it within a month. Kinda like a Glock.. a soulless ugly gun.

A bolt action pistol is like a firearm designed by a committee.
(XP series excluded)
AR-based SBR or pistol seems to be the consensus.
And SBA3 FTW.

I have a Ruger American Ranch in 300 Blackout for running subsonics suppressed, and a Mega Arms AR15 8.75" build in 300blackout. Now I am building another Mega in 12"...or at least I am searching for parts to...

Subs will be run through an Obsidian 9 or 45. I am considering the purchase of a can to cover 5.56 and 300 blackout supersonic, but haven't decided if I will do it yet. I was looking at a discounted AAC Cyclone (new old stock) but found it to not be rated for 5.56 (crazy).

I had a H&R AAC single shot in 300blk. I experimented with hand loads as I had 30 cal bullets and 300 black brass at the time. It was fun for a project gun and project reloading. Otherwise I didn't see the need without a capable 30 caliber suppressor.

I believe 300blk is truly a silencer cartridge. It shines in subsonic form through a can

In my opinion, 7.62x39 is way cheaper if you want a bigger bullet than the .224 and are not going to be used suppressed.

 

[OR_VARMINT_HUNTER]

It will be used suppressed this time I have an omega 300

 

[Vrod]

Diamondback DB15GB Elite with Vortex Strikefire 1-8x24. 500 rounds and zero issues.

 

[Twodogs]

This is my 8" barreled 300 blk sbr. was setup to run suppressed but lately I've been shooting 110 gr supers without the suppresser.

I like where this thread is going.

Just last week finished the Mega Arms 300 Blackout build. I was going to do a build thread, but I guess I can post some info here:





In pictures is; Mega 300BLK, Ruger American Ranch in 300 Blackout and a CMMG AR15 with a 10.5" Rainier Arms match barrel in 5.56.

Mega build:
Mega Arms GTR-3H ambidextrous billet lower
Geissele SD-3G 3 gun single stage trigger
Arms Unlimited ambidextrous magazine release (black)
Timebomb black dimpled extended magazine release button (black)
Phase 5 extended billet ambidextrous safety (black)
Forward Controls Designs dimpled extended bolt catch/release (black)
Noveske takedown pins
ATI ergo pistol grip (probably to be swapped out for a Hogue soon)
Extended end plate with QD Sling mount, enhanced castle nut
Redcon Tactical lower spring kit. Standard buffer tube, spring for now (will probably install an Armaspec Stealth spring setup in 2 weeks)
SB Tactical SBM4 pistol brace and buffer tube (soon to probably swap out for an SB PDW or SBA3)
Magpul vintage new old stock straight 20s, a curved 20 for bench shooting/beating on, and a bunch of Pmag 30s

Mega Arms billet upper and 9" keymod handguard
Geissele Super Charging Handle
Strong Side Tactical fluted, bull 300 blackout 8.75" barrel
SLR Rifleworks gas block and pistol length gas tube
Lantac Enhanced Bolt Carrier Group
San-Tan Tactical dimpled forward assist
Impact Weapons Corp QD sling mount for top rail
RailScales HTP honeycomb keymod covers
RailScales keymod handstop
Vortex Strikeforce 1-6 with Vortex cantilever mount
Saker ASR muzzle brake

The next 12" Mega build is just starting. I haven't decided its final configuration yet. I might sell the CMMG receiver set and handguard to find the second Mega. I haven't found a matching billet Mega Arms GTR-3H lower yet. That will probably be a 12" blackout build. I haven't decided if I am going to get a suppressor to run supersonics yet.

Took the rifle pic out for you.

Which do u prefer to shoot more and how much quiter is the bolt over the pistol?

 

[saxon]

just finished fixing an undergased 16"carbine length gas 300 Blk
110 sierra reloads
110 hornady black v max
for CQB at 50 yards a 1/2 moa will do wonders

 

[Member 5605]

Depends what you want to do with it. If you want quite slugs going down range, then yes, you need a bolt. The semi-auto varieties are not quiet when the bolt is cycling.

Then I'm always thinking about silence where you only hear the hammer fall.
