Boot_Scraper Posted April 12, 2019 Report Share Posted April 12, 2019 Quick question fellers. I got my boss talked into building a 300 Blk. I see 2 options for gas length. I'm guessing pistol would be best if he planned to suppress it? Any pointers on building it? Gonna go with a 16" pipe. Thanks in advance!

Belt Fed Posted April 12, 2019 Report Share Posted April 12, 2019 Maybe just me but if I was goin with the 16 inch barrel it would be a carbine. That long of barrel kinda defeats the pistol for me. but that's just me. but I am biased. I really don't care much for the ar pistols.

Sisco Posted April 12, 2019 Report Share Posted April 12, 2019 (edited) Belt fed has a point. But another thing to consider, my Radical Arms 308 Blk came with a 16 inch barrel,, but is a pistol length gas system. And indeed, I shoot it suppressed with a non-adjsutable gas block with absolutely no problem with many different loads. I think that for 300 Blk the pistol length gas system might indeed give you a bit more flexibility. Edited April 12, 2019 by Sisco Quote Link to comment Share on other sites More sharing options...
jtallen83 Posted April 12, 2019 Report Share Posted April 12, 2019 No need for a 16 inch unless you want the rifle classification. The new braces are pretty much stocks, they do all the same things. The length loses advantage much past 10 inches. Pistol length gas will help with reliability for unsuppressed subs, I started with an adjustable block on a 10.5 inch pistol gas barrel, ended up with a standard block that works fine with everything.

Boot_Scraper Posted April 13, 2019 Author Report Share Posted April 13, 2019 Thank you gentlemen! I do believe the carbine would suit him best. On a side note, I started working at this place about 8 months ago and now have 4 guys that knew nothing about AR's, owning and wanting to building their own. I'd say the "enabler" training I recieved here has paid off. Quote Link to comment Share on other sites More sharing options...
Belt Fed Posted April 13, 2019 Report Share Posted April 13, 2019 I think a carbine would be a much more enjoyable experience if he is new to the AR platform. He can do more with it like scopes and being able to shoot farther with more accuracy. My pistol is fine for about 25 to 50 yards, beyond that it sucks. it has a 10.5 barrel. plus you can't shoot the damn thing without ear protection. now target shooting that's fine, I don't want to wear any hunting. I originally bought it to use as a home defense gun. after firing it I can't imagine shooting it in an enclosed building without hearing protection.. Guess a forward blast muzzle device would help.

I had no interest in a 300 BO until suppressors became legal in Iowa, building the third one now. We have no problem whacking a 12 inch gong at 100 yards, betting a 6 inch would rarely see a miss and this is with red dots and irons.

My home defense is an 10.5" SBR with a suppressor. I can easily shoot 2 moa at a 100 yds with subsonic rounds.. Quote Link to comment Share on other sites More sharing options...
Boot_Scraper Posted April 13, 2019 Author Report Share Posted April 13, 2019 (edited) He'll be hunting hogs with this and letting his son deer hunt with it. Got a Faxon Gunner 16" carbine on the way. Primary Arms has a good deal on them right now. I'll let y'all know how it goes. Thanks again. Edited April 13, 2019 by Boot_Scraper Quote Link to comment Share on other sites More sharing options...

Boot_Scraper Posted April 27, 2019 Author Report Share Posted April 27, 2019 Got em all squared up. Upper lapped, barrel bedded. I like how it came out. I've never been a fan of full length handguards but this one is kinda growing on me. Quote Link to comment Share on other sites More sharing options...
