Will I have any trouble mating a RRA 10" pistol upper(.223) with a regular RRA lower. I ask this because the pistols have marked lowers when you buy the complete ar pistol.
thanks for your help Update: Sorry mods didnt see the pistol category, please move. I havnt been on the site in two or so years. |
| So I can buy a RRA pistol upper and then pick up a RRA complete lower with collapsible stock at the local gun shop? I haven't researched much into the legal aspects of it, i know i will need to get it registered and such. i was unsure if they make the pistol upper where it will only fit with a marked pistol lower? Sorry for my noobness. |

i was unsure if they make the pistol upper where it will only fit with a marked pistol lower Pistol-marked lowers are just standard lowers with "Pistol" engraved on the side. It's just a way for companies to charge more for the same exact lower that they otherwise sell for less money. (Just an FYI; you can build a rifle out of a pistol-marked lower. The marking holds zero legal weight.) Titlell is right......if you're talking about a stocked lower and a shorty upper, you're talking about an SBR, which involves a process of getting the stamp to do it legally. If that was just a typo or misunderstanding..........get the cheapest quality lower you can find for your pistol build. Don't pay extra money for one marked "Pistol". |
| good to know i plan on building an sbr and i'm aware that i will need to get the stamp for the sbr . My thinking is that i will buy a 10" RRA 'pistol' upper and build a pistol lower since im under 21 (one more damn yr). then once im 'legal' , get the lower register for an sbr and switch out the pistol buffer for a standard buffer. hope that makes sense. thanks again for the useful advise as i do not want to encounter any legal issues. |

i couldnt purchase it but i can legally shoot it and transport it. Kind of a gray area, i've talked to a few DPS officers and they all said the same. Have you heard otherwise? Actually, you can make an SBR at 18 years of age (Form 1). You can't buy one until 21 (Form 4), but you can make one. Contact the ATF for clarification. Pistols are typically frowned on until you're 21. Dumb rule, but that's how it is. |
| While there should be no "trouble" getting ANY Rock River upper to fit ANY Rock River lower, keep in mind that they have their receivers (upper and lower) milled with much tighter than normal tolerances. A factory upper and lower will be VERY tight the first time you put them together. Not a problem, just something to look at. My first RRA was bought as a separate complete lower and complete upper, and the guys I bought them from (two gun show tables side by side-wink, wink, nudge, nudge) used Tetra grease on the takedown lug and a rubber mallet to "pursuade" the two parts together, plus some taps on the takedown pin to get it to seat. It took about 40-50 cycles of breaking down the gun before it became as it is now: smooth and solid, with absolutely no resistance or effort involved in opening or closing the upper and lower. |
