Rocky Mountain Gun Owners
RMGO was established in the mid 1990s in Colorado by firearm rights advocate Dudley Brown. The group has become known for aggressive lobbying activities that have made their issues prominent, particularly in primaries and candidate nominating assemblies  and for its influence in firearms public policy such as Concealed Carry, Constitutional Carry, and Make My Day (more recently referred to as Castle Doctrine)  legislation.
RMGO maintains that it is Colorado’s only "no-compromise" gun rights lobby and  has attained distinction for its lobbying tactics that differ from other pro-gun organizations such as the National Rifle Association. The two organizations have exchanged heated criticisms of each other.
RMGO was established in 1996 and has been registered with the Colorado Secretary of State’s office since January of 1997. Dudley Brown, an NRA lobbyist throughout the early 1990s founded the group shortly after leaving the NRA state affiliate for being too lax on gun-control.
In the aftermath of the Columbine High School massacre Brown represented RMGO in national news in support of gun rights amidst calls for more restrictions on firearms. RMGO organized opposition to a 2000 state ballot initiative known as Amendment 22 aimed at closing the purported “gun-show loophole” by requiring background checks at gun shows. Amendment 22 ultimately passed. The group also organized opposition and demonstrations against legislative measures supported by then Republican Governor Bill Owens to restricting firearms access, and campaigned against candidates down to local sheriff that they felt undermined gun issues. RMGO's early years of influenced earned recognition in a state political science textbook.
Conflict with the NRA
From its early years RMGO has been at odds with other groups such as the National Rifle Association. RMGO has been recognized as “a gun-rights group so strident the National Rifle Association keeps its distance,”  and has accused the NRA of “squandering time and money” and ``kissing up to politicians.” 
The primary source of the tension has been reported as a difference in the lobbying tactics of the two groups. With NRA and its state affiliate Colorado State Shooting Association preferring a conventional lobbying or access-based approach, while RMGO electing to pursue a grassroots or confrontation-based approach. The group regularly accuses the NRA of not living up to its reputation.
The scope of the ideological differences was acknowledged more recently by Jim Merlino, former policy director for the Colorado Senate Democrats who observed: "Out here in Colorado, the National Rifle Association is considered a left-wing Washington-based organization. Instead of this Eastern establishment group, gun owners look to the Rocky Mountain Gun Owner as their voice in the legislature and Congress." 
During this time continued and RMGO built upon its tactics and message. An integral part of their efforts was their candidate survey, asking candidates for office a variety of questions on gun issues.
In 2003, RMGO was noted for its opposition to local county sheriffs revoking weapons permits issued by their predecessors. The group sought to address this issue and others through amendments to a concealed carry reform bill that year, however they ended up opposing the final bill due to added training requirements, and increased in the number of places off limits to weapons holders. Those provisions were acceptable to the NRA.
In 2004, the group lobbied for a bill that would have erased the Colorado Bureau of Investigation's database of concealed-weapons permit holders. Prior to 2007 permit holders were classified as "persons of interest" by the CBI. In 2007 the CBI moved permit holders out of that classification. Despite previous extensions of the law that allowed for the statewide database, the General Assembly did not renew the database and instead let it sunset.
In 2008, the group began lobbying for a bill to expand the Colorado "Make My Day" (Castle Doctrine) Law to businesses. An effort that continues to this day.
In 2010, the group was critical of republican gubernatorial candidate Dan Maes, amongst others for his response to their candidate survey.
Rocky Mountain Gun Owners is an affiliate of the National Association for Gun Rights, a group that serves as an umbrella coordinator for various state-level pro-gun organizations. NAGR is also headed by Dudley Brown. The two organizations submitted a joint Amicus curiae brief to the United States Supreme Court for the landmark 2010 McDonald v. Chicago case that determined the Second Amendment applies to individual states. The RMGO et al. brief was cited in the court's opinion. RMGO has also affiliations with Gun Owners of America and several other state-level gun organizations.
Campus carry lawsuits
In 2010 RMGO filed a lawsuit against Colorado State University for their attempt to ban Concealed Weapons Permit holders from carry-on-campus. CSU subsequently rescinded their ban and the lawsuit was dropped.
RMGO also argued against a similar campus carry ban by the University of Colorado. In 2012 Colorado Supreme Court ruled that CU's ban on the lawful carry of firearms was illegal, citing RMGO's Amicus Brief in its ruling that under Colorado Law the school's Board of Regents should not have "authority to regulate concealed handgun possession on campus".
In early 2012, the group was critical of Republican State Representative Jim Kerr's support of a measure that would have restricted gun sales on Sundays. Kerr sought appointment to a vacant State Senate seat that year, but Businessman Tim Neville was ultimately selected instead.
In February 2012, RMGO continued their efforts on behalf of the "Make My Day Better" bill by testifying and successfully advancing the bill through committee. At the state level, RMGO backed five gun bills during the 2012 legislative session.
In April 2012, RMGO presence was noted Colorado GOP convention, making firearms issues a prominent topic of discussion among delegates. RMGO threw their weight behind Randy Baumgardner in his race for Colorado Senate District 8 by opposing incumbent Republican Senator Jean White. RMGO's literature during the event called White's gun rights record into question and heralded Baumgardner for answering their survey 100%.
RMGO is an opponent of the Violence Policy Center, and calls their methods into question.
In 2012, the Denver Post accused the group of failing to file required documents with the Internal Revenue Service to maintain its tax-exempt status. The story ran one day before Colorado's State Primary Election.
RMGO-PAC supported local legislative candidates such as Vicki Marble, Owen Hill, Lori Saine, and Steve Humphrey, this keeping with the purported theme of supporting conservative candidates that answer their survey "pro-gun" over moderate candidates that do not. Each of these candidates prevailed in their Republican Primary Elections and in the General Election despite the fact that Republicans over all lost control of the State House of Representatives and failed to take control of the State Senate.
In 2013, RMGO assisted on the campaign to recall a Colorado State Senator, Evie Hudak, a democrat who voted in favor of more restrictive gun laws. The recall was cancelled when Senator Hudak resigned and was replaced by another Democratic Senator, Rachel Zenzinger. Senator Zenzinger lost her re-election bid in the midterm elections of 2014 to the RMGO-PAC endorsed Republican candidate, Laura J Woods. The effort of the RMGO-PAC on the 2014 midterm elections helped to change control of the Colorado State Senate from Democratic control to Republican control when three of their endorsed candidates won legislative seats.
In August 2014, the public library in Windsor, Colorado had their "no-gun" policy challenged by RMGO. The challenge occurred after a local resident had been asked to leave the library after a patron noticed that the citizen had a concealed handgun on her person. The library had a "no weapons" sign posted on the door of the building and had a policy that prohibited the carrying of guns in the library. RMGO told the library that their policy was not in accordance with state law and unless they changed the policy, the library would face legal action. In September 2014, the library board voted unanimously to change their policy and now allows concealed carry permit holders to carry guns in the library.
Other programs and services
RMGO provides information for firearms training, use of force for personal defense, and other gun rights materials on their website and offer firearms training courses that satisfy such legal requirement for individuals seeking to obtain a Colorado Concealed Weapons Permit.
The group also operates a merchant awareness program (MAP), allowing its members to list Colorado based businesses that opt to ban firearms in their premises.
