Gonna put together a 7.5 pistol.. Im open to ideas on how you guys would make one. Ive got a few things picked out but Id like to tier 1 this bitch out just for shits and giggles. Help me become operator status  .... Actually Im in a rare spot of being able to kind of splurge on this (without getting just absolutely stupid)

So far Ive got the following ordered or have already

Spikes punisher lower
geissele super dynamic 3 gun trigger
spikes pistol buffer kit

I currently have in carts to order

From Primary Arms

Wheeler Roll Pin Punch Set
Seekins Precision Billet Magazine Release Button

From DSG Arms

Seekins Precision Ambi Safety Selector
Noveske Takedown and Pivot Pin Set
DSG AR15/M15 Enhanced Bolt Catch
SigTac SB15 Pistol Stabilizing Brace

Palmetto State

PSA Defender MOE Lower Parts Kit - No Ambi Safety -


Im open to suggestions on all of this stuff, well except the stuff Ive already bought ... Haven't made my mind up on an upper yet. Id like to buy one complete though. My last 7.5 barrel I had was a spikes with a kak flash can on it. I liked it but i cant seem to find that one anywhere.

Get a trust and do an sbr.

if you dont do an sbr get the kak tube and shockwave brace instead of the sb15. an adjustable gas block, heavy buffer and upgraded extractor will help it cycle correctly

I would use at least a 10.5 inch barrel.... my plan is a 12.5 for my next pistol upper.

I wanted to go with a 10.5 just to quite it down even just a little, not to mention helping clear up any gas problems.. But my gf wants the shortest thing possible...

She actually said that?!?! First woman to ever say those words  

Well then go 9" 300blk, a 7.5" 5.56 is a range toy that's about it. I agree if not going to SBR get the KAK Shockwave brace and tube

This is STRICTLY a range toy. She wants to stay with 556 to keep down on having different calibers. She already has a S&W AR..

I knew that comment would come back to bite me in the ass lol... but yes.. thats the only thing she prefers short

Why not finish off that Punisher lower with a matching Spikes billet upper? I have one on my 300 and its nice. Also would go over to SLR Rifleworks and start looking at their rails. Apparently your GF needs something tiny to get her hands wrapped around and they fit the bill

I'll say that my pistol was as much of a "build" as it was a "mod"...but here she is:



It began it's life as a 7.5" Rock River pistol. Out of the box, it ran flawlessly with quality ammo.

I landed up changing out the following:

Grip- Magpul MOE Sl grip (made for short LOP ARs)
Handguard- Seekins MCSR V2 7" rail
Flash hider- Smith Vortex
Buffer tube- KAK made forthe Sig brace (hated the Sig brace, sold it)
Sights- Magpul MBUS
Trigger- Rock River 2-stage match
Gas Block YHM low profile
Hand rest- BCM KAG

The sight mount is a LaRue, the sight is a Gen 2 Primary Arms micro.

The thing runs like a top. I know many will say that a pistol is over gassed, but mine actually requires higher quality ammo to cycle. My 16" carbine will eat Silver Bear .223 all day, this one will short stroke with the stuff (yes, even with a standard buffer). Wolf Gold runs great through it and is fairly affordable to shoot.

I had planned on going with you guys but checked out your 7.5 barrels and it showed out of stock..

Well damn. I ordered an upper yesterday- mid morning... I was going to send you an email but had noticed the site saying OOS so I just moved on...

Ive got a couple more lowers laying around. Gonna make another pistol out of one. You will be my first stop..
